The conductive balls are coated with a core-shell-structured emulsion-phase or suspension-phase or water-dispersible resin to form insulation resin layers as the shells of the insulation resin layers are coated with resin layers having the water-emission ability. Also disclosed are methods of manufacturing anisotropic conductive balls for electric connection as well as the products using them. Although the surfaces of the anisotropic conductive balls are coated with single- or multi-layered insulation resin layers, they show superior alive and insulation characteristics. | 10-02-2008 |
