Abstract
The present invention is directed to a process of a method for the full metallization of thru-holes in a polymer structure comprising the steps of applying a film-forming amount of a conductive polymer-metal composite paste to a metal cathode; bonding a patterned polymer structure to said paste; subjecting said polymer structure to an electrolytic plating bath for a time sufficient to fully metallize thru-hole surfaces in said patterned polymer structure and removing the structure from the cathode assembly. The fully metallized thru-hole polymer structure can then be cleaned and polished to produce a finished product.
