REINFORCING FIBER WOVEN FABRIC USED FOR LAMINATE TO BE PROCESSED BY LASER BEAM

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing fiber woven fabric giving a laminate which is processed by laser beams, scarcely generates the irregularity in the diameters of holes formed by the laser beams and does not cause the detects of insulation and conduction, when used as a substrate of printed circuit. SOLUTION: This reinforcing fiber woven fabric used for a laminate to be processed by laser beams comprises a plain woven fabric in which at least one kind of reinforcing fibers constituting warps and wefts comprise glass fibers and which has a reinforced fiber woven fabric thickness of <=80μm and a glass porosity of <=10%.
