PURPOSE:To simplify a mounting method, and to radiate heat excellently by directly arranging the heavy electric parts to a printed board while giving mechanical strength to a chassis through a supporter. CONSTITUTION:The heavy electric part 3 is disposed on the printed board 1, striding across a knockout section 7, and the connecting terminals 8 are inserted into the board 1, and soldered. The knockout section 7 positioned at a lower section of the parts 3 is removed, a through-hole 10 is formed and a lower section of the parts 3 is opened. The board 1 is fixed to the chassis 4 by means of a fixture. Accordingly, since the weight of the part 3 through soldering is applied to the chassis 4 through the supporter, the board 1 is protected from vibration and an impact, and heat can be radiated excellently. |
