Bob, I've heard that many WSM manufacturers are not providing warranties for stainless steel solder pots that are holding SN100 because they are not completely confident that the SN100C alloy is non-destructive to the pot. fct�s own webpage states

I don't believe I have ever seen a non-destructive test for "Black Pad" that I could take back to a Fab house and collect monetary losses with... But if this test method actually does hold merit then collect away. I would like to know how this metho

Joris We don�t know the maximum period to store the boards without having problems with blowholes. Too many variables to determine. We prefer to just fix the problem, but understand that you have stock that you need to build-down. Determining mois
