Abstract:
1. A support structure of an electronic device, comprising: an integrated circuit; a printed circuit board (PCB) to which the integrated circuit is mounted, the PCB including a substrate having first and second opposite major surfaces, and a through-hole, the first surface having an integrated circuit (IC) mounting area having a shape conforming to that of the integrated circuit and occupied by the integrated circuit, and the through-hole open to the first surface within the IC mounting area; and a base supporting the printed circuit board, the base having a surface that faces and is spaced from the second surface of the PCB, and the base including a heat dissipation column protruding from said surface of the base into contact with an inner circumferential wall of the PCB that defines the through-hole of the substrate of the PCB such that the heat dissipation column contacts the PCB at a location directly opposite the IC mounting area, whereby the heat dissipation column will transfer heat generated by the integrated circuit to the base.
