COMPONENT MOUNTING BOARD, PROCESS FOR PRODUCING THE BOARD, AND PROCESS FOR PRODUCING THE MODULE

摘要

Characterized in that a mask film (3) having desired openings (2) are coated onto a metal wiring plate (1). According to this, an insulating base body and a resist layer making a thick base as in a conventional substrate can be omitted. In addition, by bending a terminal part (T) of the metal wiring plate (1), a connecting terminal replaceable with a connecter terminal to another substrate can be also machined integrally and the connecter terminal can be made unnecessary, so that an inexpensive parts-packaging substrate can be provided.
