DISCRIMINATING DEVICE FOR PROPERIETY OF ULTRASONIC WIRE BONDER

摘要

PURPOSE:To discriminate the propriety of bonded states of metallic wires to bonding sections by means of a wire bonder using an ultrasonic wiring bonding method during the course of wire bonding. CONSTITUTION:In this ultrasonic wire bonder in which an ultrasonic vibrator element 6 for resonantly vibrating a capillary tool 1 is attached to a horn 3 constituted so that the horn 3 can press the capillary tool 1 which is fitted to the front end of the horn 3 and through which a metallic wire 2 is passed against a bonding section, the element 6 is connected to an ultrasonic wave detection circuit 11 through an amplifier 10.
