Abstract:
1. A method for IC wirebonding comprising the steps of: bringing a first capillary of a dual capillary bond head to bear on a plurality of bond targets on an IC package assembly, the first capillary affixed to an ultrasonic horn; dispensing a first wire from the first capillary and attaching one or more first bond wires to selected bond targets; and then rotating the ultrasonic horn thereby displacing the first capillary and bringing a second capillary affixed to the ultrasonic horn and at a fixed acute angle with respect to the first capillary to bear on a plurality of bond targets on the IC package assembly; and dispensing a second wire from the second capillary and attaching one or more second bond wires to selected bond targets.
