CIRCUIT CONNECTION MATERIAL, CIRCUIT MEMBER CONNECTION STRUCTURE, AND CIRCUIT MEMBER CONNECTION STRUCTURE MANUFACTURING METHOD

摘要

The present invention is a circuit connection material for electrically connecting opposing circuit electrodes, comprising an adhesive composition and conductive particles. The conductive particles are aggregated particles with an average particle diameter of 5-20µm, having a metal or nickel core with a Vickers hardness of 300-1000 and an outermost layer of a precious metal coating the core. Unevennesses are formed on the surface of the conductive particles.
