151-561: This article is about all products under the brand "Radeon HD 2000 Series". They all contain a GPU which implements TeraScale 1 , ATI's first Unified shader model microarchitecture for PCs. The Unified Video Decoder (UVD) SIP core is on- die in the HD 2400 and the HD 2600. The HD 2900 GPU dies do not have a UVD core, as its stream processors were powerful enough to handle most of the steps of video acceleration in its stead except for entropy decoding and bitstream processing which are left for

302-693: A Centrino 2 platform demonstration system. The Mobility Radeon HD 3870 X2 was based on two M88 GPUs with the addition of a PCI Express switch chip on a single PCB. The development board used for demonstration was a PCI Express 2.0 ×16 card, while the final product is expected to be on AXIOM/ MXM modules. OpenGL 3.3 is possible with latest drivers for all RV6xx. Vertex shaders  : Pixel shaders  : Texture mapping units  : Render output units . Unified Shaderss  : Texture mapping units  : Render output units The following table shows features of AMD / ATI 's GPUs (see also: List of AMD graphics processing units ). @165 HZ AMD Catalyst

453-948: A PCI-E bridge splitting the PCI-E ×16 bandwidth into two groups of PCI-E ×8 lanes (each 2.0 Gbit/s). The card provides 4 DVI outputs or HDMI outputs via dongle and supports CrossFire configurations. AMD calls this product the Radeon HD 2600 X2 as seen by some vendors and as observed inside the INF file of Catalyst 7.9 version 8.411. Sapphire and other vendors including PowerColor and GeCube have either announced or demonstrated their respective dual GPU (connected by crossfire) products. Catalyst 7.9 added support for this hardware in September 2007. However, AMD did not provide much publicity to promote it. A vendor may offer cards containing 256 MiB, 512 MiB, or 1 GiB of video memory. Although

604-439: A target audience . Marketers tend to treat brands as more than the difference between the actual cost of a product and its selling price; rather brands represent the sum of all valuable qualities of a product to the consumer and are often treated as the total investment in brand building activities including marketing communications. Consumers may look on branding as an aspect of products or services, as it often serves to denote

755-469: A titulus pictus . The inscription typically specified information such as place of origin, destination, type of product and occasionally quality claims or the name of the manufacturer. Roman marks or inscriptions were applied to a very wide variety of goods, including, pots, ceramics, amphorae (storage/shipping containers) and on factory-produced oil-lamps. Carbonized loaves of bread , found at Herculaneum , indicate that some bakers stamped their bread with

906-417: A 420 mm die size. The Radeon HD 2900 XT was launched with 320 Stream Processors and a core clock of 743 MHz. The initial model was released with 512 MB of GDDR3 clocked at 828 MHz (1,656 MHz effective) with a 512-bit interface. A couple months after release ATI released the 1 GB GDDR4 model with a memory frequency of 1,000 MHz (2,000 MHz effective). Performance was on par compared to

1057-434: A 65 nm fabrication process. The Radeon HD 2400 series used a 64-bit-wide memory bus. The die size is 85 mm. The official PCB design implements only a passive-cooling heatsink instead of a fan, and official claims of power consumption are as little as 35 W. The core has 16 kiB unified vertex/texture cache away from dedicated vertex cache and L1/L2 texture cache used in higher end model. Reports has that

1208-621: A PCB had holes drilled for each wire of each component. The component leads were then inserted through the holes and soldered to the copper PCB traces. This method of assembly is called through-hole construction . In 1949, Moe Abramson and Stanislaus F. Danko of the United States Army Signal Corps developed the Auto-Sembly process in which component leads were inserted into a copper foil interconnection pattern and dip soldered . The patent they obtained in 1956

1359-426: A PCB may have a coating that protects the copper from corrosion and reduces the chances of solder shorts between traces or undesired electrical contact with stray bare wires. For its function in helping to prevent solder shorts, the coating is called solder resist or solder mask . The pattern to be etched into each copper layer of a PCB is called the "artwork". The etching is usually done using photoresist which

1510-636: A brand may recognize that advertising touchpoints are most effective during the pre-purchase experience stage therefore they may target their advertisements to new customers rather than to existing customers. Overall, a brand has the ability to strengthen brand equity by using IMC branding communications through touchpoints. Brand communication is important in ensuring brand success in the business world and refers to how businesses transmit their brand messages, characteristics and attributes to their consumers . One method of brand communication that companies can exploit involves electronic word-of-mouth (eWOM). eWOM

1661-400: A brand may showcase its primary attribute as environmental friendliness. However, a brand's attributes alone are not enough to persuade a customer into purchasing the product. These attributes must be communicated through benefits , which are more emotional translations. If a brand's attribute is being environmentally friendly, customers will receive the benefit of feeling that they are helping

1812-403: A brand name is a "memory heuristic": a convenient way to remember preferred product choices. A brand name is not to be confused with a trademark which refers to the brand name or part of a brand that is legally protected. For example, Coca-Cola not only protects the brand name, Coca-Cola , but also protects the distinctive Spencerian script and the contoured shape of the bottle. Brand identity

1963-463: A brand with consumers. For example, a jingle or background music can have a positive effect on brand recognition, purchasing behaviour and brand recall. Therefore, when looking to communicate a brand with chosen consumers, companies should investigate a channel of communication that is most suitable for their short-term and long-term aims and should choose a method of communication that is most likely to reach their target consumers. The match-up between

2114-478: A brand, the more they trusted the brand. This suggests that a company could look to employ a social-media campaign to gain consumer trust and loyalty as well as in the pursuit of communicating brand messages. McKee (2014) also looked into brand communication and states that when communicating a brand, a company should look to simplify its message as this will lead to more value being portrayed as well as an increased chance of target consumers recalling and recognizing

2265-518: A broad range of goods. In 1266, makers' marks on bread became compulsory in England. The Italians used brands in the form of watermarks on paper in the 13th century. Blind stamps , hallmarks , and silver-makers' marks —all types of brand—became widely used across Europe during this period. Hallmarks, although known from the 4th-century, especially in Byzantium, only came into general use during

2416-412: A category is differentiated from its competing brands, and thus the brand helps customers & potential customers understand which brand satisfies their needs. Thus, the brand offers the customer a short-cut to understanding the different product or service offerings that make up a particular category. Brand awareness is a key step in the customer's purchase decision process, since some kind of awareness

2567-417: A certain attractive quality or characteristic (see also brand promise). From the perspective of brand owners, branded products or services can command higher prices. Where two products resemble each other, but one of the products has no associated branding (such as a generic , store-branded product), potential purchasers may often select the more expensive branded product on the basis of the perceived quality of

2718-1021: A corporation hopes to accomplish, and to explain why customers should choose one brand over its competitors. Brand personality refers to "the set of human personality traits that are both applicable to and relevant for brands." Marketers and consumer researchers often argue that brands can be imbued with human-like characteristics which resonate with potential consumers. Such personality traits can assist marketers to create unique, brands that are differentiated from rival brands. Aaker conceptualized brand personality as consisting of five broad dimensions, namely: sincerity (down-to-earth, honest, wholesome, and cheerful), excitement (daring, spirited, imaginative, and up to date), competence (reliable, intelligent, and successful), sophistication (glamorous, upper class, charming), and ruggedness (outdoorsy and tough). Subsequent research studies have suggested that Aaker's dimensions of brand personality are relatively stable across different industries, market segments and over time. Much of

2869-527: A die size of 153 mm. Neither of the GDDR3 reference PCI-E designs required additional power connectors whereas the HD 2600 Pro and XT AGP variants required additional power through either 4-pin or 6-pin power connectors, Official claims state that the Radeon HD 2600 series consumes as little as 45 W of power. The Radeon HD 2600 X2 is a dual-GPU product which includes 2 RV630 dies on a single PCB with

3020-472: A different stage in a customer's cognitive ability to address the brand in a given circumstance. Marketers typically identify two distinct types of brand awareness; namely brand recall (also known as unaided recall or occasionally spontaneous recall ) and brand recognition (also known as aided brand recall ). These types of awareness operate in entirely different ways with important implications for marketing strategy and advertising. Brand recognition

3171-460: A flat, narrow part of the copper foil that remains after etching. Its resistance , determined by its width, thickness, and length, must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces . In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in

3322-418: A general estimate of the board complexity. Using more layers allow for more routing options and better control of signal integrity, but are also time-consuming and costly to manufacture. Likewise, selection of the vias for the board also allow fine tuning of the board size, escaping of signals off complex ICs, routing, and long term reliability, but are tightly coupled with production complexity and cost. One of

3473-462: A given category, when prompted with a brand name, a larger number of consumers are typically able to recognize it. Brand recognition is most successful when people can elicit recognition without being explicitly exposed to the company's name, but rather through visual signifiers like logos, slogans, and colors. For example, Disney successfully branded its particular script font (originally created for Walt Disney's "signature" logo ), which it used in

3624-493: A high level of brand equity. Brand owners manage their brands carefully to create shareholder value . Brand valuation is a management technique that ascribes a monetary value to a brand. The word brand , originally meaning a burning piece of wood, comes from a Middle English brand , meaning "torch", from an Old English brand . It became to also mean the mark from burning with a branding iron. Branding and labeling have an ancient history. Branding probably began with

3775-786: A liquid ink that contains electronic functionalities. HDI (High Density Interconnect) technology allows for a denser design on the PCB and thus potentially smaller PCBs with more traces and components in a given area. As a result, the paths between components can be shorter. HDIs use blind/buried vias, or a combination that includes microvias. With multi-layer HDI PCBs the interconnection of several vias stacked on top of each other (stacked vías, instead of one deep buried via) can be made stronger, thus enhancing reliability in all conditions. The most common applications for HDI technology are computer and mobile phone components as well as medical equipment and military communication equipment. A 4-layer HDI microvia PCB

3926-507: A low-involvement purchasing decision. Brand recognition is often the mode of brand awareness that operates in retail shopping environments. When presented with a product at the point-of-sale, or after viewing its visual packaging, consumers are able to recognize the brand and may be able to associate it with attributes or meanings acquired through exposure to promotion or word-of-mouth referrals. In contrast to brand recall, where few consumers are able to spontaneously recall brand names within

4077-446: A planar form such as stripline or microstrip with carefully controlled dimensions to assure a consistent impedance . In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; conversely, they can be used as a deliberate part of the circuit design, as in distributed-element filters , antennae , and fuses , obviating

4228-649: A print-and- etch method in the UK, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1925 patented a method of electroplating circuit patterns. Predating the printed circuit invention, and similar in spirit, was John Sargrove 's 1936–1947 Electronic Circuit Making Equipment (ECME) that sprayed metal onto a Bakelite plastic board. The ECME could produce three radio boards per minute. The Austrian engineer Paul Eisler invented

4379-600: A proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors , with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Harry W. Rubinstein its Cledo Brunetti Award for early key contributions to

4530-399: A receiver, it runs the risk of the receiver incorrectly interpreting the message. Therefore, a brand should use appropriate communication channels to positively "…affect how the psychological and physical aspects of a brand are perceived". In order for brands to effectively communicate to customers, marketers must "…consider all touch point |s, or sources of contact, that a customer has with

4681-414: A trademark from the late 1870s, with great success. Pears' soap , Campbell's soup , Coca-Cola , Juicy Fruit chewing gum and Aunt Jemima pancake mix were also among the first products to be "branded" in an effort to increase the consumer's familiarity with the product's merits. Other brands which date from that era, such as Ben's Original rice and Kellogg's breakfast cereal, furnish illustrations of

4832-407: A trademark in the form of a 'White Rabbit", which signified good luck and was particularly relevant to women, who were the primary purchasers. Details in the image show a white rabbit crushing herbs, and text includes advice to shoppers to look for the stone white rabbit in front of the maker's shop. In ancient Rome , a commercial brand or inscription applied to objects offered for sale was known as

4983-509: A visual or verbal cue. For example, when looking to satisfy a category need such as a toilet paper, the customer would firstly be presented with multiple brands to choose from. Once the customer is visually or verbally faced with a brand, they may remember being introduced to it before. When given a cue, consumers able to retrieve the memory node associated with the brand exhibit brand recognition. Often, this form of brand awareness assists customers in choosing one brand over another when faced with

5134-440: Is cotton paper impregnated with phenolic resin , often tan or brown. When a PCB has no components installed, it is less ambiguously called a printed wiring board ( PWB ) or etched wiring board . However, the term "printed wiring board" has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly ( PCA ), printed circuit board assembly or PCB assembly ( PCBA ). In informal usage,

5285-455: Is fire retardant , the dielectric constant (e r ), the loss tangent (tan δ), the tensile strength , the shear strength , the glass transition temperature (T g ), and the Z-axis expansion coefficient (how much the thickness changes with temperature). There are quite a few different dielectrics that can be chosen to provide different insulating values depending on the requirements of

5436-413: Is a brand's personality . Quite literally, one can easily describe a successful brand identity as if it were a person. This form of brand identity has proven to be the most advantageous in maintaining long-lasting relationships with consumers, as it gives them a sense of personal interaction with the brand Collectively, all four forms of brand identification help to deliver a powerful meaning behind what

5587-420: Is a collection of individual components, such as a name, a design, a set of images, a slogan, a vision, writing style, a particular font or a symbol etc. which sets the brand aside from others. For a company to exude a strong sense of brand identity, it must have an in-depth understanding of its target market, competitors and the surrounding business environment. Brand identity includes both the core identity and

5738-437: Is a common engineering error in high-frequency digital design; it increases the cost of the boards without a corresponding benefit. Signal degradation by loss tangent and dielectric constant can be easily assessed by an eye pattern . Moisture absorption occurs when the material is exposed to high humidity or water. Both the resin and the reinforcement may absorb water; water also may be soaked by capillary forces through voids in

5889-403: Is a fundamental asset to a brand's equity , the worth of a brand's identity would become obsolete without ongoing brand communication. Integrated marketing communications (IMC) relates to how a brand transmits a clear consistent message to its stakeholders . Five key components comprise IMC: The effectiveness of a brand's communication is determined by how accurately the customer perceives

6040-469: Is a precondition to purchasing. That is, customers will not consider a brand if they are not aware of it. Brand awareness is a key component in understanding the effectiveness both of a brand's identity and of its communication methods. Successful brands are those that consistently generate a high level of brand awareness, as this can be the pivotal factor in securing customer transactions. Various forms of brand awareness can be identified. Each form reflects

6191-410: Is a relatively new approach [Phelps et al., 2004] identified to communicate with consumers. One popular method of eWOM involves social networking sites (SNSs) such as Twitter . A study found that consumers classed their relationship with a brand as closer if that brand was active on a specific social media site (Twitter). Research further found that the more consumers "retweeted" and communicated with

6342-477: Is about 73, compared to about 4 for common circuit board materials. Absorbed moisture can also vaporize on heating, as during soldering , and cause cracking and delamination , the same effect responsible for "popcorning" damage on wet packaging of electronic parts. Careful baking of the substrates may be required to dry them prior to soldering. Often encountered materials: Less-often encountered materials: Copper thickness of PCBs can be specified directly or as

6493-468: Is an important consideration especially with ball grid array (BGA) and naked die technologies, and glass fiber offers the best dimensional stability. FR-4 is by far the most common material used today. The board stock with unetched copper on it is called "copper-clad laminate". With decreasing size of board features and increasing frequencies, small nonhomogeneities like uneven distribution of fiberglass or other filler, thickness variations, and bubbles in

6644-655: Is available to do much of the work of layout. Mass-producing circuits with PCBs is cheaper and faster than with other wiring methods, as components are mounted and wired in one operation. Large numbers of PCBs can be fabricated at the same time, and the layout has to be done only once. PCBs can also be made manually in small quantities, with reduced benefits. PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on

6795-575: Is being developed for Microsoft Windows and Linux . As of July 2014, other operating system are not officially supported. This may be different for the AMD FirePro brand, which is based on identical hardware but features OpenGL-certified graphics device drivers. AMD Catalyst supports of course all features advertised for the Radeon brand. The Purple Pill tool issue, which could allow unsigned drivers to be loaded into Windows Vista and tamper with

6946-451: Is coated onto the PCB, then exposed to light projected in the pattern of the artwork. The resist material protects the copper from dissolution into the etching solution. The etched board is then cleaned. A PCB design can be mass-reproduced in a way similar to the way photographs can be mass-duplicated from film negatives using a photographic printer . FR-4 glass epoxy is the most common insulating substrate. Another substrate material

7097-706: Is described by AMD as a milestone release, supporting DirectX 10.1, ATI CrossFire X technology and allowing the mixing of different Radeon HD 3800 series video cards to form a CrossFire X setup with 2 to 4 GPUs. Catalyst 8.3 introduced to new video controls to further enhance the video playback quality, these controls includes edge enhancement and noise reduction settings. There is also the support for extended desktop in CrossFire X mode. The anti-aliasing support for Unreal Engine 3.0 in DirectX 9.0 games, support for CFAA filters (wide tent and box tent) to be enabled when Super AA

7248-1149: Is enabled, and other features as developer support for hardware surface tessellation , hardware accelerated wide aspect ratio LCD scaling, HydraVision support for Windows Vista allowing to add maximum 9 virtual desktops and new Folding@home client are also officially supported in this release. The Catalyst 8.5, package version 8.493 brought new features include component video with 480i and 480p resolutions, SECAM TV output support, 1080p HDTV custom mode via HDMI, 1080p24 (1080p resolution at 24 Hz) support, HDMI Audio for non-standard TV modes (CEA 861b), support for adaptive anti-aliasing (and later, in Catalyst 8.6, also support for custom filters ) under OpenGL , Windows XP SP3 support and un-install utility enhancements. The driver also includes performance improvements and fixes some instability issues and rendering issues on some games. The Radeon HD 2000 series has been transitioned to legacy support, where drivers will be updated only to fix bugs instead of being optimized for new applications. Current Catalyst drivers do not support

7399-418: Is equivalent in quality to an 8-layer through-hole PCB, so HDI technology can reduce costs. HDI PCBs are often made using build-up film such as ajinomoto build-up film, which is also used in the production of flip chip packages. Some PCBs have optical waveguides, similar to optical fibers built on the PCB. A basic PCB consists of a flat sheet of insulating material and a layer of copper foil , laminated to

7550-632: Is estimated to reach $ 79 billion by 2024. Before the development of printed circuit boards, electrical and electronic circuits were wired point-to-point on a chassis. Typically, the chassis was a sheet metal frame or pan, sometimes with a wooden bottom. Components were attached to the chassis, usually by insulators when the connecting point on the chassis was metal, and then their leads were connected directly or with jumper wires by soldering , or sometimes using crimp connectors, wire connector lugs on screw terminals, or other methods. Circuits were large, bulky, heavy, and relatively fragile (even discounting

7701-421: Is often little to differentiate between several types of products in the 21st century, hence branding is among a few remaining forms of product differentiation . Brand equity is the measurable totality of a brand's worth and is validated by observing the effectiveness of these branding components. When a customer is familiar with a brand or favors it incomparably over its competitors, a corporation has reached

7852-442: Is one of the initial phases of brand awareness and validates whether or not a customer remembers being pre-exposed to the brand. Brand recognition (also known as aided brand recall ) refers to consumers' ability to correctly differentiate a brand when they come into contact with it. This does not necessarily require consumers to identify or recall the brand name. When customers experience brand recognition, they are triggered by either

8003-406: Is stronger than brand recognition, as the brand must be firmly cemented in the consumer's memory to enable unassisted remembrance. This gives the company huge advantage over its competitors because the customer is already willing to buy or at least know the company offering available in the market. Thus, brand recall is a confirmation that previous branding touchpoints have successfully fermented in

8154-564: Is the herbal paste known as chyawanprash , consumed for its purported health benefits and attributed to a revered rishi (or seer) named Chyawan. One well-documented early example of a highly developed brand is that of White Rabbit sewing needles, dating from China's Song dynasty (960 to 1127 CE). A copper printing plate used to print posters contained a message which roughly translates as: "Jinan Liu's Fine Needle Shop: We buy high-quality steel rods and make fine-quality needles, to be ready for use at home in no time." The plate also includes

8305-471: Is the most common thickness; 2 oz (70 μm) and 0.5 oz (17.5 μm) thickness is often an option. Less common are 12 and 105 μm, 9 μm is sometimes available on some substrates. Flexible substrates typically have thinner metalization. Metal-core boards for high power devices commonly use thicker copper; 35 μm is usual but also 140 and 400 μm can be encountered. In the US, copper foil thickness

8456-784: The Qin dynasty (221-206 BCE); large numbers of seals survive from the Harappan civilization of the Indus Valley (3,300–1,300 BCE) where the local community depended heavily on trade; cylinder seals came into use in Ur in Mesopotamia in around 3,000 BCE, and facilitated the labelling of goods and property; and the use of maker's marks on pottery was commonplace in both ancient Greece and Rome. Identity marks, such as stamps on ceramics, were also used in ancient Egypt. Diana Twede has argued that

8607-449: The glass transition temperature the resin in the composite softens and significantly increases thermal expansion; exceeding T g then exerts mechanical overload on the board components - e.g. the joints and the vias. Below T g the thermal expansion of the resin roughly matches copper and glass, above it gets significantly higher. As the reinforcement and copper confine the board along the plane, virtually all volume expansion projects to

8758-478: The marketing and communication techniques and tools that help to distinguish a company or products from competitors, aiming to create a lasting impression in the minds of customers . The key components that form a brand's toolbox include a brand's identity, personality, product design , brand communication (such as by logos and trademarks ), brand awareness , brand loyalty , and various branding ( brand management ) strategies. Many companies believe that there

8909-399: The signal propagation speed , frequency dependence introduces phase distortion in wideband applications; as flat a dielectric constant vs frequency characteristics as is achievable is important here. The impedance of transmission lines decreases with frequency, therefore faster edges of signals reflect more than slower ones. Dielectric breakdown voltage determines the maximum voltage gradient

9060-481: The "consumer packaging functions of protection, utility and communication have been necessary whenever packages were the object of transactions". She has shown that amphorae used in Mediterranean trade between 1,500 and 500 BCE exhibited a wide variety of shapes and markings, which consumers used to glean information about the type of goods and the quality. The systematic use of stamped labels dates from around

9211-484: The "cool" factor. This began the modern practice now known as branding , where the consumers buy the brand instead of the product and rely on the brand name instead of a retailer's recommendation. The process of giving a brand "human" characteristics represented, at least in part, a response to consumer concerns about mass-produced goods. The Quaker Oats Company began using the image of the Quaker Man in place of

9362-400: The "…potential to add positive – or suppress negative – associations to the brand's equity" Thus, a brand's IMC should cohesively deliver positive messages through appropriate touch points associated with its target market. One methodology involves using sensory stimuli touch points to activate customer emotion. For example, if a brand consistently uses a pleasant smell as a primary touchpoint,

9513-518: The 1st century CE. The use of hallmarks , a type of brand, on precious metals dates to around the 4th century CE. A series of five marks occurs on Byzantine silver dating from this period. Some of the earliest use of maker's marks, dating to about 1,300 BCE, have been found in India. The oldest generic brand in continuous use, known in India since the Vedic period ( c.  1100 BCE to 500 BCE),

9664-462: The 512 MB card. The HD 2900 XT introduced a lot of firsts. It was the first to implement a digital PWM on board (7-phase PWM), first to use an 8-pin PEG connector, and was the first graphics card from ATI to support DirectX 10 . The Radeon HD 2900 Pro was clocked lower at 600 MHz core and 800 MHz memory (1,600 MHz effective), configured with 512 MB of GDDR3 or 1 GB of GDDR4. It

9815-606: The 6th century BCE. A vase manufactured around 490 BCE bears the inscription " Sophilos painted me", indicating that the object was both fabricated and painted by a single potter. Branding may have been necessary to support the extensive trade in such pots. For example, 3rd-century Gaulish pots bearing the names of well-known potters and the place of manufacture (such as Attianus of Lezoux , Tetturo of Lezoux and Cinnamus of Vichy ) have been found as far away as Essex and Hadrian's Wall in England. English potters based at Colchester and Chichester used stamps on their ceramic wares by

9966-452: The AGP versions of Radeon HD 2000/3000 series cards with RIALTO bridge. Installing Catalyst drivers on those cards will yield the following error message: "setup did not find a driver compatible with your current hardware or operating system." or simply fail outright. The AGP cards in question are supported unofficially by ATI/AMD with a hot-fixed Catalyst driver-set each month since May 2008 with

10117-801: The AtomBIOS ROM routines were released in September 2007. The R600 family Instruction Set Architecture guide was released on June 11, 2008. Sample code and register headers for the R600 and R700 3D engines were released in December 2008. AMD released the specifications for both the r6xx and r7xx families on January 26, 2009. Brand A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business , marketing , and advertising for recognition and, importantly, to create and store value as brand equity for

10268-611: The CPU to perform. HDTV encoding support is implemented via the integrated AMD Xilleon encoder; the companion Rage Theater chip used on the Radeon X1000 series was replaced with the digital Theater 200 chip, providing VIVO capabilities. For display outputs, all variants include two dual-link TMDS transmitters, except for HD 2400 and HD 3400, which include one single and one dual-link TMDS transmitters. Each DVI output includes dual-link HDCP encoder with on-chip decipher key. HDMI

All Mobility Radeon HD 2000 series share the same feature set support as their desktop counterparts, as well as the addition of the battery-conserving PowerPlay 7.0 features, which are augmented from the previous generation's PowerPlay 6.0. The Mobility Radeon HD 2300 is a budget product which includes UVD in silica but lacks unified shader architecture and DirectX 10.0/ SM 4.0 support, limiting support to DirectX 9.0c/SM 3.0 using

10721-534: The Medieval period. British silversmiths introduced hallmarks for silver in 1300. Some brands still in existence as of 2018 date from the 17th, 18th, and 19th centuries' period of mass-production. Bass Brewery , the British brewery founded in 1777, became a pioneer in international brand marketing. Many years before 1855, Bass applied a red triangle to casks of its pale ale. In 1876, its red-triangle brand became

10872-558: The PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities. Surface mounting lends itself well to a high degree of automation, reducing labor costs and greatly increasing production rates compared with through-hole circuit boards. Components can be supplied mounted on carrier tapes. Surface mount components can be about one-quarter to one-tenth of

11023-476: The atrium, and bearing labels as follows: Scaurus' fish sauce was known by people across the Mediterranean to be of very high quality, and its reputation traveled as far away as modern France. In both Pompeii and nearby Herculaneum, archaeological evidence also points to evidence of branding and labeling in relatively common use across a broad range of goods. Wine jars, for example, were stamped with names, such as "Lassius" and "L. Eumachius"; probably references to

11174-453: The back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine. Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s, and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto

11325-524: The barrels used, effectively using a corporate trademark as a quasi-brand. Factories established following the Industrial Revolution introduced mass-produced goods and needed to sell their products to a wider market—that is, to customers previously familiar only with locally produced goods. It became apparent that a generic package of soap had difficulty competing with familiar, local products. Packaged-goods manufacturers needed to convince

11476-427: The beginnings of brand management. This trend continued to the 1980s, and as of 2018 is quantified by marketers in concepts such as brand value and brand equity . Naomi Klein has described this development as "brand equity mania". In 1988, for example, Philip Morris Companies purchased Kraft Foods Inc. for six times what the company was worth on paper. Business analysts reported that what they really purchased

11627-437: The board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on

11778-401: The brand and is termed the consumer's brand experience . The brand is often intended to create an emotional response and recognition, leading to potential loyalty and repeat purchases. The brand experience is a brand's action perceived by a person. The psychological aspect, sometimes referred to as the brand image , is a symbolic construct created within the minds of people, consisting of all

11929-412: The brand has a much higher chance of creating a positive lasting effect on its customers' senses as well as memory. Another way a brand can ensure that it is utilizing the best communication channel is by focusing on touchpoints that suit particular areas associated with customer experience . As suggested Figure 2, certain touch points link with a specific stage in customer-brand-involvement. For example,

12080-413: The brand or on the basis of the reputation of the brand owner. Brand awareness involves a customer's ability to recall and/or recognize brands, logos, and branded advertising. Brands help customers to understand which brands or products belong to which product or service category. Brands assist customers to understand the constellation of benefits offered by individual brands, and how a given brand within

12231-425: The brand". Touch points represent the channel stage in the traditional communication model, where a message travels from the sender to the receiver. Any point where a customer has an interaction with the brand - whether watching a television advertisement, hearing about a brand through word of mouth or even noticing a branded license plate – defines a touchpoint. According to Dahlen et al. (2010), every touchpoint has

12382-400: The brand's intended message through its IMC. Although IMC is a broad strategic concept, the most crucial brand communication elements are pinpointed to how the brand sends a message and what touch points the brand uses to connect with its customers [Chitty 2005]. One can analyze the traditional communication model into several consecutive steps: When a brand communicates a brand identity to

12533-509: The brand, he or she is more likely to try other products offered by the company – such as chocolate-chip cookies, for example. Brand development, often performed by a design team , takes time to produce. A brand name is the part of a brand that can be spoken or written and identifies a product, service or company and sets it apart from other comparable products within a category. A brand name may include words, phrases, signs, symbols, designs, or any combination of these elements. For consumers,

12684-455: The brand. In 2012 Riefler stated that if the company communicating a brand is a global organization or has future global aims, that company should look to employ a method of communication that is globally appealing to their consumers, and subsequently choose a method of communication with will be internationally understood. One way a company can do this involves choosing a product or service's brand name, as this name will need to be suitable for

12835-519: The breakable glass envelopes of the vacuum tubes that were often included in the circuits), and production was labor-intensive, so the products were expensive. Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented

12986-524: The ceramic substrate. In 1948, the US released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in the UK work along similar lines was carried out by Geoffrey Dummer , then at the RRDE . Motorola was an early leader in bringing

13137-539: The circuit. Some of these dielectrics are polytetrafluoroethylene (Teflon), FR-4, FR-1, CEM-1 or CEM-3. Well known pre-preg materials used in the PCB industry are FR-2 (phenolic cotton paper), FR-3 (cotton paper and epoxy), FR-4 (woven glass and epoxy), FR-5 (woven glass and epoxy), FR-6 (matte glass and polyester), G-10 (woven glass and epoxy), CEM-1 (cotton paper and epoxy), CEM-2 (cotton paper and epoxy), CEM-3 (non-woven glass and epoxy), CEM-4 (woven glass and epoxy), CEM-5 (woven glass and polyester). Thermal expansion

13288-488: The components to the board. Another manufacturing process adds vias , drilled holes that allow electrical interconnections between conductive layers. Printed circuit boards are used in nearly all electronic products. Alternatives to PCBs include wire wrap and point-to-point construction , both once popular but now rarely used. PCBs require additional design effort to lay out the circuit, but manufacturing and assembly can be automated. Electronic design automation software

13439-431: The components, test points , or identifying text. Originally, silkscreen printing was used for this purpose, but today other, finer quality printing methods are usually used. Normally the legend does not affect the function of a PCBA. A printed circuit board can have multiple layers of copper which almost always are arranged in pairs. The number of layers and the interconnection designed between them (vias, PTHs) provide

13590-412: The conductive layers is designed with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers, generally by means of soldering , which both electrically connects and mechanically fastens

13741-501: The consumer through branding. Producers began by attaching simple stone seals to products which, over time, gave way to clay seals bearing impressed images, often associated with the producer's personal identity thus giving the product a personality. Not all historians agree that these markings are comparable with modern brands or labels, with some suggesting that the early pictorial brands or simple thumbprints used in pottery should be termed proto-brands while other historians argue that

13892-471: The desired final thickness and dielectric characteristics. Available standard laminate thickness are listed in ANSI/IPC-D-275. The cloth or fiber material used, resin material, and the cloth to resin ratio determine the laminate's type designation (FR-4, CEM -1, G-10 , etc.) and therefore the characteristics of the laminate produced. Important characteristics are the level to which the laminate

14043-432: The development of a third party driver patch, "ExDeus ATI HD Registry Tweak", to unlock the potential of HD 2400 Pro for full support of H.264/VC-1 hardware video decoding. The Radeon HD 2600 series was based on the codenamed RV630 GPU and packed 390 million transistors on a 65 nm fabrication process. The Radeon HD 2600-series video cards included GDDR3 support, a 128-bit memory ring bus and 4-phase digital PWM, spanning

14194-498: The development of printed components and conductors on a common insulating substrate. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison , for his innovations in the technology of printed electronic circuits and the fabrication of capacitors. This invention also represents a step in the development of integrated circuit technology, as not only wiring but also passive components were fabricated on

14345-403: The dielectric constant). The reinforcement type defines two major classes of materials: woven and non-woven. Woven reinforcements are cheaper, but the high dielectric constant of glass may not be favorable for many higher-frequency applications. The spatially nonhomogeneous structure also introduces local variations in electrical parameters, due to different resin/glass ratio at different areas of

14496-516: The environment by associating with the brand. Aside from attributes and benefits, a brand's identity may also involve branding to focus on representing its core set of values . If a company is seen to symbolize specific values, it will, in turn, attract customers who also believe in these values. For example, Nike's brand represents the value of a " just do it " attitude. Thus, this form of brand identification attracts customers who also share this same value. Even more extensive than its perceived values

14647-414: The extended identity. The core identity reflects consistent long-term associations with the brand; whereas the extended identity involves the intricate details of the brand that help generate a constant motif. According to Kotler et al. (2009), a brand's identity may deliver four levels of meaning: A brand's attributes are a set of labels with which the corporation wishes to be associated. For example,

14798-405: The finished multilayer board) are plated-through, before the layers are laminated together. Only the outer layers need be coated; the inner copper layers are protected by the adjacent substrate layers. "Through hole" components are mounted by their wire leads passing through the board and soldered to traces on the other side. "Surface mount" components are attached by their leads to copper traces on

14949-594: The first batch of the RV610 core (silicon revision A12), only being released to system builders , has a bug that hindered the UVD from working properly, but other parts of the die operated normally. Those products were officially supported with the release of Catalyst 7.10 driver, which the cards were named as Radeon HD 2350 series. Several reports from owners of HD 2400 Pro suggest the card do not fully support hardware decoding for all H.264/VC-1 videos. The device driver, even with

15100-426: The first registered trademark issued by the British government. Guinness World Records recognizes Tate & Lyle (of Lyle's Golden Syrup ) as Britain's, and the world's, oldest branding and packaging, with its green-and-gold packaging having remained almost unchanged since 1885. Twinings tea has used the same logo – capitalized font beneath a lion crest – since 1787, making it

15251-642: The fourth century BCE. In largely pre-literate society, the shape of the amphora and its pictorial markings conveyed information about the contents, region of origin and even the identity of the producer, which were understood to convey information about product quality. David Wengrow has argued that branding became necessary following the urban revolution in ancient Mesopotamia in the 4th century BCE, when large-scale economies started mass-producing commodities such as alcoholic drinks, cosmetics and textiles. These ancient societies imposed strict forms of quality-control over commodities, and also needed to convey value to

15402-592: The industry's first implementation of on-board 128-bit GDDR4 memory. About the time of late March to early April, 2008, AMD renewed the device ID list on its website with the inclusion of Mobility Radeon HD 3850 X2 and Mobility Radeon HD 3870 X2 and their respective device IDs. Later in Spring IDF 2008 held in Shanghai, a development board of the Mobility Radeon HD 3870 X2 was demonstrated alongside

15553-436: The information and expectations associated with a product, with a service, or with the companies providing them. Marketers or product managers that responsible for branding, seek to develop or align the expectations behind the brand experience, creating the impression that a brand associated with a product or service has certain qualities or characteristics, which make it special or unique. A brand can, therefore, become one of

15704-447: The inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology . However, multilayer PCBs make repair, analysis, and field modification of circuits much more difficult and usually impractical. The world market for bare PCBs exceeded $ 60.2 billion in 2014 and

15855-427: The internal layers is used as ground plane or power plane, to achieve better signal integrity, higher signaling frequencies, lower EMI, and better power supply decoupling. In multi-layer boards, the layers of material are laminated together in an alternating sandwich: copper, substrate, copper, substrate, copper, etc.; each plane of copper is etched, and any internal vias (that will not extend to both outer surfaces of

16006-487: The latest stable version, seem to only honor hardware decoding for formats specified in the Blu-ray and HD-DVD specification. As a result of such restriction, the card is not deemed very useful for hardware video decoding since the majority of the H.264/VC-1 videos on the net are not encoded in those formats (even though the hardware itself is fully capable of doing such decoding work). This device driver restriction has led to

16157-430: The literature on branding suggests that consumers prefer brands with personalities that are congruent with their own. Consumers may distinguish the psychological aspect (brand associations like thoughts, feelings, perceptions, images, experiences, beliefs, attitudes, and so on that become linked to the brand) of a brand from the experiential aspect. The experiential aspect consists of the sum of all points of contact with

16308-419: The logo for go.com . Unlike brand recognition, brand recall (also known as unaided brand recall or spontaneous brand recall ) is the ability of the customer retrieving the brand correctly from memory. Rather than being given a choice of multiple brands to satisfy a need, consumers are faced with a need first, and then must recall a brand from their memory to satisfy that need. This level of brand awareness

16459-473: The market that the public could place just as much trust in the non-local product. Gradually, manufacturers began using personal identifiers to differentiate their goods from generic products on the market. Marketers generally began to realize that brands, to which personalities were attached, outsold rival brands. By the 1880s, large manufacturers had learned to imbue their brands' identity with personality traits such as youthfulness, fun, sex appeal, luxury or

16610-540: The marketplace that it aims to enter. It is important that if a company wishes to develop a global market, the company name will also need to be suitable in different cultures and not cause offense or be misunderstood. When communicating a brand, a company needs to be aware that they must not just visually communicate their brand message and should take advantage of portraying their message through multi-sensory information. One article suggests that other senses, apart from vision, need to be targeted when trying to communicate

16761-498: The material can be subjected to before suffering a breakdown (conduction, or arcing, through the dielectric). Tracking resistance determines how the material resists high voltage electrical discharges creeping over the board surface. Loss tangent determines how much of the electromagnetic energy from the signals in the conductors is absorbed in the board material. This factor is important for high frequencies. Low-loss materials are more expensive. Choosing unnecessarily low-loss material

16912-495: The materials and along the reinforcement. Epoxies of the FR-4 materials are not too susceptible, with absorption of only 0.15%. Teflon has very low absorption of 0.01%. Polyimides and cyanate esters, on the other side, suffer from high water absorption. Absorbed water can lead to significant degradation of key parameters; it impairs tracking resistance, breakdown voltage, and dielectric parameters. Relative dielectric constant of water

17063-429: The memory technology utilized is at a vendor's discretion, most vendors have opted for GDDR3 and DDR2 due to lower manufacturing cost and positioning of this product for the mainstream rather than performance market segment and also a big success. The Radeon HD 2900 series was based on the codenamed R600 GPU and was launched on May 14, 2007. R600 packed 700 million transistors on an 80 nm fabrication process and had

17214-400: The minds of its consumers. Marketing-mix modeling can help marketing leaders optimize how they spend marketing budgets to maximize the impact on brand awareness or on sales. Managing brands for value creation will often involve applying marketing-mix modeling techniques in conjunction with brand valuation . Brands typically comprise various elements, such as: Although brand identity

17365-423: The more traditional architecture of the previous generation. A high-end variant, the Mobility Radeon HD 2700, with higher core and memory frequencies than the Mobility Radeon HD 2600, was released in mid-December 2007. The Mobility Radeon HD 2400 is offered in two model variants; the standard HD 2400 and the HD 2400 XT. The Mobility Radeon HD 2600 is also available in the same two flavors; the plain HD 2600 and, at

17516-433: The most enduring campaigns of the 20th-century. Brand advertisers began to imbue goods and services with a personality, based on the insight that consumers searched for brands with personalities that matched their own. Effective branding, attached to strong brand values, can result in higher sales of not only one product, but of other products associated with that brand. If a customer loves Pillsbury biscuits and trusts

17667-579: The most valuable elements in an advertising theme, as it demonstrates what the brand owner is able to offer in the marketplace . This means that building a strong brand helps to distinguish a product from similar ones and differentiate it from competitors. The art of creating and maintaining a brand is called brand management . The orientation of an entire organization towards its brand is called brand orientation . Brand orientation develops in response to market intelligence . Careful brand management seeks to make products or services relevant and meaningful to

17818-564: The name of the producer. The use of identity marks on products declined following the fall of the Roman Empire . In the European Middle Ages , heraldry developed a language of visual symbolism which would feed into the evolution of branding, and with the rise of the merchant guilds the use of marks resurfaced and was applied to specific types of goods. By the 13th century, the use of maker's marks had become evident on

17969-498: The need for additional discrete components. High density interconnects (HDI) PCBs have tracks or vias with a width or diameter of under 152 micrometers. Laminates are manufactured by curing layers of cloth or paper with thermoset resin under pressure and heat to form an integral final piece of uniform thickness. They can be up to 4 by 8 feet (1.2 by 2.4 m) in width and length. Varying cloth weaves (threads per inch or cm), cloth thickness, and resin percentage are used to achieve

18120-412: The object identified, to the benefit of the brand's customers, its owners and shareholders . Brand names are sometimes distinguished from generic or store brands . The practice of branding—in the original literal sense of marking by burning—is thought to have begun with the ancient Egyptians , who are known to have engaged in livestock branding and branded slaves as early as 2,700 BCE. Branding

18271-734: The operating system kernel , was resolved in the Catalyst 7.8 release (version 8.401). The AVIVO video converter for Windows Vista , and color temperature control in Catalyst Control Center was added with the release of Catalyst 7.9, package version 8.411. Software CrossFire was enabled for HD 2600 and HD 2400 series video cards with the release of Catalyst 7.10 (package version 8.421) The Catalyst 8.1, package version 8.451, supports for MultiView technology for accelerated OpenGL rendering on multiple video card setup (CrossFire). The driver also allows CrossFire configurations for Radeon HD 3850 and HD 3870 video cards. The Catalyst 8.3

18422-558: The performance of a single card. The R600 family is called the Radeon HD 2000 series, with the enthusiast segment being the Radeon HD 2900 series which originally comprised the Radeon HD 2900 XT with GDDR3 memory released on May 14, and the higher-clocked GDDR4 version in early July. The mainstream and budget segment products were the Radeon HD 2600 and Radeon HD 2400 series respectively, both launched June 28, 2007. Previously there were no HD 2000 series products being offered in

18573-401: The performance segment while ATI used models from the previous generation to address that target market; this situation did not change until the release of variants of the Radeon HD 2900 series, the Radeon HD 2900 Pro and GT, which filled the gap of the performance market for a short period of time. The Radeon HD 2400 series was based on the codenamed RV610 GPU. It had 180 million transistors on

18724-471: The point-to-point chassis construction method remained in common use in industry (such as TV and hi-fi sets) into at least the late 1960s. Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards. Originally, every electronic component had wire leads , and

18875-657: The practice of branding livestock to deter theft. Images of the branding of cattle occur in ancient Egyptian tombs dating to around 2,700 BCE. Over time, purchasers realized that the brand provided information about origin as well as about ownership, and could serve as a guide to quality. Branding was adapted by farmers, potters, and traders for use on other types of goods such as pottery and ceramics. Forms of branding or proto-branding emerged spontaneously and independently throughout Africa, Asia and Europe at different times, depending on local conditions. Seals , which acted as quasi-brands, have been found on early Chinese products of

19026-407: The practice of branding objects extended to a broader range of packaging and goods offered for sale including oil , wine , cosmetics , and fish sauce and, in the 21st century, extends even further into services (such as legal , financial and medical ), political parties and people 's stage names. In the modern era, the concept of branding has expanded to include deployment by a manager of

19177-473: The presence of these simple markings does not imply that mature brand management practices operated. Scholarly studies have found evidence of branding, packaging, and labeling in antiquity. Archaeological evidence of potters' stamps has been found across the breadth of the Roman Empire and in ancient Greece . Stamps were used on bricks, pottery, and storage containers as well as on fine ceramics. Pottery marking had become commonplace in ancient Greece by

19328-646: The printed circuit as part of a radio set while working in the UK around 1936. In 1941 a multi-layer printed circuit was used in German magnetic influence naval mines . Around 1943 the United States began to use the technology on a large scale to make proximity fuzes for use in World War II. Such fuzes required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted

19479-478: The process into consumer electronics, announcing in August 1952 the adoption of "plated circuits" in home radios after six years of research and a $ 1M investment. Motorola soon began using its trademarked term for the process, PLAcir, in its consumer radio advertisements. Hallicrafters released its first "foto-etch" printed circuit product, a clock-radio, on November 1, 1952. Even as circuit boards became available,

19630-518: The producer's name. Roman glassmakers branded their works, with the name of Ennion appearing most prominently. One merchant that made good use of the titulus pictus was Umbricius Scaurus, a manufacturer of fish sauce (also known as garum ) in Pompeii, c.  35 CE . Mosaic patterns in the atrium of his house feature images of amphorae bearing his personal brand and quality claims. The mosaic depicts four different amphora, one at each corner of

19781-418: The product, the consumer lifestyle, and the endorser is important for the effectiveness of brand communication. Printed circuit board A printed circuit board ( PCB ), also called printed wiring board ( PWB ), is a medium used to connect or "wire" components to one another in a circuit . It takes the form of a laminated sandwich structure of conductive and insulating layers: each of

19932-403: The protruding wires are cut off and discarded. From the 1980s onward, small surface mount parts have been used increasingly instead of through-hole components; this has led to smaller boards for a given functionality and lower production costs, but with some additional difficulty in servicing faulty boards. In the 1990s the use of multilayer surface boards became more frequent. As a result, size

20083-441: The resin matrix, and the associated local variations in the dielectric constant, are gaining importance. The circuit-board substrates are usually dielectric composite materials. The composites contain a matrix (usually an epoxy resin ) and a reinforcement (usually a woven, sometimes nonwoven, glass fibers, sometimes even paper), and in some cases a filler is added to the resin (e.g. ceramics; titanate ceramics can be used to increase

20234-478: The same side of the board. A board may use both methods for mounting components. PCBs with only through-hole mounted components are now uncommon. Surface mounting is used for transistors , diodes , IC chips , resistors , and capacitors. Through-hole mounting may be used for some large components such as electrolytic capacitors and connectors. The first PCBs used through-hole technology , mounting electronic components by lead inserted through holes on one side of

20385-408: The simplest boards to produce is the two-layer board. It has copper on both sides that are referred to as external layers; multi layer boards sandwich additional internal layers of copper and insulation. After two-layer PCBs, the next step up is the four-layer. The four layer board adds significantly more routing options in the internal layers as compared to the two layer board, and often some portion of

20536-414: The size and weight of through-hole components, and passive components much cheaper. However, prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages, and some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents. Each trace consists of

20687-422: The substrate. Chemical etching divides the copper into separate conducting lines called tracks or circuit traces , pads for connections, vias to pass connections between layers of copper, and features such as solid conductive areas for electromagnetic shielding or other purposes. The tracks function as wires fixed in place, and are insulated from each other by air and the board substrate material. The surface of

20838-402: The term "printed circuit board" most commonly means "printed circuit assembly" (with components). The IPC preferred term for an assembled board is circuit card assembly ( CCA ), and for an assembled backplane it is backplane assembly . "Card" is another widely used informal term for a "printed circuit assembly". For example, expansion card . A PCB may be printed with a legend identifying

20989-419: The thickness and stresses the plated-through holes. Repeated soldering or other exposition to higher temperatures can cause failure of the plating, especially with thicker boards; thick boards therefore require a matrix with a high T g . The materials used determine the substrate's dielectric constant . This constant is also dependent on frequency, usually decreasing with frequency. As this constant determines

21140-418: The top of the mobility lineup, the HD 2600 XT. The half-generation update treatment had also applied to mobile products. Announced prior to CES 2008 was the Mobility Radeon HD 3000 series. Released in the first quarter of 2008, the Mobility Radeon HD 3000 series consisted of two families, the Mobility Radeon HD 3400 series and the Mobility Radeon HD 3600 series. The Mobility Radeon HD 3600 series also featured

21291-476: The trend. By the early 1900s, trade press publications, advertising agencies , and advertising experts began producing books and pamphlets exhorting manufacturers to bypass retailers and to advertise directly to consumers with strongly branded messages. Around 1900, advertising guru James Walter Thompson published a housing advertisement explaining trademark advertising. This was an early commercial explanation of what scholars now recognize as modern branding and

21442-400: The way in which consumers had started to develop relationships with their brands in a social/psychological/anthropological sense. Advertisers began to use motivational research and consumer research to gather insights into consumer purchasing. Strong branded campaigns for Chrysler and Exxon /Esso, using insights drawn from research into psychology and cultural anthropology , led to some of

21593-511: The weave pattern. Nonwoven reinforcements, or materials with low or no reinforcement, are more expensive but more suitable for some RF/analog applications. The substrates are characterized by several key parameters, chiefly thermomechanical ( glass transition temperature , tensile strength , shear strength , thermal expansion ), electrical ( dielectric constant , loss tangent , dielectric breakdown voltage , leakage current , tracking resistance ...), and others (e.g. moisture absorption ).

21744-440: The weight of copper per area (in ounce per square foot) which is easier to measure. One ounce per square foot is 1.344 mils or 34 micrometers thickness. Heavy copper is a layer exceeding three ounces of copper per ft , or approximately 0.0042 inches (4.2 mils, 105 μm) thick. Heavy copper layers are used for high current or to help dissipate heat. On the common FR-4 substrates, 1 oz copper per ft (35 μm)

21895-417: The world's oldest in continuous use. A characteristic feature of 19th-century mass-marketing was the widespread use of branding, originating with the advent of packaged goods . Industrialization moved the production of many household items, such as soap , from local communities to centralized factories . When shipping their items, the factories would literally brand their logo or company insignia on

22046-433: Was assigned to the U.S. Army. With the development of board lamination and etching techniques, this concept evolved into the standard printed circuit board fabrication process in use today. Soldering could be done automatically by passing the board over a ripple, or wave, of molten solder in a wave-soldering machine. However, the wires and holes are inefficient since drilling holes is expensive and consumes drill bits and

22197-426: Was further minimized and both flexible and rigid PCBs were incorporated in different devices. In 1995 PCB manufacturers began using microvia technology to produce High-Density Interconnect (HDI) PCBs. Recent advances in 3D printing have meant that there are several new techniques in PCB creation. 3D printed electronics (PEs) can be utilized to print items layer by layer and subsequently the item can be printed with

22348-431: Was introduced, supporting display resolutions up to 1,920×1,080, with integrated HD audio controller with 5.1-channel LPCM and AC3 encoding support. Audio is transmitted via DVI port, with specially designed DVI-to-HDMI dongle for HDMI output that carries both audio and video. All variants support CrossFireX technology. CrossFire efficiency was improved and shows performance approaching the theoretical maximum of twice

22499-448: Was rumored that some of the 1 GB GDDR4 models were manufactured using a 12" cooler borrowed from the prototype HD 2900 XTX. The HD 2900 Pro had both 256-bit and 512-bit interface options for the 512 MB versions of the card. A few AIB partners offered a black and silver cooler exclusive to the 256-bit model of the Pro. The Radeon HD 2900 GT was a 240 Stream Processor variant clocked the same as

22650-435: Was the brand name. With the rise of mass media in the early 20th century, companies adopted techniques that allowed their messages to stand out. Slogans , mascots , and jingles began to appear on radio in the 1920s and in early television in the 1930s . Soap manufacturers sponsored many of the earliest radio drama series, and the genre became known as soap opera . By the 1940s, manufacturers began to recognize

22801-444: Was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron . If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a product or company, so that "brand" now suggests the values and promises that a consumer may perceive and buy into. Over time,
