Abstract :
Vibration in the end of transducer affects the quality of fine pitch thermosonic bonding. Based on the experimental data acquired by laser Doppler vibrometer, vibration coupling along the different directions is analyzed. The bonding tool on/off test was performed to determine the bonding tool´s effect on the transducer vibration. This work can be used for tool length selection for the better performance
