Abstract

PURPOSE:To protect a circuit conductor of a printed wiring board against heating so as to prevent an erroneous operation of the printed wiring plate due to heating by a method wherein a heat dissipating film is provided to the circuit conductor and an insulating film is provided as plural heat dissipating windows are interspersed in a lengthwise direction on the heat dissipating film. CONSTITUTION:A heat dissipating film 12 is provided to the surface of a circuit conductor 11. An insulating film 14 is formed as plural circular windows 15 are arranged so as to be interspersed along a lengthwise direction on the film 12 formed on the surface of the conductor 11. The windows 15 are circles, ellipses, or triangles in shape. Then, heat generated in operation is actively dissipated through the film 12 formed on the upper side of the conductor 11. The windows 15 enables the decrease of the dissipating effect due to the film 14 to be prevented. By these processes, the conductor 11 is prevented from being heated, and thus the erroneous operation caused by heating can be prevented.
