Abstract: A warp-free laminate is produced by winding a first set of strands or filaments about a flat mandrel with a second set of strands being wound transverse to the first set. The two sets may be perpendicular to each other. The filaments are maintained under a controlled tension while being impregnated with a resin and during subsequent cure of the resin. In order to permit the formation of a warp-free product, the winding pattern is such that it forms a mirror image about a neutral axis or plane of symmetry. The winding pattern may be chosen to provide interstices in a predetermined pattern permitting punching out or high speed drilling of hole openings for subsequent printed circuit applications.

Abstract: A printed circuit board material composed of a reinforcing base material and a cured or uncured resin is disclosed, in which the base material is a fabric woven from hybrid yarns each of which is prepared from (I-1) at least one multifilament yarn made of glass fiber having a dielectric constant at 1 MHz of not higher than 5.5 or (I-2) at least one multifilament yarn made of heat resistant engineering plastic fiber having a dielectric constant at 1 MHz of not higher than 5.5 and (II) at least one yarn made of fluoroplastic long fiber and the thermosetting resin is a thermosetting resin whose dielectric constant after curing is not higher than 3.7. The material is excellent in dielectric properties and characteristics required for use in printed circuit board, such as heat resistance in soldering, flexural strength and peel strength of copper foil. The material shows substantial constancy of dielectric constant even with change of resin content and is therefore particularly suitable for use in a multilayer printed circuit board.

Abstract: Disclosed are improved laminates useful in the manufacture of multi-layer printed wiring boards (MLPWB) and laminates. Such improved composites contain at least one layer which is formed from a liquid crystal polymer selected from the group consisting of poly(para-phenylene benzobisthiazole), poly(paraphenylene benzobisoxazole), poly(2,5-benzothiazole), poly(2,5-benzoxazole), and mixtures thereof. The presently preferred liquid crystal polymer comprises poly(para-phenylene benzobisthiazole). The negative coefficient of thermal expansion and high modulus of elasticity of the liquid crystal polymers enable a laminate and MLPWB to be manufactured therefrom having a tailored coefficient of thermal expansion, broadly ranging from about 0 to 15 ppm/.degree. C. MLPWBs constructed of polymeric core layers also are possible utilizing the preferred liquid crystal polymers of the present invention.

Abstract: At both ends of glass cloth comprising warp yarns consisting of a number of glass monofilaments and weft yarns consisting of a number of glass monofilaments, the weft yarns being cut at the ends of the glass cloth, glass monofilament-fixing portions are formed by fusing the ends of the weft yarns, by substituting a synthetic resin yarn for the warp yarn at the end of the glass cloth and melting the synthetic resin yarn or by attaching an adhesive tape to the ends of the glass cloth. The glass cloth having the glass monofilament-fixing portions at both ends thereof is advantageous in that no broken pieces of glass monofilament were formed when preparing prepreg or laminate using the glass cloth, and the laminate has excellent accuracy of thickness.
