ABSTRACT:
Substantially nonconductive or semiconductive surfaces of through holes can be electroplated directly, without an intervening non-electrolytic metallization, by a stepwise process which includes the application to the through holes of a polyelectrolyte surfactant in solution in combination with the application of a conductive metal containing material.
