Design companies often work with multiple PCB fabricators and each fabricator may have a different set of DFM rules. It is a customary practice followed by design companies to create a common denominator rule set that can be applied to all fabricators. This process is time-consuming, inefficient,...
Vias are present in every design (except maybe some lead frames and the very rare single-layer substrate). Where they are placed, and how many there are, will depend on a slew of factors, though, as we know. There are different situations and reasons...
Backplane-Manufacturing-IntroductionPPT课件 October14,2005 1 BackplaneApplication 1.FunctionIntroduction ❖背板是PCB中具有专业化性质的特殊产品，它的主要功能就是提供一个系统的连接支持，使得各种PCB板通过它实现彼此之间的互联互通。一般情况下，它被放置在机框机架内，牢牢固定在其中，而各类PCB板，则通过各种连接...
