What masking tape can people recommend for masking the board when conformal coating. I am using a PVA autocoat machine and humiseal 1B31. Current tape, is leaving residue on board when used to hold link wires down whilst glue cures and also when used

Urethane Coating (1A33)

Electronics Forum | Mon Aug 25 14:55:51 EDT 2008 | grics

I have a question for the manufacturing masters... We are going to start running test trials/DOE of a Urethane Coating (Humiseal 1A33) and I am not sure what to expect. From what I understand, urethane coating is pretty difficult to work. It is supp
