    Abstract: Power and ground planes that are used in Printed Circuit Boards (PCBs) and that comprise porous, conductive materials are disclosed. Using porous power and ground plane materials in PCBs allows liquids (e.g., water and/or other solvents) to pass through the power and ground planes, thus decreasing failures in PCBs (or PCBs used as laminate chip carriers) caused by cathodic/anodic filament growth and delamination of insulators. Porous conductive materials suitable for use in PCBs may be formed by using metal-coated organic cloths (such as polyester or liquid crystal polymers) or fabrics (such as those made from carbon/graphite or glass fibers), using metal wire mesh instead of metal sheets, using sintered metal, or making metal sheets porous by forming an array of holes in the metal sheets. Fabrics and mesh may be woven or random. If an array of holes is formed in a metal sheet, such an array may be formed with no additional processing steps than are performed using conventional PCB assembly methods.

    Abstract: An inexpensive and high throughput process for manufacturing a printed circuit board (PCB) substrate includes first weaving a plurality of electrically non-conductive strands (e.g., fiberglass yarns) and at least one electrically conductive strand (e.g., a copper wire) to form a woven fabric with an upper surface and a lower surface. Next, the woven fabric is impregnated with a resin material to form an impregnated fabric, which is then cured to form a cured fabric. The upper and lower surfaces of the cured fabric are subsequently planed. The planing step segments the electrically conductive strand(s) and forms a PCB substrate that includes a planarized cured fabric with upper and lower planed surfaces and a plurality of electrically conductive strand segments extending from the upper planed surface to the lower planed surface. Since each of the electrically conductive strand segments extends from the upper planed surface to the lower planed surface, the segments function as electrically conductive vias of the PCB substrate. Also, a PCB substrate that includes a planarized woven fabric with a cured resin material impregnated therein. The planarized woven fabric includes planed upper and lower surfaces and a plurality of integrally formed electrically conductive strand segments (e.g., copper wire segments) extending from the upper planed surface to the lower planed surface. Since the electrically conductive strand segments were formed integrally with the remainder of the planarized woven fabric, PCB substrates are of high mechanical stability.

    Abstract: A printed circuit board, containing thermal pads, is adhered to a rigidizer plate whereupon the entire unit can then be bent over itself to create a compact assembly which can be substantially smaller, but contain the same number of traces and electrical components, as an unbent printed circuit board of the same surface area. Further, a complete housing assembly is formed which is sealed on each edge of the rigidizer by inserting the edge into a panel with a groove. This assembly provides a secure fit that provides great stability with a relatively low weight and volume. The assembly also provides a better RF non-mechanical connection and much better thermal performance.

    Abstract: An electrical interconnect includes a woven mesh in which an array of parallel wires is retained in spaced relation by a transverse array of nonconducting strands, 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.

An organic matrix is preferably fabricated of a polymer material such as an epoxy resin. Preferred fibers are fabricated of pitch based graphite. 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.
