Abstract:
1. A semiconductor module arrangement, comprising: a semiconductor module having a top side, an underside opposite the top side, and a plurality of electrical connection contacts formed at the top side; a printed circuit board; a heat sink having a mounting side; and one or more fixing elements for fixing the printed circuit board to the heat sink; wherein either a multiplicity of projections are formed at the underside of the semiconductor module and a multiplicity of receiving regions for receiving the projections are formed at the mounting side of the heat sink; or a multiplicity of projections are formed at the mounting side and a multiplicity of receiving regions for receiving the projections are formed at the underside, each of the projections extend into one of the receiving regions; wherein the semiconductor module is electrically conductively connected to and mechanically held by the printed circuit board at the connection contacts; wherein the printed circuit board is connected to the heat sink by the one or more fixing elements so that the semiconductor module is interposed between the heat sink and the printed circuit board; and wherein no direct positively locking connection is provided between the semiconductor module and the heat sink.
