Abstract
PURPOSE: To improve reliability of through hole, by superposing an insulating plate previously hardened on a metal plate to form a punched hole in the metal plate using stamping and by sticking through a prepreg a metallic foil on both of the surfaces of the metal plate in which an insulating plate formed in the same shape as the punched hole in the stamping is inserted into the punched hole.
CONSTITUTION: An insulating plate 2 of thermosetting resin previously hardened is superposed on a metal plate 1 to form a punched hole 7 in the metal plate 1 using stamping. An insulating plate 2' which is formed in the same shape as the punched hole 7 in the stamping is then inserted into the punched hole 7 of the metal plate 1. Next, a metallic foil 4 is superposed on both of the surfaces of the metal plate l through a prepreg 3 into which the insulating plate 2' is inserted, and is then impression-molded under pressurization and heating condition to make these members in one body. In this resulting core inserted metallic laminate 8, a hole 5 for through hole is formed in the position into which the insulating plate 2' is inserted, and then a plating layer 6 for continuity between circuits on both of the surfaces is deposited on the inwall of the hole 5 for through hole, or electrically conductive material is filled in the hole 5 for through hole, thereby the continuity between both of the surfaces of the laminate 8 being established. Since the inwall of the hole 5 for through hole has been already insulated without performing special treatments, reliability of through hole can be highly improved.
