摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a terminal which allows for butt welding with high laser welding efficiency without reducing the strength significantly.;SOLUTION: A method of manufacturing a terminal 1 having a tube body calking portion 30 being crimped to a wire includes a step for preparing a base material composed of copper or a copper alloy of a terminal material including a tube development part for forming the tube body calking portion 30, a step for forming a nickel layer containing 10-50% volume fraction of high melting point inorganic conductive particles having a grain size of 0.3-10 μm on the tube development part, a step for forming a tin layer, as the outermost layer, on the nickel layer, a step for shaping into a tube body by bending and butting the tube development part, and a step for forming the tube body calking portion 30 by joining the butting part by laser welding. The steps are carried out in this order.;COPYRIGHT: (C)2014,JPO&INPIT
