Abstract
A heating element is held in position by a rigid holder constructed to surround an ultrasonic bonding tool and is itself fastened in a fixed position relative to the bonding tool, such that the rigid holder and the heating element are held in close proximity to the bonding tool without physically contacting the bonding tool. This serves to heat the bonding tool, facilitating adequate bonding without overly heating the integrated circuit assembly and without interfering with the critical ultrasonic properties of the bonding tool and ultrasonic transducer horn.
