摘要 |
A position drive for a wafer in a system for testing of integrated circuit components of the wafer includes a first drive assembly for quick lifting of a wafer-supporting member towards testing probes, second drive assembly for positioning the wafer-supporting member in two stable positions in a vertical direction for compensating thickness allowances of the wafers to be tested and a third drive assembly for mechanical rotation of the wafer-supporting member through any required angle. |
