Patent ID: 8025205

Claim:
An electronic component mounting method for electrically connecting bumps formed on an electronic component to electrodes formed in an electronic component mounting region on a board by metal bonding, comprising: placing a liquid thermosetting resin in a liquid glob state on a surface of the board so that one portion of the thermosetting resin is arranged inside the electronic component mounting region and a remaining portion of a liquid measure of the thermosetting resin greater than that of the one portion is arranged outside the electronic component mounting region; after said placing of the liquid thermosetting resin, moving down a thermocompression bonding head which holds the electronic component to the board, and then bringing a bump formation surface of the electronic component into contact with the one portion of the thermosetting resin in the liquid glob state while pressurizing the bumps against the electrodes of the board; carrying out metal bonding of the bumps and the electrodes by heating the electronic component by the thermocompression bonding head in a state in which the bumps are pressurized against the electrodes, while heating the thermosetting resin so that entry of the thermosetting resin in the liquid glob state into a gap between the board and the electronic component in the electronic component mounting region is promoted and thermosetting reaction of the thermosetting resin which has entered the gap is promoted, thereby bonding the electronic component to the board via cured thermosetting resin; and then moving the thermocompression bonding head away from the electronic component, thereby mounting the electronic component on the board.
