Fine conductive particles for making anisotropic conductive adhesive composition

摘要

Fine conductive particles are composed of metallic conductive powder, and an insulating organic capping layer on the grains of the powder. The metallic conductive powder have grains with a diameter ranging from 1 to 20 microns, and the capping layer has a thickness of 50-400 nm, which is able to flow by thermo-pressing. The insulating organic capping layer is prepared from a silane having a reactive functionality, a fluorine-containing silane and a compound or a resin having a functionality able to reactive with the reactive functionality.
