What's the point of such a test? * If you are operating a board in an environment that keeps the board at a temperature that is close to causing delamination, why not design a board that can tolerate such an operating environment, rather than contin

Is there a test to check for delamination on a pcb? We are looking at new board houses and along with our standard solderability tests my boss wants to test for delamination. thanks, pr

50% chance his boss has heard of (or maybe even one time seen) delamination and wants to be sure they don't have that problem. His boss probably felt a need to specify a test and that was one he had heard of. Personally I would recomend find a way f

Do you have a cube down the hall from me? I think it's already been forgotten, but when blindsided by these requests one has to do SOMETHING! I blasted one in reflow and did a 7 second solder bath dip with another and took pictures, nobody has asked

50% of seeing it in a single pass. The only time we do this is if we have a board off the line that has delaminated. We'll run a sample of boards through bare to confirm that we have a bad batch. Even if we see no failures on the bare boards, we'l

Pr. I agree with some of the above responses. if you are seeing Delam issues with incoming PCB's the following should be check. 1) Check the OEM Print to what Material they are calling out to be manufactured with. 2) If they are calling out for S
