Abstract: The invention relates to a positioning device for the production of semiconductor components, particularly for wire bonding apparatuses, which positioning device is comprised of a cross table and separate x-direction and y-direction drive units.According to the invention, the two drive units, each comprised of a drive motor with an excursion measuring system (1; 17) affixed to the frame via a support plate (2; 18) are disposed in a parallel orientation. Each support plate (2; 18) also bears a bearing (3; 19) for a drive spindle (5; 20). A drive nut (6; 22) is disposed on the drive spindle (5; 20), where the nut is nonrotatably fixed. A vertical bearing (8) is mounted on the support plate (2), which bearing bears two adjustable levers (9, 11) oriented at a mutual 90.degree. angle, wherein the lever (9) is connected to the drive nut (6), and the lever (11) is connected to a x-direction guide a mechanism.
