The present invention provides a wire non-attachment inspection system (100) of a semiconductor device (10), wherein: the wire non-attachment inspection system (100) comprises an ultrasonic oscillator (40), an ultrasonic transducer (42), a camera (45), a display (48), and a control unit (50); and the control unit (50) calculates the difference in image between one frame of a captured video and a previous frame before the one frame, and displays, on the display, an image of a wire for which the difference exceeds a prescribed threshold value so as to be displayed differently than the image of another wire.

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 (ΔY/ΔX) 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.

An ultrasonic transducer system is provided. The ultrasonic transducer system includes: a transducer mounting structure; a transducer, including at least one mounting flange for coupling the transducer to the transducer mounting structure; and a tuned resonator having a desired resonant frequency, the tuned resonator being integrated with at least one of the transducer mounting structure and the at least one mounting flange.

A method of determining a shear strength of a bonded free air ball on a wire bonding machine is provided. The method includes the steps of: (a) providing a free air ball at a working end of a wire bonding tool; (b) bonding the free air ball to a bonding location of a workpiece; (c) moving the wire bonding tool, while in contact with the bonded free air ball, in a direction along the bonding location; (d) monitoring wire bonding process signals during step (c); and (e) determining a shear strength using the wire bonding process signals monitored in step (d).

To provide a wire bonding apparatus, which is insusceptible to a bonding state at a second bonding point due to a wire cut error or the like, or to members such as a capillary and a wire, and is capable of automatically protruding the wire from a leading end of the capillary, provided is a wire bonding apparatus including: a capillary (6) having a through hole through which a wire (40) is to be inserted; a holding unit, which is provided above the capillary (6), and is configured to hold the wire (40) inserted through the capillary (6); and a vibrating unit configured to vertically vibrate the capillary (6). Under a state in which the holding unit holds the wire (40), the vibrating unit vertically vibrates the capillary (6) so that the wire (40) is protruded from the leading end of the capillary.
