Abstract
Abstract An electronic device comprises a housing made of a polycarbonate resin, and a novel double-sided printed circuit board. The printed circuit board has one side embedded in the housing, and the other side exposed to the interior of the housing. A plurality of refractory electronic components are mounted onto one side of the printed circuit board and include a resistor and a capacitor. A plurality of lower refractory electronic components are mounted onto the other side of the housing and include a semiconductor integrated circuit, and a transformer. Preferably, an insulating layer is applied to cover the one side of the printed circuit board and the refractory electronic components. Also, a metal layer is applied to cover the insulating layer and the inner surface of the housing.
