Abstract
A power module assembly () with low thermal resistance and enhanced heat dissipation to a cooling medium. The assembly includes a heat sink or spreader plate () with passageways or openings () for coolant that extend through the plate from a lower surface () to an upper surface (). A circuit substrate () is provided and positioned on the spreader plate () to cover the coolant passageways. The circuit substrate () includes a bonding layer () configured to extend about the periphery of each of the coolant passageways and is made up of a substantially nonporous material. The bonding layer () may be solder material which bonds to the upper surface () of the plate to provide a continuous seal around the upper edge of each opening () in the plate. The assembly includes power modules () mounted on the circuit substrate () on a surface opposite the bonding layer (). The power modules () are positioned over or proximal to the coolant passageways.
