NOVELTY - The utility model claims an ultra-thin high precision ultra-wear resistant heat conducting sheet, comprising a heat conducting sheet base body made of aluminium alloy die-casting, the outer surface of the heat conducting sheet base body is coated with a layer of aluminium oxide film layer, further comprising depositing a graphite heat conducting layer on the heat conducting substrate, depositing a metal deposition layer on the graphite heat conducting layer. The technical solution by depositing a graphite heat conducting layer or graphene heat conducting layer on the aluminium alloy heat conducting sheet substrate, using the graphite heat conducting layer and graphene heat conducting layer of the particle heat transfer direction consistency, using the heat of the heating part to quickly lead out, improving the radiating efficiency; and the wear-resisting property is improved by the aluminium oxide film layer under the condition of ensuring the heat conducting efficiency. Through the conventional deposition technology, the graphite or graphene and metal particles are deposited on the heat conducting sheet base body, so that the thickness of the heat conducting sheet is greatly reduced, and it is suitable for heat dissipation of ultra-thin electronic product or other corresponding products.
