description Process for at least partially dissolving a copper oxide surface layer by contacting the surface layer with one or more copper oxide dissolving compounds. When used in the manufacture of a multilayer printed circuit board, the process improves adhesion between board layers, reduces or eliminates localized delamination of a multilayer board that occurs during through-hole drilling, and eliminates or substantially reduces the occurrence of pink ring.
