摘要： A chip module having a chip with a flexible multilayer redistribution thin film attached thereto for connection to a substrate. The thin film acts as both a redistribution medium with multiple layers of redistribution metallurgy for chip power and signals and as a compliant medium to relieve stresses caused by thermal expansion mismatch between chip and substrate. Modules comprising chip and thin film may be fabricated at the chip or wafer level. The upper surface of the thin film has an array of pads matching the array of pads on the chip or wafer while the lower surface has pads matching those of the substrate. The multilayer thin film is first formed on a temporary substrate and then the chip is attached to the thin film before release from the temporary substrate. After release, the module is ready for mounting to the second level packaging substrate, such as a chip carrier or PCB. Where the multilayer thin film is formed directly on a wafer, the wafer is then diced to form the module.

摘要： An electronic package including as part thereof a thermally conductive arrangement for restricting thermal fluid material motion about a heat-generating device, thereby assuring effective heat transference from the heat-generating device (e.g., module) to a cooling member (e.g., spaced heat sink), this arrangement preferably including: (1) a thermal fluid (e.g., thermal grease); and (2) structural elements (e.g., wire mesh, heat sink ridges, etc.). For restricting fluid movement, sealing structures (e.g., external gaskets) may be used to further assure fluid containment to a specified location. Pressure generation means (e.g., a plunger) can be used to increase fluid pressure when pressure droppages occur.

摘要： A method of enhancing the passive thermal management of electronic packages, and an electronic package consisting of a vertically-oriented substrate, such as a printed circuit board or the like, a heat-generating electronic module, for example, containing at least one chip which is positioned on a substrate, and a cover plate located adjacent to the module at a predetermined spaced relationship therefrom. The cover plate includes at least one opening located adjacent the module at a predetermined location relative thereto so as to ensure a maximum cooling air flow impinging on the module, and which air flow thereafter passes upwardly between the substrate and the cover plate. The cover plate may be equipped with a heat-sink structure, such as fins, for cooling the module, which structure is adapted to project through the opening formed in the cover plate or to lie flush therewith.

摘要： A demountable, and thus re-usable, conductive heat sink for dissipation of excess heat of an electronic component. The heat sink uses a T-bolt and T-slot for attachment to the electronic component and the printed circuit board, respectively. This attachment eliminates the typical concerns associated with the placement of traces on the PCB to accommodate the holes placed therein for the attachment of conventional heat sinks. The improved designed also facilitates demounting of the heat sink from the printed circuit board and the electronic component without damage thereto.

摘要： A heat dissipating flexible or resilient standoff is mechanically clamped between an electronic module and substrate, such as, PCB. The clamping arrangement comprises a heat sink compressing a thermally conductive flexible interface pad over the upper surface of the electronic module by way of mechanical linkage to the PCB. The heat dissipating flexible standoff provides a force opposing the compression force to thereby reduce stress on solder ball connections between electronic module and PCB. Thermally conductive flexible standoffs in the form of spring arrangements, such as a wire mesh, act to provide heat dissipation by both thermal conduction and thermal convection. A thermally conductive flexible polymer pad and a layer of porous metal foam may also act as thermally conductive standoffs.
