Abstract
A housing for installation in motor vehicles to accommodate SMD electronic components disposed on one side of a multi-layer circuit board or film. A metal plate serves as the carrier for the circuit board or film, with the planar expanse of the metal plate being the same as or greater than that of the board or film, with the board or film being disposed on, attached to and electrically insulated from the metal plate. When the area of the metal plate is greater than that of the board or film, power components are disposed on the surface of the metal plate in a region not covered by the board or film, whereas when the area of the metal plate is substantially the same as that of the board or film, power components are disposed on the board or film, with the metal plate serving as a heat sink for the power components. A connector is mounted on the metal plate in a region covered by the board or film such that the connection pins of the connector are brought into the board or film, with the coupling side of the connector being on the planar side of the metal plate which is opposite the side carrying the board or film. Finally, a mechanical cover arrangement is attached to the metal plate to form a flat housing, with the mechanical cover arrangement covering the surface side of the metal plate carrying the board or film.
