摘要:
An apparatus adapted for use in a field replacement unit that is to be coupled to an electronic module. Included in the apparatus are a cover assembly; a biasing assembly disposed within the cover assembly; and, an aligning and coupling mechanism retained in the cover assembly in juxtaposed relation with the biasing assembly for mounting an interposer assembly in a manner, whereby the interposer assembly is generally self-aligned along in-plane axes with respect to the cover assembly for subsequent coupling to an electronic module. A method for use of the apparatus is disclosed.

A heat transfer apparatus comprises a load frame having load springs and an open region that exposes an electronic component. The load frame is mounted to a printed circuit board on which the electronic component is mounted. A heat sink assembly is disposed on the load frame and has a main body in thermal contact with the electronic component through a thermally conductive material. The heat sink assembly has load arms for engaging the load springs. A load plate extends between the load arms and has an actuation element operative to displace the main body relative to the load plate and thereby resiliently deform the load springs and produce a load force that compresses the thermally conductive material to achieve a desired thermal interface gap between the main body and the electronic component. Non-influencing fasteners secure the heat sink to the load frame and maintain the desired thermal interface gap.

A heat transfer apparatus comprises a thermally conductive member including a base having one or more surfaces adapted to absorb heat from an electronic component, and a mounting assembly including at least one mounting member directly coupled to the base and for direct attachment to the electronic component so that loading forces for mounting on it the electronic component are not directly applied to the base. The thermally conductive member is a graphite-based material. A compliant force applying mechanism is mounted generally on the base for controlling forces applied on the base.

A multichip module subassembly is disclosed which provides for a heatsink, a thermal interface, a module cap upon which a multichip module is mounted, a land grid array interposer, and an assembly cover. The module cap has shimmed load posts and adjustable brackets for precise alignment and loading of the interposer onto the module. The cover may have a springplate for precise preloading of the interposer onto the multichip module for transportation. The multichip module subassembly is easily used as a field replaceable unit.

An apparatus and method are disclosed to provide heat pipe cooling for semiconductor chips mounted on a module. Each chip is provided its own heat pipe for cooling. A piston on the end of each heat pipe is loaded against each chip with a predetermined force without the need for counting turns of a screw or use of torque measurement tools. Each heat pipe draws heat away from the chip it is loaded against, carrying the heat to a heat sink for dissipation into the ambient. A large multichip module can be loaded against a land grid array interposer with uniform loading of the interposer. This interposer loading is accomplished independently of the loading of the heat pipes against the chips.
