MAKING METHOD OF METAL CORE PCB BY HOLE PUNCHING AND METAL CORE PCB THEREBY

摘要

The present invention relates to a method of manufacturing a metal core PCB by hole punching and a metal core PCB thereof. The method of manufacturing the metal core PCB, in which a core layer is formed by inserting the metal core into a resin layer of the PCB including a resin layer and a metallic thin film formed at a surface thereof, includes forming a guide hole at an edge of the metallic plate; forming a plurality of non-contact holes at an inner part of the metallic plate having a guide hole through a pouching work; removing bur formed at the edge of the non-contact hole of the metallic plate through the punching work; preparing a metallic ore source plate having the metallic plate serving as a metallic core layer in the resin layer by laminating the metallic plate having a plurality of the non-contact holes without the bur and the inner resin layer and the surficial metallic thin film; and forming a contact hole and a non-contact hole in matching with the non-contact hole of the metallic core source plate having the core layer, thereby improving the production rate of the PCB and the productivity of the PCB to reduce the failure rate.
