PURPOSE:To prevent a bonded part from peeling off and suppress dispersion of tail lengths by cutting a wire by moving a tool backward with a clamp closed after bonding at a second bonding point. CONSTITUTION:After a wire 5 is bonded at a second bonding point, a tool 3 is moved backward with a clamp 4 closed to cut the wire 5. Therefore, force upward will not act on the wire 5 to prevent the bonded part of the wire 5 from peeling off. After the tool 3 is raised and the wire 5 is sent out of the tip of the tool 3, the sent-out part of the wire 5 is shaped by bending by moving the tool 3 diagonally to the lower behind to always obtain tails of a constant length equal to the length of the sent-out part. This prevents the bonded part from peeling off and suppresses dispersion of the lengths of the tail at the tip of the tool. |
