The testing stations 12 are used to place chips, and each chip can be tested through the testing board 11 .

[0036] The chip test temperature control device also includes a temperature control device 20, which includes a test machine 21, a temperature controller 22, a blowing system 23 and a plurality of temperature sensors 24. Among them, the temperature sensors 24 correspond to the test stations 12 one by one, and the temperature sensors 24 are arranged in the test stations 12 corresponding thereto, so that the temperature sensors 24 can perform real-time temperature detection on the test stations 12 corresponding thereto, that is, the temperature sensors 24 can detect the real-time temperature of the test stations 12 corresponding thereto, and the temperature sensors 24 are connected in communication with the test board 11, and the temperature sensors 24 can transmit the real-time temperature of the test stations 12 corresponding thereto detected by the temperature sensors 24 to the test board 11.
