SEMICONDUCTOR WAFER TEST HANDLER AIR CHILLER


Cold tests are among the most common and crucial tests in semiconductor fabrication. Traditionally, these tests utilize Liquid Nitrogen (LN2) to achieve the necessary low-temperature profiles.

The GT-65 chiller eliminates the need for Liquid Nitrogen in semiconductor testing facilities. This air chiller employs a cascaded refrigeration system, significantly reducing the associated safety hazards. Users can anticipate a Return on Investment (ROI) of approximately one year, contingent upon the type of handlers, loads, and temperature profiles used.
