Title:
POLYMERIC MICROPARTICLES, CONDUCTIVE MICROPARTICLES, AND ANISOTROPIC CONDUCTIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/020799
Kind Code:
A1
Abstract:
Conductive microparticles with which a broad connection area can be obtained at a low pressure are provided. The purpose of the present invention is to provide an anisotropic conductive material containing conductive microparticles such as those mentioned above. In addition, polymeric microparticles that can be suitably used as cores for such conductive microparticles are provided. These polymeric microparticles are characterized in that the breaking point load is not more than 9.8 mN (1.0 gf). These conductive microparticles are characterized by having a conductive metal layer on the surfaces of the polymeric microparticles. This anisotropic conductive material is characterized by containing the conductive microparticles.
