Patent attributes
A printed circuit board assembly is formed by a press-fit connector attached to a printed circuit board. The press-fit connector includes a plurality of press-fit terminals and a housing. An overlapping resist part is formed on the printed circuit board. The overlapping resist part closely contacts the housing, and is arranged in a circular shape at an outer circumference of a through hole. By dipping the housing and the overlapping resist part closely contacting each other into a synthetic resin bath, the synthetic resin is filled in an inside of the through hole and a space surrounded by the overlapping resist part, and swarf of the press-fit terminal is fixed in the synthetic resin.
