Abstract

PURPOSE:To reduce the effect of a thermal load onto an electric part by placing optical and electric parts respectively via a solder layer on the comparatively high and low parts of the thermal conductivity of a circuit board and soldering both parts on the board by heating the board by a heating plate. CONSTITUTION:A substrate 1 is composed of the metal sheet 2 of high heat conductivity and the glass fiber cored lamination sheet 3 of low heat conductivity. And optical parts 5, 5 are placed on the metal sheet 2 of high heat conductivity via a solder layer 4. Also, electric parts 6, 6... are placed on the lamination sheet 3 of low heat conductivity via solder layers 4, 4... when the substrate 1 is heated by a heating plate 7 in this state, the heating curve of the optical part 5 and electric part 6 can be made about the same due to the difference in the heat conductivities, the time reaching the soldering temp. of both parts 5, 6 becomes about the same and the thermal effect onto the electric part 6 can be reduced.
