It depends........8-)

Push down fixtures need to be carefully designed in order to balance the
localized probe forces. If they are badly designed the results can indeed
have adverse impacts on reliability.

Subject: [TN] PCBA Test

Hello Technet,

 

I'm looking forward your invaluable input concerning ICT test on PCB that
has thickness of 1.2mm (0.0472") in total. What are the issues that we might
run into if the PCB (thickness 1.2mm) is subjected to ICT using press down
fixture instead of vacuum fixture? In term of reliability and repeatability.

 

Thanks,

Gobi
