发明名称 Heat sink for plastic ball grid array on IC chip surface has antioxidant coating on protruding body mounted on chip surface to form an elastic connecting structure using material adhesion
摘要 The heat sink has a protruding body on its inside, a coating of antioxidant deposited on the protruding body, a substrate with an earth connection point connected to a heat sink connection finger, a silver adhesive connecting the chip to the substrate and heated to mount the chip on the substrate and an elastic, heat-conducting adhesive deposited onto the surface of the protruding body or chip. The protruding body is connected to the chip surface using a joining arrangement and is mounted on the chip surface to form an elastic connecting body structure using a material adhesive process.
