ABSTRACT:
A printed circuit board includes a wiring pattern formed on an insulating board according to a predetermined electric circuit, and a cover member covering a portion of the wiring pattern used as a contact, the cover member being formed of an electrically conductive and non-solderable material. Due to the presence of the covering member, the wiring pattern portion is not covered with solder when the printed circuit board is subjected to dip soldering to attach various electric components to the printed circuit board. Since the covering member is electrically conductive, the wiring pattern portion can readily be used as a contact when the dip soldering is completed.
