Interesting, A north American Solder resist firm stated the same thing to a degree. They said altering the resist cure profile can effectively change the surface energy thus making the surface more conducive to conformal coat adhesion. At in coming

Emilio: Several factors you need to take into account and your process parameters will depend on: Solder Alloy, Is there any Fine Pitch?; BGA?; Smaller chip size?. Tipically you should go for controls in: Solder Temperature and viscosity; blade and s
