Skived fin heat sink is made of a piece of base material (aluminum or copper) .Under the mechanical action, the tilting Angle of the tool is controlled by the customized tool and the program written, the  base material  is precisely cut from the top by a shovel-tooth tool, and folded back to a position perpendicular to the base, and repeated at a certain spacing to form fins. Skived Fin Process can make the Fins thinner and denser, increasing the radiator area per unit volume, thereby improving heat dissipation efficiency.
