CONDUCTIVE PARTICLE, ANISOTROPIC CONDUCTIVE ADHESIVE FILM AND CONNECTING STRUCTURE

摘要

The present invention relates to conductive particles comprising: a plastic nucleating agent; mother particles which are coated on the surface of the plastic nucleating agent and have a conductive layer with a nickel/phosphorus alloy layer; insulative child particles which are coated on the surface of the mother particles. The particle diameter of the mother particle is 2.0-3.0 um. The saturation magnetization of the mother particles is 45 emu/cm3 or less. The particle diameter of the insulative child particle is 180-500 nm.
