摘要:
A localized cooling apparatus is provided for individually cooling integrated circuit chips mounted on a circuit board for insertion into a computer backplane. The cooling apparatus consists of a circuit board occupying a first slot and having an integrated circuit chip mounted thereon, the performance of which is known to improve by cooling, a heat removal assembly consisting of a heat sink attached to a card edge portion and occupying an adjacent second slot, and a thermoelectric cooler intimately bonded to both the chip and heat removal assembly. A controller provides power via the connector of the second slot to the thermoelectric cooler and stabilizes the temperature of the chip to a predetermined value.

The present invention is directed to a structure for positioning electronic modules of an electronic system therein, and particularly to a rack often called a card cage in which circuit boards are disposed. The rack embodying the invention incorporates a frame having four sides and a back plate. Two of the opposite sides are grilles. The frame is adapted for supporting printed circuit boards perpendicular to the grill. Thus, a fluid cooling medium, such as air, can enter the rack through one of the grilles, flow along and between the circuit boards and exit through the other grilles. The resistance to the flow of such air for cooling by the grilles is significantly greater than the boards disposed therein. Thus, the grilles permit a uniform coolant flow for each of the circuit boards in the rack.The rack has a lever assembly which remotely actuates connectors positioned in the rack to contact the circuit boards positioned therein. The lever assembly is further provided with a spring member which serves as a force-limiting device such that excessive force is not applied to the boards and to the connectors when the boards are inserted into the rack. The rack also has guiding members for guiding warped circuit boards into position within the rack.

A system, method, and apparatus are included for providing additional space between an integrated circuit package and a circuit board. An integrated circuit package is provided including a plurality of integrated circuit package contacts. Also provided is a circuit board in electrical communication with the integrated circuit package. Further, the integrated circuit package, the integrated circuit contacts, and/or the circuit board is configured for providing additional space between the integrated circuit package and the circuit board to position at least a portion of at least one component between the integrated circuit package and the circuit board.

An IC chip assembly includes a chip having an array of exposed contacts at a first face thereof, a substrate having an array of exposed contacts at a face thereof and a compliant interposer with exposed contacts at opposite faces thereof positioned between the chip and substrate so that contacts on the opposite faces of the interposer engage the contacts on said chip and substrate, respectively. A thermal transfer member contacts the opposite face of the chip and is engaged to the substrate so as to compress the interposer thereby simultaneously establishing relatively low inductance electrical connections between the chip contacts and the substrate contacts and good thermal contact between the chip and the thermal transfer member. The assembly is particularly adapted to provide power to the chip of a TAB-type integrated circuit assembly which includes a flexible lead frame connected between the chip and the substrate.

One embodiment of the present invention sets forth a heat spreader module for dissipating thermal heat generated by electronic components. The assembly comprises a printed circuit board (PCB), electronic components disposed on the PCB, a thermal interface material (TIM) thermally coupled to the electronic components, and a heat spreader plate thermally coupled to the TIM. The heat spreader plate includes an embossed pattern. Consequently, surface area available for heat conduction between the heat spreader plate and surrounding medium may be increased relative to the prior art designs.

A processor-inclusive memory module (PIMM) is disclosed. In one embodiment of the present invention, the PIMM includes a printed circuit board having first and second opposing surfaces. The printed circuit board also has an address line formed therein. A first SRAM is mounted on the first surface of the printed circuit board. The present PIMM is further comprised of a second SRAM mounted on the second surface of the printed circuit board. The second SRAM is mounted on the second surface of the printed circuit board directly opposite the first SRAM mounted on the first surface of the printed circuit board. The first and second SRAMs are coupled to the address line by respective cache buses. A processor is also mounted on the first surface of the printed circuit board, and is coupled to the address line. In one embodiment of the invention, a heat sink is thermally coupled to the processor. The processor has a plurality of contact pads disposed thereon. Electrical connectors extend from the second surface of the printed circuit board. The electrical connectors are electrically coupled to respective contact pads of the processor. In the present PIMM, the electrical connectors are adapted to be removably attached to a mother board. In so doing, the present PIMM is removably attachable to a mother board.
