Abstract
The present invention provides a solder ball bonding method and a solder ball bonding apparatus, which can enhance efficiency of bonding processing and in which plural electrodes formed on objects to be bonded are bonded to each other by melting a solder ball. In the present invention, the solder balls are picked up by a pick-up nozzle having a plurality of pick-up openings corresponding to electrode areas on the objects to be bonded and the solder balls are conveyed on the electrode areas. A laser radiating unit disposed independently above the pick-up nozzle is shifted along an arrangement direction of the pick-up openings and a laser beam from the laser radiating unit is irradiated onto the solder ball through a transparent member of the pick-up nozzle and through the pick-up opening of the pick-up nozzle, thereby melting the solder ball on the electrode area.
