  • Publication number: 20210272927
    Abstract: The present invention includes: an ultrasonic horn (14) to which two ultrasonic vibrations can be input to excite a capillary (15) mounted to a front end with different frequencies in a Y-direction and an X-direction; and a control unit (50) which adjusts the respective magnitude of the two ultrasonic vibrations. The Y-direction is a direction in which the ultrasonic horn (14) extends. The control unit (50) adjusts the respective magnitude of the two ultrasonic vibrations to adjust a ratio (?Y/?X) of amplitude of the capillary (15) in the Y-direction and the X-direction. Thus, degradation in the quality of the joining between wires and leads is suppressed.
