CONSTITUTION:A bonding head 6 is provided on an X-table 11 and a Y-table 12 and each table is connected to motors 13, 14. The motors 13, 14 are driven by a program made with the driving system 15 and the control system 16 of the X-Y tables. The position of bonding is recognized by a TV camera. The control system 16 which has the function of a computer controls the X-Y tables and the Z axis of the bonding head and if the stop of bonding is detected, the bonding head 6 is immediately made to retreat to be protected against the heat for heating a lead frame 2. |
