Integrated circuit probing apparatus having a temperature-adjusting mechanism
A probing apparatus for integrated circuit devices comprises a probe card, a probe holder for holding the probe card, a test head and a temperature-adjusting mechanism. The probe card comprises at least one probe capable of forming an electrical connection with the integrated circuit device facing a first surface of the probe card, and the temperature-adjusting mechanism can be positioned on/above a second surface of the probe card. The temperature-adjusting mechanism can be positioned inside the probe card, inside the probe holder or on the probe holder. The test head comprises a plurality of pins configured to form electrical connections with connecting sites of the probe card and test and measurement units and apparatus. The temperature-adjusting mechanism can be positioned on or inside the test head. The temperature-adjusting mechanism comprises a flow line having at least one inlet and a plurality of outlets, and the outlets can be positioned on the second surface of the probe card.
