Appl. No.:

15/006977

Inventors:

- North Reading MA, US
Daniel A. Derringer - San Jose CA, US
Stephen R. Wilkinson - Gilroy CA, US

Assignee:

Teradyne, Inc. - North Reading MA

International Classification:

G01R 31/28
G01R 1/04
G01R 1/44
G01R 1/073

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.

Abstract:

An example test system includes: a pin electronics board for exchanging signals with a device under test (DUT), where the pin electronics board includes first electrical contacts; an interposer between the pin electronics board and a paddle board, where the paddle board includes second electrical contacts, and where the interposer includes electrical connectors for use in establishing electrical pathways between the first electrical contacts and the second electrical contacts; and an actuator configured to force the paddle board and the interposer to make contact so as to cause the electrical connectors to contact the second electrical contacts and thereby establish the electrical pathways.
