Abstract:
1. A method of bonding flying leads that aligns the respective flying leads with respective substrate pads out of a plurality of substrate pads disposed in parallel and applies ultrasonic vibration to the flying leads using a bonding tool to bond the flying leads to the substrate pads, wherein a bonding tool including a vibrating body is used in which plural contact members, which contact the flying leads and apply the ultrasonic vibration, are rotatably supported on the vibrating body, and in a state where the plural contact members roll while in contact with the flying leads, the bonding tool moves in a direction so as to cross the flying leads disposed in parallel and the ultrasonic vibration is applied from plural contact members to the flying leads to ultrasonically bond the respective flying leads to the substrate pads.
