METHOD FOR COMBINED THROUGH-HOLE PLATING AND VIA FILLING

The present invention relates to a method for copper electroplating in the manufacture of printed circuit boards, IC substrates and the like. Said method is suitable for a combined conformal through-hole filling and filling of blind micro vias. The method utilizes a metal redox system and pulse reve...
