In-circuit test (ICT) systems have been the leaders in using electrical means to look for structural defects in PCBs. They employ bed-of-nails fixtures to provide electrical access to as many as 7000 ...

This article, devoted to the importance of PCB checks, shines a light on the most popular PCB testing methods and their application in circuit-board design and production.

Test engineers struggle to find the optimum balance between printed-circuit-board (PCB) cost and test coverage. Low coverage leads to excessive field returns, warranty replacements, and even lawsuits.

Designing circuit boards for high speed applications requires special considerations. This you already know, but what exactly do you need to do differently from common board layout? Building on whe… ...
