ABSTRACT:
A daughter card assembly which provides relatively high conductive heat transfer from the electronic components on the daughter board to either an air or liquid cooled cold plate of a computer circuit module. The daughter card assembly has a daughter board with a plurality of electronic elements carried on an element side of the board. The opposite side of the board is a cooling side. The daughter board has one or more sockets which are electrically connected to the electronic elements on the board. The socket is adapted to plug into a connector carried on a mother board of a circuit module. A thermally conductive plate is disposed adjacent to and in thermal conductive contact with the cooling side of the daughter board. The conductive plate has an inner side facing the circuit module and an outer side on the opposite side. The plate is adapted to be in thermal conductive contact with the module cold plate to dissipate heat generated by the memory elements. Preferably, the conductive plate is sandwiched between the cooling sides of a pair of daughter boards with one board abutting against the inner side and the other board abutting against the outer side of the plate.
