RESIN COATED INSULATION BONDING WIRE

摘要

PURPOSE:To provide an insulation bonding wire which has good bonding property, is free from coating damage during bonding and has good insulation property even if wires come into mutual contact in a resin mold process. CONSTITUTION:A resin coating insulation bonding wire has a heat reduction amount of 85% or more at a temperature of 1100 deg.C in atmosphere and is coated with resin whose tensile strength at a temperature of 180 deg.C is 300kgf/cm<2> or more. As coating resin which satisfies characteristics, at least one kind of polyparabanic acid resin or polyarylate resin can be selected.
