Abstract
To assure the continuity of bonding by preventing any buckling of a covered wire or slipping-off of the covered wire from a second clamper, the second clamper is caused to vibrate while a capillary and first clamper are being raised to a ball formation level after the first clamper is closed and the second clamper is opened in the step of raising the capillary and first clamper to the ball formation level, thus preventing the covered wire from sticking to the second clamper.
