NOVELTY - The utility model claims a universal UV-encapsulated ceramic substrate, comprising a ceramic body and a metal dam; the upper surface of the ceramic body is concavely provided with a first recess for embedding the UV wafer, the inner wall surface of the first recess is completely coated with graphene coating layer, the lower surface of the ceramic body is concavely provided with a second recess, the second recess is filled with graphene material to form a radiating layer, and the inner bottom surface of the second recess and the inner bottom surface of the first recess are formed with a heat conducting hole. by setting the first recess, the UV wafer can realize embedded mounting, stable mounting, not easy to fall off, at the same time, by matching set in the second recess filling material graphene form a radiating layer, filling graphene material in the heat conducting hole to form a heat conducting column, and the inner wall surface of the first recess is completely coated with graphene coating, using the graphene can be used for fast heat conducting, realizing better radiating effect, the use requirement of the satisfy.
