NOVELTY - The utility model claims an alumina ceramic substrate for durable packaging, comprising a main body, a reflecting cup, a buffer layer, an upper line layer, a lower line layer, an upper graphene heat conducting layer and a lower graphene heat conducting layer; the upper and lower surface of the main body is formed with a conductive hole and a plurality of heat conducting holes, the conductive hole is filled with metal to form a conductive column, each heat conducting hole is filled with graphene material to form a heat conducting column. The main body is designed to be composed of a main body comprising a base layer, an upper alumina coating layer, a titanium-tungsten coating layer, lower alumina coating layer and lower titanium tungsten coating layer, so that each layer structure is connected stably, it is not easy to fall off, at the same time, it is matched with a buffer layer to play a role of buffering, it effectively improves the durability of the product, prolongs the service life of the product, and is provided with a heat conducting column by matching, upper graphene heat conducting layer and lower graphene heat conducting layer, the heat can be quickly derived, realizing better radiating effect.
