Abstract
Provided is a wire-bonding apparatus (10) including: a capillary (28) through which a wire (30) inserted; and a controller (80). The controller (80) is configured to execute operations including: a disconnection operation, after the second bonding operation, of moving the capillary through which the wire is inserted within a horizontal plane vertical to an axial direction of the capillary while the wire is held in the clamped state, and thereby disconnecting the wire from the second bonding point; a preliminary bonding operation of feeding the wire from the second bonding point to a predetermined preliminary bonding point, and performing preliminary bonding at the preliminary bonding point; and a shaping operation, after the preliminary bonding operation, of shaping the wire projecting from a tip of the capillary into a predetermined flexed shape.
