Methods of calibrating an ultrasonic characteristic on a wire bonding system

A method of calibrating an ultrasonic characteristic on a wire bonding system to be calibrated, the method comprising the steps of:

• (a) determining a reference ultrasonic characteristic using reference response data from one or more reference wire bonding systems for formation of a wire bond;
• (b) determining a reference unacceptable ultrasonic characteristic using one or more reference wire bonding systems that results in an unacceptable wire bond condition;
• (c) determining a calibration unacceptable ultrasonic characteristic, on the wire bonding system to be calibrated, that results in an unacceptable wire bond condition;
• and
• (d) determining an ultrasonic characteristic setpoint for the wire bonding system to be calibrated using the reference unacceptable ultrasonic characteristic and the calibration unacceptable ultrasonic characteristic.
