Leiterplatte und elektronisches Bauteil

摘要

A base material in which a base insulating layer (1) and a metallic layer are laminated is prepared. The metallic layer is processed into a predetermined pattern to form conductor patterns including terminal parts (2t). A hole (13h) is formed in a region under a predetermined terminal part (2t) where the base insulating layer is formed by directing a laser beam from below. A reinforcing board (4) having a through hole (4h) is attached to the lower surface of the base insulating layer (1) by a sheet-like adhesive (3B) having a through hole (13h), with the holes being aligned with one another. An opening space (TH) formed by the holes is filled with metallic paste by screen printing. In this way, a printed circuit board is fabricated. An electronic component is mounted on this printed circuit board.
