Abstract
An electric circuit board has a plurality of conductive pads on a base plate for connection with conductive pins of an electric device such as a thermal head of a facsimile machine. Protective parts are formed on the base plate at the right side of the rightmost conductive pad and at the left side of the leftmost conductive pad. The conductive pads and the conductive pins are soldered by solders heated and melted by a light beam. The protective parts protect the base plate from being burnt by the light beam even when the light beam is projected transversely across the pads from the right side of the rightmost pad to the left side of the leftmost pad.
