Legendary reliability and low noise capability started the vortex cooling revolution.
- No liquids or Peltier elements
- MTBF > 50,000 hours
- Temperature ranges from -10 to +300 °C
The ERS AirCool® chuck system was a breakthrough product that introduced the use of pressurized air for active cooling of wafers well below ambient temperatures on the thermal chuck. Because it uses no Peltier elements or fluids inside the chuck, it has become a synonym in the industry for uncompromising reliability and high temperature stability.
The AirCool® chuck system has proven particularly suitable for low noise test due to its quiet air-only operation and high insulation. Its elegant construction made it ideal for extreme high temperature test as well as for the development of highly planar surfaces and high-voltage applications.
With the introduction of the AirCool® system, MTBF values of more than 50,000 hours became reality. With the onset of high pin-count wafer test, ERS® introduced the “High-Rigid” version of the AirCool® system meeting the demands of the users of high pin-density probe cards. The demand for this air-only system was such that fully integrated applications for all major automatic probers were soon in the field.
