Seriously, OSP?, change the board finish, you are the OEM, correct? You have the power! Also, as another poster mentioned, high force applied at ICT ( possibily to cut through the OSP goop ?!? ) could be warping the board enough to crack the joints.

Yes, sure. In fact in some applications ICT is coming back. Mainly due to the fact that more and more SMT discrete components have no markings, so AOI cannot tell you if you have the correct value on the PCB. Fixed pin or flying probe ICT is a valuab

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

Q1.� is it mondatory to test all components and paths in the PCBA; and check all soldering joints? A1. Nothing is mandatory. You do ICT to prove some component functionality and check manufacturing process. ICT test coverage is driven by factors i

Is this a single sided or double sided board? We run the first side flat on the oven belt this keeps the board flat for the second side assembly. If the board warps during the second reflow process we will make a support fixture to carry the PCBA

I'm probably not telling you anything you don't already know, but a technique that's worked very well in the past for me is to methodically step through every part of the process and observe your boards being built, or take a scrap or simulated one a
