Claims16
A metal-clad laminate produced by impregnating composite fabric comprising 30-95% by weight of aromatic polyamide fiber and 5-70% by weight of glass fiber arranged together, with a resin to form a prepreg, laminating a plurality of said prepregs together with at least one metallic foil, and molding the laminated metal-clad prepregs under heat and pressure.
A copper-clad laminate comprising a plurality of composite fabric-reinforced resin prepregs laminated together with and interposed between copper foils, said composite fabric being a woven cloth formed of combination yarns containing 30-95% by weight of aromatic polyamide yarn twisted together with 5-70% by weight of glass yarn.
A copper-clad laminate produced by impregnating a composite fabric comprising 30-95% by weight of aromatic polyamide fiber and 5-70% by weight of glass fiber with a resin to form a prepreg, laminating a plurality of the resulting prepregs together, and molding the laminated prepregs under heat and pressure;
- said composite fabric being a composite cloth obtained by weaving a combination yarn obtained by twisting one or more yarns of aromatic polyamide fiber together with one or more yarns of glass fiber and the resulting laminate being overlaid and bonded with one or more copper foils and being suitable for mounting chips thereon.
