Ok so.... I have a boss who thinks there is nothing wrong with stacking completed boards smt&thru in totes and submitting them to QA like this. I mean piled upon one another in a tote. Now... it has fallen on me to try to explain in a convincing mann

Wow, you're using the Surface Mount Adhesive for mechanical vibration? I've never heard of SMT adhesive being used for things other than holding the components in place before wave solder. Does it work for mechanical purposes? Glue/Wave is a proce

Has anyone experienced a problem with conformal coating adhesion to IS-410 boards? We are having problems with one suppliers boards. IS-410 boards from other suppliers are fine and all FR-4 boards that I have looked at are fine. We are using Conap

We expect to see a copper shadow along the edge of pads when soldering boards with organic solderability protection [OSP]. IPC-A-610 has defined this as acceptable for years. During early reflow stages, the flux in paste dissolves the OSP where ther

Are these shorts occuring after reflow, or are they shorted on the incoming boards before stuffing? If the latter, is the fabricator doing electrical test? How are these boards getting past their electrical test? Especially if multilayer, there's
