Abstract:
1. An ultrasonic bonding apparatus used to manufacture an electronic device that includes a substrate, an electronic component, and an underfill that is filled in a space between the electronic component and the substrate, said ultrasonic bonding apparatus comprising: a head that includes a tool surface configured to mount the electronic component; a wiping unit configured to wipe out pre-cured underfill that has adhered to the tool surface of the head, by using a wiping member on a wiping table; an ultrasonic bonding unit configured to ultrasonically bond the electronic component with the substrate and to press the head against the wiping member on the wiping table; a detector configured to detect a first pressure applied between the wiping member on the wiping table and the tool surface when the wiping unit provides wiping; and a controller configured to control a second pressure applied by the ultrasonic bonding unit, based on a detection result by the detector.
