Patent ID: 8119449

Claim:
A method for manufacturing an electronic part mounting structure, comprising: forming a protruding electrode made of a conductive resin including a photosensitive resin and a conductive filler on an electrode terminal of an electronic part or on a connection terminal of a substrate; positioning the electronic part or the substrate on which the protruding electrode is formed so that the electrode terminal and the connection terminal face each other with the protruding electrode interposed therebetween; and connecting the electrode terminal and the connection terminal with the protruding electrode interposed therebetween by pressing the electronic part, wherein the forming of the protruding electrode comprises: supplying a liquid resin including a photosensitive resin and a conductive filler to a container through which at least light transmits a bottom thereof; immersing an electronic part where a plurality of electrode terminals are formed on one surface into the liquid resin in such a direction that the electrode terminal faces the bottom and has a predetermined distance relative to the bottom; forming a first layer collectively on top of a plurality of the electrode terminals by curing the liquid resin on the electrode terminal through selective irradiation with light via a first opening of a photo mask from the bottom of the container; pulling the electronic part up from the bottom by a predetermined distance; forming a second layer on the first layer by curing the liquid resin on the first layer through selective irradiation with light using a photo mask having a second opening which is smaller than the first opening; and forming the protruding electrode having a layer structure by repeating the pulling of the electronic part and the forming of the second layer sequentially.
