Abstract:
Lighting 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 conductive 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 lighting devices can be formed using methods such as injection molding compression molding or extrusion. The conductive loaded resin-based material used to form the lighting devices can also be in the form of a thin flexible woven fabric that can readily be cut to the desired shape.

A printed wiring board structure (30) having at least one chip-carrying layer (16) adjacent a core (32) fabricated of a metal matrix (34) having disposed therein continuous pitch based graphite fibers (36). The chip carrying layers (16) and the core (32) have an interface (52) therebetween and are integrally connected to each other through vias (48) plated with an electrically and thermally conductive material (50) to thereby provide a plurality of connection sites along this interface (52). The matrix (34) is preferably fabricated of aluminum. Preferred fibers (36) are fabricated of pitch based graphite. A typically preferred present printed wiring board structure (30) has several circuit layers and two chip-carrying layers (16) each on opposite sides of the core (32), with each of the layers (16) and the core (32) having respective interfaces (52) therebetween wherein each layer is integrally connected to the core (32) 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 (52), superior thermal conductivity occurs from the layers (16) to the core (36) since heat travels through these connection sites to effectuate extremely efficient heat transfer and ultimate heat dissipation from the entire printed wiring board structure (30).

Abstract:
A method of forming an anisotropic electrical connection between conductive elements (22, 24) having an oxide layer (28) is disclosed. The method comprises the use of an adhesive (30) including carbon fibres (32) and metallic particles (34). On the application of pressure, the carbon fibres (32) penetrate the oxide layer (28), whilst the metallic particles (34) deform such that a good electrical connection is made between overlying elements (22, 24).
Abstract:
An interlevel connector, a multilayer wiring board assembly, and method for making the same are presented. The interlevel connector includes a dielectric substrate having a plurality of through holes and a corresponding plurality of pultrusions. Each pultrusion includes a plurality of electrically conductive fibers and an electrically conductive or insulating host material carrying the plurality of fibers, each of the plurality of pultrusions being located in a respective through hole and having fibrillated portions extending from surfaces of the dielectric substrate. The interlevel connector is used in the construction of a multilayer wiring assembly in which first and second wiring boards having respective conductive portions are interconnected. The interlevel connector is located adjacent and between the first and second wiring boards, whereby the fibrillated portions of the pultrusion extending from the surfaces of the dielectric substrate contact the conductive portions of the first and second wiring boards. The wiring boards can be permanently or removably locatable adjacent the dielectric substrate.
