Patent ID: 7083077

Claim:
A bonding system for producing an electrical connection between a first contact surface and a second contact surface, comprising: a programmable control unit; a bonding capillary including a capillary nozzle, the capillary nozzle having an annular protuberance; a deformed first ball placed on a contact point on the first contact surface; and a contact wire via which a bond connection is produced between the first contact surface and the second contact surface, using the deformed first ball on the first contact surface and a second contact connection on the second contact surface, a second ball being positioned on the second contact connection using the capillary nozzle and being deformed by compression using the capillary nozzle, wherein the programmable control unit is programmed to control the positioning of the second ball and the steps of: after the compression of the second ball, the capillary nozzle is lifted off the deformed second ball and moved according to a lateral movement, the lateral movement is in a direction away from a direction vector of a longitudinal extension of the contact wire, after the lateral movement, the capillary nozzle is moved in a direction of the second contact surface, so that the annular protuberance strikes the deformed second ball, and a further plastic deformation of the deformed second ball is brought about by an outer surface of the annular protuberance, under an influence of an applied contact force F′, and under an influence of an ultrasonic operation.
