Abstract:
1. An assembly method for a Chip On Board semiconductor device having a semiconductor die having a heat sink cap abutting a portion of a top surface of a substrate including: placing a compliant adhesive-filled gel silicone elastomer between a portion of an upper surface of the semiconductor die and a portion of a lower surface of the heat sink cap; the heat sink cap surrounding the semiconductor die, the heat sink cap having a side wall having a hole therein; pressing the semiconductor die into the heat sink cap to engage the semiconductor die and heat sink cap in compliant removable adhesion and for causing the edge of the heat sink cap to abut the substrate; and injecting an encapsulant into the heat sink cap engaging at least interior portions of the heat sink cap, at least portions of the semiconductor die, at least portions of the top surface of the substrate, and at least portions of the compliant adhesive-filled gel silicone elastomer.
