PURPOSE:To form an ideal wire loop and to prevent a wire from being damaged by a method wherein a reversing action is set as an arc action whose center is situated at a wire neck part or near the wire neck part at a first bonding point. CONSTITUTION:Tn a state that a clamper which clamps a wire 1 is opened, the wire 1 is connected to a first bonding point A; after that, a capillary 2 is raised up to a point B. After the capillary has been stopped once or instantaneously at the point B, the capillary 2 executes a reversing action as an arc action at a radius of R whose center is situated at a wire neck part 1a or near the wire neck part 1a; the capillary is then moved to a point C. Since the reversing action is set as the arc action whose center is situated at the wire neck part la or near the wire neck part 1a, the capillary 2 does not trail the wire 1. Thereby, an ideal wire loop is formed, the capillary 2 does not trail the wire 1 and the wire is not damaged. |
