Abstract
In order that, on wire bonding by means of a Wire Bonder, optimum bonding results can be achieved after a capillary change it is suggested that, after a change from a first capillary to a second capillary, the ultrasonic transducer which applies ultrasonics to the horn which guides the capillary is controlled with a parameter P which results from the parameter P before the capillary change as P =g(k , k )*P or P =g(k , k , A , A )*P or P =g(k , k , A , A , H , H )*P , whereby the quantities k and k designate the estimated values for the flexural strength, the quantities A and A the amplitudes of the freely oscillating capillary and H and H the diameters in the narrowest part of the longitudinal drill hole of the first or second capillary and whereby the function g is a predetermined function.
