In order to clarify vibration characteristics of the horn and capillary system of an ultrasonic wire-bonder, measurements of resonance frequency and mode were carried out with the capillary-tip lightly pressed on simulated work pieces. The results were compared with those in the case of the capillary-tip free, obtained by the previous study, and differences caused by the contact of the capillary-tip with simulated work pieces were made clear. Present and previous results were also considered by theoretical analysis of natural vibration based on a model treating the horn and capillary as beams with tapered portions, and assuming that they were connected at one point.
