Patent ID: 8159828

Claim:
A low profile power module comprising: a front surface cover board being electrically conductive; a multi-layer printed circuit laminate, further comprising a plurality of bonded printed circuit layers each having a circuit thereon, that is physically and electrically bonded to said front surface cover board; an external ball grid array located on a back surface of the multi-layer printed circuit laminate for electrical connection to an external system; said multi-layer printed circuit laminate further comprising, along its front surface: a) a recessed component-enclosing pocket having the circuit atop its floor; b) a plurality of circuit components, completely enclosed inside the recessed component-enclosing pocket having a back-side component bonding area that is conductively bonded to the circuit such that the low profile power module encases said plurality of circuit components; and c) wherein at least one of said plurality of circuit components further comprises a power MOSFET device with a drain-contact electrically bonded to said front surface cover board wherein said power MOSFET device has connections on a top and a bottom surface; d) wherein at least one of the plurality of circuit components are flip chips with an active device area and a first part of a component bonding area located on a back-side and a second part of a component bonding area located on a front-side as referenced to the orientation of the low profile power module; e) wherein said power MOSFET device further having the source-contact and a gate-contact located on the back-side and the drain-contact located on the front-side as referenced to the orientation of the low profile power module; and said multi-layer printed circuit laminate further comprising a plurality of plated through holes for electrically connecting a portion of the external ball grid array to the front surface cover board whereby the low profile power module achieves an increased mechanical robustness and EMI/RFI immunity; wherein said front surface cover board is further made heat conductive so as to facilitate heat dissipation from said at least one of the plurality of circuit components; and comprises a heat dissipating means externally and heat conductively attached to a front surface of said front surface cover board so as to facilitate heat dissipation from said at least one of the plurality of circuit components.
