METHOD FOR WELDING COIL TO INTEGRATED CIRCUIT OR TO MINI ELECTRONIC UNIT

摘要

PURPOSE: A method for welding coil to integrated circuit or to mini electronic unit is provided to protect a circuit or an electric unit from a machine stress or from a heat stress by preparing a preliminary process which removes an insulation coating from an electric wire. CONSTITUTION: A preliminary process removes an insulation coating partly from an electric wire(10) before a real welding process in a place which terminal parts(6,8) for welding to an electronic contact pad/bums(24,26) is located in. A heating press melts or sublimates the insulation coating in high temperature. A welding process is performed in much lower temperature than the preliminary process and permits a heat/machine stress against an integrated circuit(2) and the bumps(24,26) to decrease, while welding the terminal parts(6,8) to the bumps(24,26).
