The core equipment - outer lead bonding equipment, is used to stick chip on films on the display, connecting the circuits with driver IC and liquid crystal displays. However, due to the scale of several micrometers in circuits, the vibration problems in the equipment caused by bonder motions, bonding process and material transports significantly affect the accuracy in sticking process, and they are no longer negligible. In this study, the finite element method is used for the dynamic analysis in outer lead bonding equipment. The goal is to investigate the vibration at the base structure of the equipment undergoing material transports. We propose improvements after finding out the vibration problems in dynamic response by numerical simulation. This study firstly uses a finite element software ANSYS to carry out the static and dynamic analyses of the base structure. The measurements of vibration are taken by laser sensor and accelerometer. The finite element model is in turn compared with measured results and modified. Finally, an improved design is proposed.
