Patent ID: 8680666

Claim:
A power module assembly comprising: a plurality of packages, each of said plurality of packages comprising: a thin generally rectangular body having top and bottom wafer assemblies each having an insulation layer formed between two conductive layers, wherein said top wafer assembly includes a top metallic surface and said bottom assembly includes a bottom metallic surface; and first and second end surfaces perpendicular to and joining said top and bottom metallic surfaces; at least one central semiconductor die disposed on an inner surface of said bottom wafer assembly of a respective one of said plurality of packages and having a plurality of terminals extending from at least said first end surface of said respective one of said plurality of packages; said inner surface having a plurality of dimples formed thereon, said plurality of dimples extending through said inner surface and configured to act as solder stops and to self-align said at least one central semiconductor die; said at least one central semiconductor die having first and second opposite surfaces thermally connected to said top and bottom metallic surfaces of said respective one of said plurality of packages and electrically insulated therefrom, and an insulation housing overmolded around side edges of said top and bottom metallic surfaces, enclosing at least a portion of the periphery of said respective one of said plurality of packages and insulating said plurality of terminals from said top and bottom metallic surfaces; said power module further comprising a thermally conductive clip supporting said plurality of packages in a spaced parallel relationship, said top and bottom metallic surfaces of adjacent ones of said plurality of packages being spaced by a given space, being coextensive with respect to one another and being exposed for heat transfer to a cooling medium.
