Abstract

In recent years, ultrasonic wave has been widely employed in many industrial applications. The ultrasonic horn is the key component of ultrasonic equipment. Because of its complicated geometry, exact solutions cannot be easily obtained for the ultrasonic horn. Numerical technique such as finite element method (FEM) can be used; however, the validity of its results must be verified. Methods of experimental mechanics thus become indispensable not only for solving problems but also for verification purpose. In this paper, two novel applications of experimental mechanics on the design of two ultrasonic horns, i.e. horn I and horn II, for ultrasonic welding and flip-chip bonding are reported.
