Title: METHOD FOR SELECTIVELY COATING ELECTRONIC COMPONENT WITH COATING MATERIAL, AND METHOD FOR MANUFACTURING ELECTRONIC COMPONENT
Abstract:
Provided is a method for selectively coating an electronic component with a coating material, with which it is possible to collectively coat a large number of electronic component elementary bodies with the coating material. This method is for coating, with the coating material, only a surface material selected from among a plurality of surface materials exposed on the surface of the elementary body and made of different materials, the surface material to be coated with the coating material being defined as the selected surface material and the surface material that not to be coated with the coating material being defined as the non-selected surface material. The method is sequentially provided with: an elementary body preparation step for preparing an elementary body (multi-layer capacitor 1), in which the selected surface material (component body 2 made of a ceramic) and the non-selected surface material (external electrodes 3a, 3b made of a metal) are exposed on the surface; a surface modification step for applying a surface modification agent (silane coupling agent 4) to only the surface of the selected surface material from among the surfaces of the elementary body; and a coating step for coating a coating material (polymer resin 7) onto the surface of the selected surface material to which the surface modification agent has been applied.
