<p>PURPOSE:To accelerate an operating speed by descending a capillary to a height responsive to data stored in memory means at a high speed, and then descending the capillary at a low speed until it is brought into contact with a bonding face. CONSTITUTION:A driving motor 7 is rotated at a high speed to rotate a bonding head support 13 by a cam 24 at a shaft 14 as a center, and a capillary 2 is descended at a high speed until the capillary 2 is arrived at an initial height. The motor 7 is rotated at a low speed to descend the capillary 2 at a low speed. Data showing the height of a position where the end of the capillary 2 is brought into contact with a bonding face is stored in a RAM 11. The capillary 2 is returned to an original position. The capillary 2 is descended on the basis of data showing the height of the bonding face in contact with the capillary 2 in the case of a previous wire bonding, and bonded. Thus, its operating speed is accelerated.</p> |
