Abstract:
1. A bolster plate assembly for a semiconductor module assembly, comprising: a bolster plate including a plurality of openings; a leaf spring including a plurality of stand offs that project out from the leaf spring, the leaf spring being pre-loaded onto the bolster plate, where the leaf spring releasably attached to the bolster plate by positioning the plurality of stand offs within corresponding openings in the bolster plate, and the leaf spring being positioned to provide a force in a direction generally away from the bolster plate; a first distance between two of the openings being greater than a second distance between two of the stand offs when the leaf spring is in an uncompressed state; and the leaf springs being configured to release from the bolster plate upon attaching a semiconductor module assembly to the bolster plate that causes the leaf spring to exert the force in the direction generally away from the bolster plate and against the semiconductor module assembly.
