Temperature Testing

Thermal Chambers

The X-ES environmental testing lab is outfitted with the following thermal chambers:

  • Envirotronics EV92-LN2
  • Thermotron SE-600 chambers
  • Thermotron SE-300 chambers
  • Thermotron FA35

With these thermal chambers, X-ES engineers can:

  • Perform operational temperature tests (for example: -40°C to 85°C for Ruggedization Level 5 products).
  • Perform non-operational (or storage) temperature tests (for example: -55°C to 105°C for Ruggedization Level 5 products).
  • Monitor temperatures at multiple points of interest via calibrated DAQ systems.
  • Independently control the temperature of the thermal interface surface (for Ruggedization Level 5 products).
  • Utilize liquid nitrogen (LN2) cooled fixtures to control the thermal interface temperature of conduction-cooled systems.

Low Temperature Testing

X-ES is capable of performing low temperature testing to replicate operational and non-operational environmental conditions.

  • Operational: Perform cold-boots or low temperature operation per the ruggedization level of the product.
  • Non-Operational: Perform non-operational storage temperature testing.

High Temperature Testing

X-ES is capable of performing high temperature testing to replicate operational and non-operational environmental conditions.

  • Operational: Perform stress tests at the maximum operating temperature to verify performance and functionality.
  • Non-operational: Perform non-operational storage temperature testing.

Temperature Shock

Temperature shock applies stress to products due to the difference in thermal expansion coefficients of various materials in a system. Operational and non-operational testing is possible.

LN2

X-ES utilizes liquid nitrogen (LN2) in support of temperature testing.

ESS

Manufacturing has temperature chambers that are located in an ESD-protected area and dedicated to manufacturing testing.
