    Abstract: In a single-sided paper phenolic resin copper-clad laminate composed of a phenolic resin impregnated paper base having copper foils laminated on and resists applied on the face side thereof, resists formed of the same material as the resists on the face side are applied also on the reverse side of the phenolic resin impregnated paper base, so that the face side and the reverse side match approximately with each other in thermal expansibility. The single-sided paper phenolic resin copper-clad laminate warps only slightly even when the peak temperature is raised to a degree suitable for lead-free solder in the reflow process for mounting electronic components.

    Abstract: Biobased cross-linked compositions, methods of fabrication and structures, in particular biobased printed wiring boards using the compositions and methods of making the structures are described. Biobased materials such as lignin, crop oils, wood resins, tannins, and polysaccharides and combinations thereof are cross-linked, preferably using heat, a cross-linking agent, and an initiator. The materials fabricated have suitable properties for printed wiring boards which are made by impregnating a fiberglass or biobased cloth with an admixture of the biobased material, cross-linking agent and initiator which is processed by conventional methods to produce a printed wiring board.

    Abstract: A method and materials for drilling through-holes in printed circuit boards with a drilling tool is disclosed. The method involves the use of a lubricating entry material placed on the top surface of a stack of printed circuit boards and a lubricating backup board placed beneath the bottom surface of the stack of printed circuit boards. The lubricating entry material has a core with skins attached on both sides by a lubricant/adhesive. Similarly, the backup board has a core with skins attached on both sides by a lubricant/adhesive. The skins are hard enough to support the top and bottom surfaces of the printed circuit boards and thereby reduce burring at the entry point and exit point of the through-hole. The lubricant/adhesive coats the drilling tool during the drilling operation to reduce friction and thereby reduce the temperature of the drilling tool.

    Abstract: An electrically functional adhesive transfer for use in the manufacture and/or the design of flexible membrane circuits. Electrical circuit elements, instead of being printed directly upon polyester film substrates, are printed upon a carrier sheet. A pressure sensitive adhesive is applied over the exposed surfaces of the printed circuit pattern on the carrier sheet and covered by a release paper. The circuit later is applied to any desired substrate by peeling away the release paper and mounting the circuit by means of the pressure sensitive adhesive. The carrier sheet typically is peeled away after the circuit is adhesively bonded to the substrate. The carrier sheet desirably is transparent or translucent in order to facilitate visual alignment of the circuit pattern with the substrate to which it is being bonded.

    Abstract: An electric contact for connecting a conductive system present on an insulating substrate, in particular for automobile windshields, in which the conductive system is connected via a conductive path with an electric mating contact. A moisture-resistant electric contact which is easy to manufacture and can be universally used consists of a conductive path which is disposed directly on a support substrate as a path-shaped conductive layer on which an electric connecting line of the conductive system is located.
