Abstract

An apparatus and a method of mounting a power semiconductor (10) to an external heat sink (18) when both fastening faces (11, 13) of the semiconductor are inaccessible during the assembly process. The apparatus comprises a nut plate (20) that mates with the semiconductor (10) and a thermally conductive layer (28) that engages the nut plate (20) and wraps around the semiconductor (10) in a captive manner. The external heat sink (18) threadably engages the nut plate (20) without the need to access either fastening face (11, 13) of the semiconductor (10).
