The electric characteristics connected by anisotropic conductive adhesive film were significant affected by the deformation of the conductive particle. In this study, the theory model was set up to calculate the conductive particle resistance after ACF bonding. The effects of the deformation of the conductive particle on its resistance were analysis. The result compared with the experiments was fit well. The rebound of the conductive particle under the high temperature and humidity environment was simulated using FEM, and the deformation was determined. The effects of the rebound of the conductive particle of ACF on its resistance were investigated, and the effects of the number of the conductive particle on the total electrical properties were also studied. The optimal deformation of the conductive particle connected by ACF and the effects of the thermal and humidity ambience on its electric characteristics were obtained.
