| 摘要 |
The invention relates to methods for positioning of a substrate and contacting of the test object for testing with a test apparatus with an optical axis and corresponding devices. Thereby, the substrate is put on the holder. The substrate is positioned relative to the optical axis. A contact unit is also positioned relative to the optical axis, whereby the contact unit is positioned independent of the positioning activity of the substrate. Thereby, a flexible contacting of test objects on the substrate can be realized.
