The limited access afforded to circuit nodes by PCBs densely populated with tiny components seriously challenges traditional PCB test strategies. But while optical and x-ray inspection can help fill ...

PCBs must survive impact, flexing and thermal cycles so how can mechanical testing be used to test for vulnerabilities?

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 ...

Test Coupon，是用来以 TDR (Time Domain Reflectometer 时域反射计) 来测量所生产的 PCB 的特性阻抗是否满足设计的要求，一般要控制的阻抗有单端线和差分对两种情况，所以 test coupon 上的走线线宽和线距(有差分对时)要与所要控制的线一样，最重要的是测量时接地点的位置。

As test targets shrink, the benefits of socketless probing technology grow. As technology advances, more and more electronic components that do bigger and better things are hitting the market. At the ...

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 where ...

Integration enables companies to prepare designs and implement robust test strategies early in the PCB assembly manufacturing process, enabling earlier defect detection, reduced costs, accelerated ...

A next-generation board-test system combines structural, parametric, high-speed interconnect, and functional testing to ...

Test engineers have a variety of options for testing printed-circuit boards—ranging from in-circuit testers to the latest in embedded-instrument technology. Despite the decline of PCB physical access ...
