    Abstract: Methods of manufacturing printed wiring boards including electrically conductive constraining cores that involve a single lamination cycle are disclosed. One example of the method of the invention includes drilling a clearance pattern in an electrically conductive constraining core, arranging the electrically conductive constraining core in a stack up that includes B-stage (semi-cured) layers of dielectric material on either side of the constraining core and additional layers of material arranged to form the at least one functional layer, performing a lamination cycle on the stack up that causes the resin in the B-stage (semi-cured) layers of dielectric to reflow and fill the clearance pattern in the electrically conductive constraining core before curing and drilling plated through holes.

    Abstract: Integrated circuits and processes for manufacturing integrated circuits are described that use printed wiring board substrates having a core layer that is part of the circuit of the printed wiring board. In a number of embodiments, the core layer is constructed from a carbon composite. In several embodiments, techniques are described for increasing the integrity of core layers in designs calling for high density clearance hole drilling. One embodiment of the invention includes a core layer that includes electrically conductive material and at least one build-up wiring portion formed on an outer surface of the core layer. In addition, the build-up portion comprises at least one micro wiring layer including a circuit that is electrically connected to the electrically conductive material in the core layer via a plated through hole.

    Abstract: Mono-polar and bipolar fuel cell plates 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 percentage by weight of the conductive powder(s), conductive fiber(s), or a combination thereof is between about 20 % and 50 % of the weight of the conductive loaded resin-based material. 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, aluminum fiber, or the like.

    Abstract: A process and a device are useful for connecting contacts of a first electronic component to contacts of a second electronic component. The components are aligned in accordance with the order of connection and bonded to each other by a hot-melt adhesive charged with electrically conductive particles which are not connected to each other in an electrically conductive manner. During the bonding process, the connection regions of the components are moved toward each other in such a way that only directly opposite contacts are connected to each other electrically by the conducting particles in the adhesive. The device for implementing the process comprises a clamping device for fixing the components in the predetermined order of connection and a strip heater which heats the connection regions in order to melt the adhesive. The process and device make it possible to produce rapid and reliable contact between contacts located a short distance apart.
