METHOD FOR MANUFACTURING HEAT-DISSIPATING SUBSTRATE

摘要

PURPOSE: A method for manufacturing a heat radiation substrate is provided to simplify process by welding a substrate and a heat radiation module through ion junction and to obtain junction uniformity through the ion junction. CONSTITUTION: An insulating layer(20) is formed by anodizing the surface of a metal core(10). The metal core is a base for forming a heat radiation substrate. A heat radiation module(30) formed into metal is attached to one side of the insulating layer. The heat radiation module and the metal core are ion-welded. The heat radiation module and the metal core are same material. A metal layer is formed on the metal core. A circuit pattern is formed on the metal layer.
