Patent abstract
A highly reliable printed circuit board which is capable of preventing a short circuit between traces from being caused by a solder bridge formed by excess solder. The printed circuit board has a solder resist covering copper foil traces formed on a substrate and the substrate, for insulation. The solder resist is formed such that exposed portions of the substrate between adjacent ones of the conductive traces each have a shape protruding in a direction of where the other printed circuit board is connected, with respect to exposed portions of the adjacent ones of the conductive traces, in a boundary between the connection part and a portion on which an insulating layer is formed.
