Abstract
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.
Claims4
A printed circuit board assembly comprising:
- a printed circuit board having conductive patterns formed on an insulating board, and a through hole connected to the conductive pattern;
- a press-fit connector having a press-fit terminal to be pressed into the through hole for being electrically connected to the conductive pattern, and a housing for receiving the press-fit terminal;
- an overlapping resist part formed on a press-fitting side of the printed circuit board where a resist for protecting the conductive patterns is overlapped with at least an outer edge of a circular conductive part surrounding the through hole;
- and
- synthetic resin for filling an inside of the through hole and a space surrounded by the overlapping resist part in a state that the press-fit connector is attached to the printed circuit board, and the housing and the overlapping resist part closely contact each other.
A method for producing a printed circuit board assembly, said printed circuit board assembly including:
- a printed circuit board;
- and
- a press-fit connector
- said printed circuit board having conductive patterns formed on an insulating board and a through hole electrically connected to the conductive patterns, a resist for protecting the conductive patterns and an overlapping resist part overlapping with at least an outer edge of a circular conductive part surrounding the through hole,
- said press-fit connector having a press-fit terminal to be pressed into the through hole for being electrically connected to the conductive pattern, and a housing for receiving the press-fit terminal,
- said method comprising the steps of:
- making the overlapping resist part closely contact the housing by attaching the press-fit connector on a side where the overlapping resist part of the printed circuit board is mounted;
- filling an inside of the through hole and a space surrounded by the overlapping resist part with liquid synthetic resin by dipping the printed circuit board and the press-fit connector attached to each other in a liquid synthetic resin bath in a direction from the printed circuit board to the press-fit connector;
- and
- curing the synthetic resin adhering to the printed circuit board and the press-fit connector attached to each other after pulling up the printed circuit board and the press-fit connector from the liquid synthetic resin bath.
