A HIGH HEAT CONDUCTIVE CIRCUIT SUBSTRATE

摘要

A high heat conductive circuit substrate (10) includes: a metal substrate (20), an insulating layer (30) which is formed on the surface of the metal substrate (20), a first dielectric layer (40) which is formed on the surface of the insulating layer (30), a conductive layer (50) which is formed on the surface of the first dielectric layer (40). The conductive layer (50) is made up of a conductive media layer (52) and a main conductive layer (54).
