Low temperature test of semiconductor devices assisted by ultra-low refrigerated circulators

Recirculating chiller is a kind of circulating refrigeration equipment that can provide low-temperature liquid and low-temperature environment. It not only covers a small area, safe and fast, but also has fast refrigeration speed. When semiconductor devices need low-temperature test, it can play a role quickly.

Circulation chiller uses medium to cool down quickly, generally alcohol. It quickly cools the alcohol through the circulation system and delivers it to the place where it is needed to provide its low-temperature environment. When the alcohol temperature rises, it will pump the heated water back, refrigerate and deliver it again to ensure that there is always a low-temperature environment.

The low-temperature tests required for semiconductor devices include low-temperature storage test, temperature impact test, temperature and humidity bias test, etc. These tests are very important. They are related to whether the semiconductor component can be used normally, whether it will be directly damaged in some cases, and its service life.

During the test, you can find a container to put the semiconductor devices inside or outside, then connect the pipeline, set the temperature for the ultracool circulation chiller and cool it, and you can safely wait for the end of the test time. Of course, please remember to turn off the power and maintain the equipment after the test.
