Hi TechNet, I have been asked what chemical(s) would be required to remove cured nomenclature ink (also known as silkscreen) from a bare board without damaging the board itself. I am assuming it is an epoxy ink, but I do not know the exact formulation. Any input is appreciated. I should know the exact formulation of the applied nomenclature ink tomorrow, but thought that maybe there is a generic answer.
