Abstract:
1. A bonding device for bonding an electronic component to a substrate, comprising: holding/releasing means for releasably holding a solid bonding member at a position spaced apart by a predetermined distance from a bonding position on the substrate to which the electronic component is bonded; ejecting means for ejecting the bonding member onto the bonding position; heating means for heating the bonding member by applying heat radiation to impart heat to the bonding member; and control means for synchronizing releasing of the holding by the holding/releasing means and the heating by the heating means, wherein, after releasing the holding of the bonding member by the control means, the bonding member is heated to thereby bond the electronic component to the bonding position on the substrate, wherein the holding/releasing means effects the holding or the releasing of the bonding member by a direct-acting system, a pivoting system, or a swiveling system, and wherein the holding/releasing means has a nozzle assembly with an opening and an opening/closing member for opening and closing the opening, and wherein the opening/closing member is driven by a piezoelectric actuator.
