What about when debugging the board I recently saw a case where we damaged a board between - 5-10 cycles of the fixture It's a catch 22 - where you need high force probes to breal the OSP - but the copper is hard surface, not like the solder HASL a

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

If it passes functional test it is a good board.

Hello. I would like to know the difference (if any) between water soluble flux and test socket cleaners (e.g. for Burn-In Board test sockets). As far as I know, they both remove oxides (tin & copper) with an activator, solvent and surfactants. Tha

is there flux on the board? are you probing a test point or a soldered pad? is the probe hitting the right spot?

It depends on your product application requirement, normally should not drop off board for automotive. Even the dropped board pass function test in plant, it will have problem in its working environment.

Mantis: Kenny reflows paste on [wave solders] all via, not just the test via, to plug the via and provide for a pressure seal between the board and the test fixture. Beyond that, since solder is softer than copper [and fills the hole better], solde

i designed a new product; i want to produce it in china, so they requested the ICT to be done; i have 03 questions if some one can help me on: 1� is it mondatory to test all components and paths in the PCBA; and check all soldering joints? 2� testing

Has anyone had experiences of ICT test fixtures actually damaging the PCB boards - typically when they have moved away from HASL finish to OSP. I would also like to hear more about any specific issues seen at ICT for non HASL pcb finishes thanks -

100% visual inspection. If we test, then we retest (assuming this is a completed board). Also, if there is an accelerometer on board, we argue about whether or not we should replace it by default.
