Abstract

A wire bonding apparatus according to an embodiment bonds a wire to a bonding portion by generating an ultrasonic vibration in a state of pressing the wire onto the bonding portion. The wire bonding apparatus includes a bonding tool that causes the wire to contact the bonding portion and applies a load, an ultrasonic horn that generates the ultrasonic vibration, a load sensor that continuously detects the load applied from the bonding tool to the bonding portion, and a controller that controls the operation of the bonding tool and the ultrasonic horn. The controller analyzes data of the load output from the load sensor between when the wire contacts the bonding portion and when the ultrasonic vibration is generated, and controls the operation of the bonding tool and the ultrasonic horn based on an analysis result.
