The deformation of conductive particles in pure metal connected by anisotropically conductive adhesives has been investigated using finite element analysis. The results indicate that the increment in stresses of the conductive particles begins at the contact area toward the boundary through the centers of conductive particles when the reduction in height increases. When stress is over the yield strength, the similar behavior was observed. So the deformation of conductive particles is not uniform, which means that the deformation of conductive particles is the same as the stress does.

采用有限元模拟分析了各向异性导电胶连接的纯金属导电颗粒的变形过程，研究结果表明，随着压下量的增加，导电颗粒的应力增加由接触面开始，经中心区域向导电颗粒的周边扩展，大于屈服强度的应力变化与此相似，因此导电颗粒的变形是不均匀的，即导电颗粒的变形由接触面开始，经中心区域向周边区域进行。
