Multiple contact probes

1. An apparatus for testing a device under test comprising:

a probe array for probing a plurality of contact pads disposed on the device under test;

a first gas flow apparatus and a second gas flow apparatus, said first gas flow apparatus disposed on a first side of said probe array and said second flow apparatus disposed on a second side of said probe array; and

said gas flow apparatus providing gas flow around and through said probe array.

2. The apparatus of claim 1 wherein said gas flow apparatus comprises a gas nozzle array.

3. The apparatus of claim 2 wherein said gas nozzle array comprises openings.

4. The apparatus of claim 2 wherein said gas nozzle array comprises slots.

5. The apparatus of claim 1 wherein said gas flow apparatus comprises acoustic excitation to increase gas flow turbulence.

6. The apparatus of claim 1 wherein said gas flow apparatus comprises pulsed gas flow.

7. The apparatus of claim 1 wherein gas from said first gas flow apparatus flows in an opposite direction of gas from said second gas flow apparatus.

8. The apparatus of claim 1 wherein gas from said first gas flow apparatus flows in a perpendicular direction to gas from said second gas flow apparatus.

9. The apparatus of claim 1 wherein said first gas flow apparatus operates at positive pressures and said second gas flow apparatus operates at negative pressure.

10. The apparatus of claim 1 wherein said gas flow is turbulent.

11. The apparatus of claim 1 further comprising a cooler that cools said gas flow to substantially below room temperature.

12. The apparatus of claim 11 wherein said cooler comprises a Peltier cooler.

13. A method for testing a device under test comprising:

probing a plurality of contact pads disposed on the device under test;

disposing a first gas flow apparatus on a first side of the probe array and disposing a second flow apparatus on a second side of the probe array;

flowing gas from the gas flow apparatus around and through the probe array; and

circulating the gas in a predetermined gas flow configuration.

14. The method of claim 13 further comprising acoustically exciting the flowing gas to increase gas flow turbulence.

15. The method of claim 13 further comprising pulsing gas from the gas flow apparatus.

16. The method of claim 13 comprising flowing gas from the first gas flow apparatus in an opposite direction from the gas flowing from the second gas flow apparatus.

17. The method of claim 13 comprising flowing gas from the first gas flow apparatus in a perpendicular direction from the gas in the second gas flow apparatus.

18. The method of claim 13 further comprising operating the first gas flow apparatus at a positive pressure and operating the second gas flow apparatus at a negative pressure.

19. The method of claim 13 further comprising cooling the gas flow to substantially below room temperature.

20. The method of claim 13 wherein the flowing gas comprises a velocity of approximately 0.5 to 10 ft/s.
