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

We have recently had a jig get caught in the chain of the flowsolder machine, causing the board to delaminate, is there any hard and fast rules as to if the area needs evacuating due to fumes, and if the air quality has to be checked before allowing

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

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

I ma trying to get some information on possible causes and screening tests for PCB delamination. Is the main cause moisture absorption of PCB material or entrapped chemicals and or air in innerlayers that expand when expsoed to subsequent reflow and

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

Wha, Nellie!!! Delamination & Blistering IPC-A-600D Although it may occasionally occur because of a severe process breakdown, delamination and blistering occurs as a result of an inherent weakness of the material. Either condition represents a brea

I love this!!! Two whizzettes with the same information and they spin-off in two different directions. Gad this is great!!! Delamination is a pretty broad topic, but that you have a problem with two suppliers makes me think the delamination is cau

Hi, I have a problem I've never seen before so I hope someone here can help. A recent batch of PCBs arrived where the copper lands delaminate with a small pull. Normally you have to pull pretty hard and the whole land comes off the substrate. These
