The objective of this study is to study the mode shape and natural frequency of the dry film lamination pre-cut device of a semiconductor wafer vacuum modeling machine. The Pro/E is employed to construct the 3D model and do the modal analysis. The simulation result is verified by modal test. The spectrum analyzer, three-axis accelerometer and percussion hammer are used to obtain the testing data. The results of this study should guide to better future designs of the equipment and are vital to reliable and safe operations of these devices.
