Abstract:
Heat sinks, heat pipes, and other thermal management devices are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The ratio of the weight of the conducive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers to the weight of the base resin host is between about 0.20 and 0.40. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or the like, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or the like, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, or the like. The conductive loaded resin-based heat sink, heat pipe, or other thermal management devices can be formed using methods such as injection molding compression molding or extrusion. The conductive loaded resin-based material used to form the heat sinks can also be in the form of a thin flexible woven fabric that can readily be cut to the desired shape.
Abstract:
A printed wiring board structure having at least one chip-carrying layer adjacent a core fabricated of a metal matrix having disposed therein continuous pitch based graphite fibers. The chip carrying layers and the core have an interface therebetween and are integrally connected to each other through vias plated with an electrically and thermally conductive material to thereby provide a plurality of connection sites along this interface. The matrix is preferably fabricated of aluminum. Preferred fibers are fabricated of pitch based graphite. A substantial weight savings over a common molybdenum core printed wiring board is realized due to the significant reduction in density of the core material. A typically preferred present printed wiring board structure has several circuit layers and two chip-carrying layers each on opposite sides of the core, with each of the layers and the core having respective interfaces therebetween wherein each layer is integrally connected to the core at a plurality of connection sites, as required by circuit design, along the respective interfaces. Because of the plurality of connection sites along respective interfaces, superior thermal conductivity occurs from the layers to the core since heat travels through these connection sites to effectuate extremely efficient heat transfer and ultimate heat dissipation from the entire printed wiring board structure.

Abstract:
An electrical interconnect (10) is comprised of a woven mesh in which an array of parallel wires (20) is retained in spaced relation by a transverse array of nonconducting strands (30), the mesh being enclosed or encased within a resilient matrix. The conductive wires are on a close pitch to yield greater current carrying capacity and achieve a lower more stable resistance. With this construction a great number of wires are in contact with each contact pad to yield greater current carrying capacity and corresponding lower resistance. The closer pitch wires also provide greater redundancy of contact points. This structure can be custom configured in as many layers or in a variety of shapes as is desirable to achieve a given electrical performance. The woven mesh can be wrapped around a shaped substrate to provide electrical connections in a desired shape. The woven mesh interconnect can be integrated as part of a boot, wherein the boot receives an electrical device therein and the woven mesh interconnect provides electrical connection from the device within the boot to outside the boot. The woven mesh interconnect can be layered and shaped to form an interconnect which not only provides electrical interconnection but also provides a biasing force due to the shape of the device.
Abstract:
Electronic assemblies are fabricated by stacking alternate connecting layers and component layers. The component layers may be virtually any rigid structure having contact regions formed on at least one face thereof. The connecting layers are formed from anisotropic elastomeric conductors which in turn are fabricated by stacking a plurality of conductive sheets and insulating sheets, where the conductive sheets have a plurality of parallel electrically conductive elements formed therein. By introducing a curable elastomeric resin into the stacked structure so formed, and then curing the elastomer, a solid elastomeric block having a plurality of parallel electrically conductive elements running its length is obtained. Individual elastomeric conductors suitable as connecting layers interfacing between adjacent component layers are obtained by slicing the block in a direction perpendicular to the conductors.
