Abstract

PURPOSE:To compose the titled apparatus of high reliability without using the mechanical contact by utilizing damping of output current from the ultrasonic oscillator to the vibrator in time of contact of the capillary tip to the bonding face. CONSTITUTION:The vibrator 1 is vibrated by the ultrasonic output potential from the ultrasonic oscillator 4 via the transformer 5 and related in the arrow direction around the sustaining shaft 3 by the driving device (not illustrated) and the metal fine wire 12 is bonded to the bonding face 12a of a pellet 11 by pushing with the capillary tip 2. The value of applied current to the vibrator 1 is detected as the potential value by the detector 22 on said apparatus, this value is compared to the standard potential value. When the difference exceeds the set value, the driving device is controlled by the controller 23 and the descent of the capillary tip 2 is stopped and the bonding operation is made to do.
