Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p

. Otherwise the paint will peel off quickly. Conformal coating logic is the same as painting. To make matters worse, the coating is often semi-permeable, and moisture can get in and seep into the flux residue and cause corrosion
