Tom: Once again - why are you using solvent based conformal coating. 1B31 is OK as a CC but it contains Toluene and MEK!! It is only 35% solids which means you are trying to get rid of 65% solvent. If you must use it due to customers requirement then

@tommyg_fla According to the TDS the recommended coating thickness for Humiseal 1B31 is only 1-3 mils so if I had to guess I would say your issue might be that you're re-coating over the first pass too soon. All the solvent hasn't evaporated and the

I'm working on bringing up a new conformal coat process/workcenter and have a few questions I'm hoping someone might have experience with. Right now we're manually spraying both coating materials (1B31 and 1A33 from Humiseal) using HVLP guns. I run

We currently have an assembly that we have to mask the surface of several (24)SMT components where thermal compound is applied at a latter operation. These component packages vary from BGA's to QFP's. After the thermal compound is applied the PWA is
