An apparatus comprising a heat dispersion device having a first end. The first end has a shape different than that of the remainder of the heat dispersion device. The apparatus also comprises a jacket coupled to the heat dispersion device at the first end. The jacket has another shape associated with that of the remainder of the heat dispersion device.

A processor module includes a processor and a voltage regulator both mounted on a carrier. The voltage regulator is mounted with its contacts under compression to ensure good electrical contact with pads on the carrier. Heat sinks mounted respectively on the processor and the voltage regulator are rigidly coupled to each other to provide rigidity to the module and thus maintain the desired compression of the voltage regulator contacts.

A method of sizing a load plate for an Application Specific Integrated Circuit (ASIC) assembly includes compressing the load plate prior to installation in the ASIC assembly. The compression is adjusted to cause the load plate to provide a target load when installed in the ASIC assembly.

A connection assembly permits a make first and break last connection for primary power. The assembly includes a first pair of connectors, a second pair of connectors, and a compliance element associated with one of the first pair of connectors. The compliance element enables the first pair of connectors to mate prior to the mating of the second pair of connectors and to enable the first pair of connectors to disengage after the disengagement of the second pair of connectors.

Disclosed is land grid array (LGA) assembly using a compressive load. An LGA assembly includes a first component located on the top of the LGA assembly; a center load screw coupled to the first component; and a second component, wherein the center load screw is received on the second component upon turning the center load screw in a first direction. Further turning of the center load screw in the first direction after the center load screw is received on the second component, operates the first component to apply a compressive load within the LGA assembly.

An integrated circuit attachment implementation includes a mechanism for inserting and securely holding a replaceable component to an integrated circuit. The mechanism includes a top plate, leaf springs in contact with the top plate, a leaf spring cradle that carries the leaf springs, with the cradle including upper projections that project through corresponding slots in the top plate, a pin inserted through openings in the upper projections, and a linear slide cam located on an upper surface of the top plate between the upper projections and further located below the pin. The cam operates in a first position to transfer a load the replaceable component to securely hold the replaceable component to the integrated circuit and a second position to allow placement of the replaceable component on the integrated circuit.

A method and substrate using a wave spring to clamp a component to the substrate. One embodiment of the invention involves a method to use a wave spring to clamp a component to a substrate. The method includes placing the component on the substrate, placing a structure having holes on the component, placing a number of wave springs on a corresponding number of bolts, inserting the bolts into the holes in the structure, and attaching the bolts to the substrate. A second embodiment of the invention involves a substrate with an electrical contact area, an interposer placed on the electrical contact area, a component placed on the interposer, a block having holes placed on the component, bolts and wave springs inserted in the holes, wherein the bolts and wave springs clamp the component, the interposer and the substrate together on the electrical contact area of the substrate.

The invention is a heat sink assembly for the removal of heat from semiconductor and power converter modules. The packaging design for semiconductor modules and power converter modules provides efficient heat removal and a tight Faraday Cage. There is a heat transfer layer sandwiched between a CPU module and a power converter module. The heat sink assembly includes a heat transfer layer, a fin stack, and a series of heat pipes. The heat transfer layer has a slot for passage of power cables and sense lines which connects both the CPU module and the power converter module, and the power converter module and the printed circuit board. The heat sink chamber also serves as a Faraday Cage and thus attenuates EMI from the semiconductor module, the power converter module, the power cables, and the sense lines.
