    Abstract: An improved system is provided for positioning a circuit board with respect to wire handling and bonding apparatus. The board is movable in an X-Y plane, can be raised or lowered along a Z dimension axis, and can be rotated about the Z dimension axis. Separate X, Y, Z, and rotational dimension electric motors are mounted on a stationary base. A differential mechanism couples an X positioning mechanism to respond to the difference between the X dimension motor position and the rotational dimension motor position. The differential mechanism prevents changes in the rotational position of the X positioning mechanism from affecting the X dimension position. A similar differential mechanism couples the Y positioning mechanism to the Y drive motor and to the rotational dimension drive motor.
