PURPOSE:To protect the surface of a metal small gauge wire from damage by allowing a capillary to move freely even at any angle when moving said capillary to a second wire bonding site after having wire-bonded a first wire bonding site. CONSTITUTION:There are provided a metal small-gauge wire 3 made of gold, aluminum or the like and a capillary tool 4 having a hollow hole, which guides the metal small-gauge wire 3. After having wire-bonded a first wire bonding site, the capillary tool 4 is carried to a second wire bonding site. The capillary tool 4 is moved on the slant at a specified angle in parallel to a transfer direction. At the second bonding wire site, the capillary is posture-converted to the initial state and wire-bonded. This construction makes it possible to protect the surface of the metal small-wire gauge from damage by a corner section of a metal small-gauge wire take out port of the capillary tool 4. |
