temperature control

active thermal control (ATC) option

  • closed loop temperature control with sensor integrated in temperature head
  • highest accuracy due to direct temperature measurement at heatsink in conductive contact with device
  • high IC power dissipation controllable during electrical test
  • software-operated air flow control system with HMI feedback included
  • change of set temperature from tester via GPIB or RS232
    • fine adjustment during testing possible
    • single-insertion at multiple test temperatures possible
    • multiple tests at different set temperatures without user interaction possible
  • fully integrated, handler-software-controlled cooling unit offering choice of two configuration options
    • electrical air chiller
      -40 °C (-40 °F) DUT junction temperature system specification
    • LN2 heat exchanger
      -60 °C (-76 °F) DUT junction temperature system specification
  • system interior sealed and purged to prevent icing
  • modular, expandable temperature system
