PRINTED-CIRCUIT BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a printed-circuit board capable of improving radiation performance and forming a fine circuit on a substrate surface layer.SOLUTION: A printed-circuit board comprises: a core substrate 2 in which a wiring pattern 4 is formed on at least one surface of an insulating plate 1; an insulating resin layer 21a laminated on a surface of the core substrate 2; a housing unit 11 which is a through-hole penetrating the core substrate 2 and the insulating resin layer 21a; and a metal small piece 40 housed in the housing unit 11. The metal small piece 40 is fixed by filling a metal small piece fixing resin 13 with insulation quality in the gap between an inner peripheral surface of the housing unit 11 and the metal small piece 40.
