PURPOSE:To form an excellent wire loop by making a magnetic field interfere in magnetic flux generated by flowing currents through a bonding wire and sucking the bonding wire in the direction rectangular to an axial center. CONSTITUTION:Currents are flowed between a terminal 14 and a feeder terminal 8 at the terminal of a bonding wire 6 while using a wire guide 3 arranged on the upper side of a wire hold-down 4a as the terminal 14. An electromagnet 15 as a magnetic field generating means is disposed at the center on the side adjacent to the bonding wire 6 at a proper distance. A generated magnetic field interferes in magnetic flux generated around the bonding wire 6 by flowing currents through a coil 15a for the electromagnet 15 under the state in which currents are flowed through the bonding wire 6, the bonding wire 6 is sucked, and tension is obtained. |
