Abstract
A single point bonding apparatus and method for bonding one electrical conductor to a second electrical conductor by a thermosonic process using force, time, temperature and ultrasonic energy as the key parameters in forming the bonds. A bonding tool has a tip with a multiple of nonparallel surfaces extending from the end of the tip for maximizing the amount of ultrasonic energy coupled to the electrical conductors. The surfaces may be recessed into the end of the tip or protrude outwardly from the end of the tip for coupling ultrasonic energy in directions both parallel and perpendicular to the conductors.
