Abstract: A printed circuit board (PCB) composite material includes a polymer layer and a fiber layer encapsulated within the polymer layer. The fiber layer includes a first monolayer of continuous silica fibers longitudinally co-aligned in a first direction. Each continuous silica fiber in the first monolayer extends without discontinuity through the polymer layer such that opposed ends of each continuous silica fiber are adjacent to a perimeter of the polymer layer. The PCB composite material has a dielectric loss tangent of less than or equal to about 0.0015 at 15 GHz or higher frequency. A printed circuit board (PCB) includes the PCB composite material and at least one conductive layer disposed on a side of the PCB composite material.

Abstract: Woven glass cloth and method of its manufacture suitable for use as a resin-impregnated substrate for printed circuits in which the major dimension or transverse axis of the elliptical warp yarns exceeds a predetermined fraction of that dimension of the fill yarns of the woven cloth. Multi-filament warp yarns are typically subjected to tensile stress during weaving and firing such that the yarn compaction prevents the thorough impregnation by a resin. The result is that voids are maintained along the innermost filaments of the yarn. These voids, when filled with materials other than resin, such as plating solution, ultimately produce circuit failures.

Abstract: A nonwoven fabric constituted of high-flatness glass fibers whose cross sections have aspect ratios of 2.0 to 10 and rates of filling of 85 % or above, preferably 90 % or above. Such glass fibers have nearly rectangular cross sections and therefore can be arranged in an extremely dense state to give a nonwoven fabric which is extremely thin and has a high bulk density. The fabric can give laminates which are enhanced in the glass fiber content and improved in the surface smoothness, thus being suitably usable as the reinforcement for printed wiring boards. The glass fibers can be produced by the use of, e.g., a nozzle equipped with a tip which has a flat orifice and whose major-axis wall is partially cut out on one side.

Abstract: A nonwoven fabric is constructed of a highly flat glass fiber which is a glass fiber whose section is flat and has a flatness ratio of 2.0 to 10 and which has such a section that the packing fraction is at least 85%, preferably at least 90%. In this nonwoven fabric, the glass fiber section has a shape near rectangle, and hence, the glass fibers can be arranged very densely to form a thin nonwoven fabric having a high bulk density, and when it is used as a laminate material, the glass fiber content can be increased and the surface smoothness can simultaneously be enhanced and can be used appropriately as a reinforcing material for a printed wiring board. Moreover, the above flat glass fiber can be produced by use of, for example, a nozzle having such a shape that one side of the major axis walls of a nozzle chip having a flat nozzle hole is partly notched.
