Abstract:
1. A method for manufacturing a multilayer printed circuit board, comprising: providing a core substrate having a penetrating-hole for a through-hole conductor structure; forming an electroless plated film on a surface of the core substrate and an inner wall surface of the penetrating-hole; electrolytically plating the core substrate while moving with respect to the surface of the core substrate an insulating member in contact with the surface of the core substrate such that an electrolytic plated film is formed on the electroless plated film, an opening space inside the penetrating-hole is filled with an electrolytic material, and a through-hole conductor structure is formed in the penetrating-hole; forming an etching resist having an opening pattern on the electrolytic plated film; and removing an exposed pattern of the electrolytic plated film exposed by the opening pattern of the etching resist and a pattern of the electroless plated film under the exposed pattern of the electrolytic plated film such that a conductor circuit is formed on the surface of the core substrate.
