The systems have increased test throughput by up to 75% over the original testers. Also, result reporting is easier thanks to a compact database that stores all test data. Lifeline Systems provides ...

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。

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 ...

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 ...

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 ...
