Patent ID: 8072759

Claim:
An electronic device comprising: a housing; a printed circuit board contained in the housing; and a surface mount part mounted on the printed circuit board, the surface mount part comprising, a substrate comprising a first surface facing the printed circuit board, and a second surface opposite to the first surface; a plurality of connection terminals arranged on the first surface of the substrate and soldered to the printed circuit board; a chip mounted on the second surface of the substrate; a cooler arranged to face the second surface of the substrate and cover the chip, the cooler being thermally connected to the chip; and reinforcing modules configured to reinforce solder joint portions between the connection terminals and the printed circuit board, the reinforcing modules being structured by providing an adhesive across an outer peripheral edge of the substrate and the printed circuit board and comprising spacer portions interposed between the second surface of the substrate and the cooler and configured to support the cooler, wherein the cooler comprises a first region facing the chip and a second region around the first region and facing the second surface of the substrate, and the spacer portions maintain a gap between the second region of the cooler and the substrate.
