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 ...

STOCKHOLM, SWEDEN – Mycronic’s Global Technologies division has acquired ETZ, a Germany-based manufacturer of test probes used in electrical testing of bare printed circuit boards.

In-circuit test can exercise components individually. Boundary-scan test can evaluate components as well as interconnects. Functional test can test for faults that may have escaped other stages while ...

For testing PCBs, test engineers have a variety of options ranging from venerable in-circuit testers and flying probers to functional testers and the latest in embedded-instrument technology.

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。

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 ...

The unit is an integrated package of high specification instrumentation controlled by sophisticated but easy to use software. The hardware is installed in a transportable case that also contains a ...

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 ...
