  • Patent number: 10058019
    Abstract: A bonding apparatus includes: a backup unit including a light-transmissive transmission member having a support surface which supports at least a bonding region of a light-transmissive board from below; a pressure-bonding unit which presses an electronic component placed on the bonding region via a photo-curable adhesive agent; and a light irradiation unit which irradiates the supporting surface with light which promotes hardening of the adhesive agent. The electronic component is bonded to the board by pressing the electronic component mounted on a top surface of the adhesive agent in a state in which light from the light irradiation unit is incident upon the adhesive agent through the supporting surface. The bonding apparatus further includes a light distribution measuring unit which measures a distribution of light from the light irradiation portion in the supporting surface.
