Patent ID: 7659615

Claim:
An assembly for cooling a power device comprising; a semiconductor die extending radially from an axis and having an upper surface and a lower surface, an upper substrate disposed axially above said upper surface of said die for providing a first heat dissipation path from said die through said upper substrate, a lower substrate disposed axially below said lower surface of said die for providing a second heat dissipation path from said die through said lower substrate, a circuit board spaced axially below said upper substrate to define a gap between said upper substrate and said circuit board and said circuit board defining a through hole having a periphery about said axis and including a plurality of circuit board conductors, a plurality of first interconnectors disposed in said gap and at the ends opposite one another of said upper substrate for creating electrical conduction between at least one of said circuit board conductors of said circuit board and said upper substrate, and said assembly including a plurality of second interconnectors disposed radially inward of said first interconnectors and between said upper substrate and said lower substrate for positioning said lower substrate in said through hole of said circuit board and for connecting said upper and lower substrates and allowing for the flow of current between said upper and lower substrates.
