摘要：

Metal-coated polymer particles are used as a critical component in anisotropic conductive adhesives. The mechanical properties of polymer particles are of crucial importance to both application and design. In this study, a nanoindentation-based flat punch test approach has been developed to determine the mechanical properties of two polymer particles. Particle A failed at an average deformation of 67.2%, while no failure was observed for particle C when a maximum 10 mN normal load was applied. The contact stress strain behavior and contact modulus were obtained from the flat punch test.
