PCBA fail functional test due to frequency drift | 14 October, 2009

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 performance?
