Power module housing

A power module comprising:

• a housing having a plurality of apertures in a top surface of the housing and a pair of mounting flanges at opposite sides of the housing, each mounting flange including a flexible structure including at least one slot disposed between an opening in the mounting flange and the plurality of apertures;
• a plurality of press-fit pins that extend through the plurality of apertures and that are mechanically and electrically configured to be coupled to a plurality of vias, each aperture corresponding to a protrusion that extends above the top surface of the housing;
• and
• fasteners configured to couple the pair of mounting flanges to a heat sink, the flexible structure of each mounting flange reducing stress on the housing caused by the coupling.
