ABSTRACT:
Process for the planting of through-holes in an epoxy printed circuit board base material in the manufacture of printed circuit boards. The treatment process is designed to increase adhesion between the epoxy board material and a subsequently deposited metal plate. The process is characterized, in part, by the use of an activated permanganate solution.
