▎ 摘  要

NOVELTY - The utility model graphene a radiating copper-clad ceramic circuit board, comprising a lower ceramic layer and an upper ceramic layer; the lower surface of the lower ceramic layer is concavely provided with a plurality of first recesses matched with the electronic device, the inner wall of each first recess is completely covered to form a first coating graphene the upper ceramic layer is overlapped on the lower ceramic layer, between the upper ceramic layer and the lower ceramic layer is clamped with graphene radiating layer and a plurality of conductive circuit, the graphene layer is integrally connected with each first heat conducting column; by setting each recess, so that each electronic device can realize embedded mounting, mounting is stable, not easy to fall off, and the electronic device is installed, the whole thickness of the circuit board is small, the occupied space is not large, good for subsequent installation of the circuit board, at the same time, by matching graphene the radiating layer, a heat conducting column and graphene coating, using the graphene to carry out fast heat conducting, realizing better radiating effect, the need of satisfy.
