| | We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not

Hi all, just wondering what type of brushes you all are using to manually touch up/apply your conformal coatings? We use an solvent based acrylic and do minor touch ups as they are processed. Occasionally we will have a bristle or two come off the

Has anyone ever encountered contaminants from the immersion silver process, whether it be from the board house or not...as it relates to conformal coating. The failure mode is severe de-wetting of acrylic conformal coating. All over solver resist, to

Thanks for the reply. I didnt consider this too peculiar a situation however, since pretty much anyone who coats boards with a thin material like acrylic prob has come across this. Maybe its time to invest in some machine upgrades! Thanks
