Method of vertically vibrating a bonding arm
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.
Device and method for positioning first object in relation to second object
This mounting device (100) comprises: a base (10) that moves linearly in relation to a substrate (16); a bonding head (20) that is attached to the base (10); a camera (25) that is attached to the base (10) and identifies the position of the substrate (16); a linear scale (33) having a plurality of graduations along the movement direction; a bonding head-side encoder head (31); and a camera-side encoder head (32). A control unit (50) causes the base (10) to move to a position where the bonding head-side encoder head (31) detects the position of a graduation. Due to this configuration, positioning accuracy of a semiconductor die (15) in relation to the substrate (16) is improved.
WIRE BONDING APPARATUS
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.
Wire clamp apparatus calibration method and wire bonding apparatus
This wire clamp apparatus calibration method comprises: a step for driving a driving piezoelectric element by applying a predetermined frequency that causes a pair of arm portions to vibrate in an opening/closing direction; a step for detecting whether or not end portions of the pair of arm portions collide with each other on the basis of an output current outputted from the driving piezoelectric element when the pair of arm portions are vibrating in the opening/closing direction; a step for calculating, on the basis of the detection result, reference voltages in a state where the pair of arm portions are closed; and a step for performing calibration of a drive voltage to be applied to the driving piezoelectric element on the basis of the reference voltages. Accordingly, accuracy improvement and stabilization in an opening/closing operation of the wire clamp apparatus can be achieved.
