A METHOD OF MANUFACTURING THE HIGH HEAT CONDUCTIVE CIRCUIT SUBSTRATE

摘要

A method of manufacturing the high heat conductive circuit substrate (50) includes the following steps: proving a metal substrate (10); forming an insulating layer (20) on the surface of the metal substrate (10), the insulating layer (20) making up the oxide of the metal substrate (10); forming a medium layer (30) on the surface of the insulating layer (20); forming a main conductive layer (40) on the surface of the medium layer (30).
