Abstract:
1. An ultrasonic bonding apparatus used to manufacture an electronic device including 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 including a tool surface configured to mount the electronic component; an ultrasonic bonding unit configured to ultrasonically bond the electronic component with the substrate; and 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, wherein the ultrasonic bonding unit includes: a first driver configured to drive the head in a direction in which the electronic component is pressed upon the substrate; and an ultrasonic generator configured to apply an ultrasonic wave in a plane orthogonal to the direction, and wherein the wiping unit includes: a wiping table used to wipe out the tool surface; a feed mechanism configured to supply the wiping member to the wiping table and to roll up the wiping member so that an exposed part of the wiping member which exposes on the wiping table can change; a cartridge configured to house the wiping table and the feed mechanism; and a second driver configured to drive the cartridge in the plane, wherein the first driver is configured to press the head upon the wiping member on the wiping table.
