Automatic Test Equipment

Automatic Test Equipment Description:

Automatic Test Equipment from Wewon Environmental Chambers Co., Ltd. use PID + PWM principle VRF technology (electronic expansion valve servo control of refrigerant flow according to thermal conditions). The heater does not work at low temperature, The refrigerant flow and flow direction are regulated through PID+PWM, Three – way flow adjustment for refrigeration pipe, cold bypass pipe and hot bypass pipe.

Automated Test Equipment (ATE) adopts PID+PWM principle VRF (Refrigerant flow control) technology to realize low temperature and energy saving operation (servo control technology of refrigerant flow based on thermal condition of electronic expansion valve). Realize the automatic constant temperature of the studio.

This method can reduce energy consumption by 30% at low temperature. The technology is based on ETS series electronic expansion valves from Danfoss, Denmark. It is suitable for smooth adjustment of cooling capacity when different cooling capacity is required. In other words, Automatic test equipment for semiconductor reliability testing can adjust the refrigerating capacity of the compressor at different cooling rates.
