摘要：

This study seeks to quantify the screw-fastening effect of the tool/transducer on wire bonding performance. Aluminum wire bonding experiments were performed on a laboratory test bench. Characterizations of bonding process through a wavelet analysis were used to study the relation between screw fastening, vibration behaviors and bond strength. The time-frequency plots were depicted for identifying un-modeled wire bonding dynamics. Finally some statistically time domain features were presented for further analysis. (C) 2007 Elsevier B.V.
