PCB AND METHOD OF MANUFACTURING THEREOF

摘要

A PCB and a manufacturing method thereof are provided to enhance a heat-radiating effect by interposing a heat-radiating coating layer between an insulating layer and a heat-radiating layer to make smooth the heat transfer between the insulating layer and the heat-radiating layer. A PCB includes a heat-radiating layer(20), a pair of insulating layers(10), a predetermined circuit pattern(12), an interlayer conduction unit, and a heat-radiating coating layer(30). The pair of insulating layers are laminated with interposing the heat-radiating layer therebetween. The predetermined circuit pattern is formed on the insulating layer. The interlayer conduction unit electrically connects the upper and the lower parts of the insulating layer by passing through the insulating layer. The heat-radiating coating layers are formed on both sides of the heat-radiating layer respectively, and has a DLC(Diamond Like Carbon).
