A composite two-dimension ultrasonic vibration system with parallel structure is presented in this paper for the wire bonding application. Compared with other conventional structures, this one uses the structure of the clamping beam, weakening the horizontal deflection stiffness, instead of the clamping ring, which weakens the coupling effects existing in(More)
A composite ultrasonic energy transmission system with the serial structure horn is presented for the wire bonding application. Compared with the conventional parallel structures, this one can greatly reduce the structural coupling effect. Energy density formulation is deducted theoretically. Through the vibration characteristic analysis and FEA(More)
