METHODS OF DETECTING CONNECTION ISSUES BETWEEN A WIRE BONDING TOOL AND AN ULTRASONIC TRANSDUCER OF A WIRE BONDING MACHINE

Abstract:

A method of detecting potential issues in connection with engagement between a wire bonding tool and an ultrasonic transducer of a wire bonding machine is provided. The method includes the steps of: (a) providing electrical power to an ultrasonic transducer at each of a plurality of levels of electrical power; (b) detecting an electrical characteristic of the ultrasonic transducer at each of the plurality of levels of electrical power; and (c) determining if the electrical characteristic of the ultrasonic transducer at each of the plurality of levels of electrical power is acceptable.
