摘要:
A selective metallization process particularly suited for making printed circuit boards comprises the step of treating a substrate having a negative mask thereon with a reactant, e.g., acetic acid, which modifies the surface of the mask without affecting the substrate so as to remove or prevent an active catalytic layer from remaining on the surface of the mask thereby preventing electroless plating on the mask.
