Compression Testing and Observation of Deformation of Bonding Wire Au Balls by Shimadzu MCT-W500 Micro Compression Testing Machine

Introduction

Broadly speaking, there are two types of wire bonding, thermocompression and thermosonic. Of these two methods, thermosonic bonding has become the most commonly used method. For this reason, it has become important to grasp the relationship between bonding force and displacement (deformation). The following introduces an example where we performed a compression test on the Au ball at the end of a bonding wire, investigated the relationship between force and displacement, and observed the progress of deformation from the side.
