Abstract
Abstract A method for arranging conductive particles on electrodes of a substrate, which electrically connect with electrodes of an electric part via the conductive particles. An adhesive layer is formed on the electrodes. Conductive particles are arranged on the adhesive layer in a predetermined pattern. Then, the conductive particles on said electrodes of a substrate are affixed thereon.
