Donner Company has positioned itself well within both the small volume‚ customized (contract) printed circuit boards market as well as the large volume‚ generic (captive) printed circuit boards market. Large electronic firms (AT&T‚ IBM) produced their components in captive shops‚ while smaller sized companies‚ or when large and small quantities of simple technology or fast turn-around prototype boards were required‚ these requests usually are fulfilled by contract shops. With 750 competitors in the

value. The range of resistance provided‚ the maximum resolution‚ and the accuracy characterize the box. For example‚ one box offers resistances from 0 to 24 mega ohms‚ maximum resolution 0.1 ohm‚ accuracy 0.1%. • Breadboard A breadboard (proto board) is a construction base for prototyping of electronics. The term is commonly used to refer to solderless breadboard (plugboard). Because the solderless breadboard does not require soldering‚ it is reusable. This makes it easy

ay from printed circuit boards (PCBs) that used copper containing thick- lm pastes on rigid substrates‚ which were patterned using a two-step masking and etching process. This process resulted in a surfeit of waste and was expensive due to laborintensive processing of the nal device. By contrast‚ conductive inks are now available that use existing printing technologies such as screen‚ gravure‚ exographic‚ offset‚ and inkjet to print conductive traces directly onto rigid and exible substrates relatively

consider SI in their designs. Modern digital circuits can operate up to gigahertz frequencies with rise times in the order of fifty picoseconds. At these speeds‚ a carelessly designed PCB trace only needs to be an inch or so long before it radiates. Radiating traces create voltage‚ timing and interference problems not only on that line‚ but also across the entire board and even across adjacent boards. The problem is even more critical with mixed-signal circuits. For example‚ consider a system that relies

In FY09‚ 86 percent of Cisco printed circuit boards were produced without washing‚ and we have committed to completely eliminating water washing of printed circuit boards by early FY10. Cisco estimates that the elimination of water wash for this remaining 14 percent of our circuit boards will save 20 million gallons of water and over $1 million
