Abstract: A semiconductor module includes a base plate having an inner region adjacent an edge region, a substrate attached to the inner region of the base plate and a heat sink on which the base plate is mounted so that the base plate is interposed between the substrate and the heat sink and at least part of the inner region of the base plate contacts the heat sink. The module further includes a stress relief mechanism configured to permit the base plate to bend away from the heat sink in the edge region responsive to a thermal load so that at least part of the inner region of the base plate remains in contact with the heat sink.

The first fitting segment and the first adjustment segment are connected to the first housing in a captive manner even when the undercut connection is not formed.

Abstract: A power semiconductor module includes an electrically conductive connecting element, an accommodating region, and a clamping element which can be brought from a first position into a second position. If the clamping element is situated in the first position, a connecting region of a module-external connecting conductor can be inserted into the accommodating region and be clamped to the power semiconductor module with the formation of an electrically conductive connection between the connection region and the connecting element. For this purpose, the clamping element is brought from the first position into the second position.

Abstract: A die fixing method is disclosed which includes providing a substrate having a metallized surface, forming a joining material on the metallized surface and placing a die alignment member with a plurality of openings on the substrate so that portions of the joining material are exposed through the openings. The method further includes placing a plurality of dies in the openings of the die alignment member with a bottom side of each die in contact with part of the joining material and attaching the plurality of dies to the metallized surface of the substrate at an elevated temperature and pressure, the die alignment member withstanding the elevated temperature and pressure. The die alignment member is removed from the substrate after the plurality of dies are attached to the metallized surface of the substrate.

Abstract: A power semiconductor module includes a package having a first package portion and a second package portion. The side of the first package portion facing the second package portion has an anchoring element with a first recess. The second package portion includes a second recess with an indentation which receives the anchoring element. To produce a mechanically firm connection between the first package portion and the second package portion, a plug-in element is inserted in the first recess and the second recess. The plug-in element displaces the anchoring element transversely with respect to the plug-in direction, causing the anchoring element to engage the indentation so that a form-fit connection is produced between the first package portion and the second package portion. The plug-in element prevents the anchoring element from disengaging the indentation.
