  • Automatic test system with focused test hardware
    Patent number: 10139449
    Abstract: A tester interface unit comprising a test hardware module. The test hardware module may have a simple construction, relying on control and/or signal processing in one or more tester instruments to generate or analyze test signals for a device under test. The test hardware module may be disposed within the tester interface unit, providing a short and high integrity signal path length to the device under test. The tester interface unit may include a purge gas chamber and a cooling chamber, with the hardware module penetrate a separator between those chambers, sealing an opening between the purge gas chamber and the cooling chamber. A heat spreader may move heat generated on the portion of the test hardware module in the purge gas chamber to the cooling chamber.
