ABSTRACT:
To assure a continuity of bonding by preventing buckling of a covered wire and slipping-off of the covered wire from a second clamper, after a first clamper is closed and the second clamper is opened in a step in which a capillary and first clamper are raised to a ball formation level, the capillary and first clamper are lowered, thus pulling the covered wire downward so that the covered wire does not stick to the second clamper; and then the capillary and first clamper are raised to the ball formation level.
