Claim 0:
1. A temperature control method for devices under test, comprising the steps of:
(A) regulating temperatures of a plurality of devices under test (DUTs) to a specific temperature in a temperature control zone;
(B) transferring the plurality of devices under test to a test plate and placing the plurality of devices under test into a plurality of test slots respectively, the test plate including a plurality of temperature-sensing elements and a plurality of temperature control elements, each test slot being correspondingly provided with one temperature-sensing element and one temperature control element; and
(C) measuring the temperatures of the plurality of devices under test in the plurality of test slots by the plurality of temperature-sensing elements respectively, 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 temperature control element corresponding to the test slot regulates the temperature of the device under test;
wherein in the step (B), the plurality of devices under test are transferred to the test plate by a DUT-transferring device, and the DUT-transferring device includes a transfer temperature control module, which is used for regulating or maintaining the temperatures of the devices under test.
