Abstract
A method for manufacturing a heat sink includes steps of: preparing a metallic belt; providing a spraying device for spraying a metallic coating layer on one surface of the metallic belt; providing a stamping device for blanking the metallic belt to form a heat-dissipating fin; and stacking a plurality of heat-dissipating fins to form the heat sink. In this way, the heat-dissipating area and efficiency of the heat sink can be increased. The stability and soldering ability of different materials can be improved.
