Abstract

PURPOSE:To reduce the damage of parts which might be produced owing to any short-circuit, for improvement of the qualities and costs of those parts by forming a conductive foil part corresponding to a terminal to be soldered later into a size larger than in another conductive foil part corresponding to a terminal to be soldered first. CONSTITUTION:A printed wiring board 1 includes terminal holes 3, 3,... drilled therethrough along the arrow 6 indicative of the direction where soldering is performed, into which holes terminals 9a-9f of electronic parts 8 are inserted. Substantially, circular conductive foil parts 4a to 4e are formed around the terminal holes 3, 3,..., and a conductive foil part 4f' located at the last of those parts in the direction of the soldering is formed to be larger in its area in the opposite direction to the arrow 6 and to be substantially circular-shaped eccentrically with respect to the terminal hole 3. Automated soldering of the printed wiring board 1 causes the printed wiring board 1 to be moved as shown by the arrow 6, and a soldered portion between the backward terminal 9f and the conductive foil part 4f' having the larger area absorbs solder among the forward terminals owing to the action of surface tension and is made larger than the other portions as shown by solfer 12 of the same portion to prevent the forward terminals to be short-circuitted.
