We found a PCBA performance have insertion loss at the functional test process. We did some analysis and conclude the main root cause is from the PCB performance. What is the critical parameter in PCB will cause a failure in PCBA frequency performan

Trying to get a sense of the push-pull going on between designers and manufacturers on the subject of 'one test point per net'. Getting a feeling like the new paradigm is doing all of the electrical tests as functional at EOL and relying almost comp

Depends on what sort of outfit you are working for, and what you are building. A lot of CEMs are doing Flying Probe or ICT on the boards ahead of investing time building into units or adding parts that prevent access to rework. We have a combination

You will have to be more specific about your boards and process to get any help. There are many different types of in circuit tests and functional tests throughout the manufacturing process. The nature of these tests depend on board function. Sinc
