ABSTRACT:
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.
