Claim 1:
2. A temperature control system for devices under test, comprising:
a temperature control zone, which is used for regulating the temperatures of a plurality of devices under test to a specific temperature;
a test plate, including a plurality of test slots for accommodating the plurality of devices under test respectively;
a plurality of temperature-sensing elements, disposed in the test plate and corresponding to the plurality of test slots respectively, the plurality of temperature-sensing elements being used for measuring the temperatures of the plurality of devices under test respectively;
a plurality of temperature control elements, disposed in the test plate and corresponding to the plurality of test slots respectively, the plurality of temperature control elements being used for regulating the temperatures of the plurality of devices under test respectively;
a DUT-transferring device for transferring the plurality of devices under test from the temperature control zone to the test plate, the DUT-transferring device including a transfer temperature control module for regulating or maintaining the temperatures of the devices under test during a transfer process; and
a controller, electrically connected to the test plate, the plurality of temperature-sensing elements, the DUT-transferring device, and the plurality of temperature control elements,
wherein when at least one temperature-sensing element of the temperature-sensing elements detects that the device under test in the test slot corresponding to said at least one temperature-sensing element fails to meet the specific temperature, the controller controls the temperature control element corresponding to the test slot to regulate the temperature of the device under test.
