Abstract:
1. A method of mounting a conductive ball, comprising the steps of: disposing a mask on a substrate including connection pads, the mask having opening portions corresponding to the connection pads; supplying conductive balls on the mask; arranging the conductive balls on the connection pads of the substrate through the opening portions of the mask, by moving the conductive balls to one end side of the mask by a ball moving member; and placing a ball removal film at a predetermined height position, wherein the ball removal film is in contact with excess conductive balls remaining on a region of the mask where the opening portions are provided, the ball removal film does not contact the conductive balls on the connection pads of the substrate, and the ball removal film does not contact the conductive balls moved to the one end side of the mask by the ball moving member; removing the excess conductive balls remaining on the region of the mask where the opening portions are provided, by bonding the excess conductive balls to the ball removal film.
