Abstract

The present invention is directed to a process for manufacturing multilayer printed circuit boards which is capable of simultaneous via hole filling and formation of conductor circuit and via holes of good crystallinity, and by which uniform deposition can be constructed on a substrate and high-density wiring and highly reliable conductor connections can be realized without annealing.
