step c, heating the second chip: moving two sliding seats (2) in the horizontal direction to be close through the base (1), and keeping the two sliding seats (2) in the vertical direction away until the heating socket (4) is contacted with a chip seat (6) where the second chip is positioned, heating the second chip through the heating socket (4), contacting the cooling socket (5) with the chip seat (6) where the first chip is positioned, and cooling the first chip through the cooling socket (5);
step d, temperature cycling: repeating the step b and the step c until the test is completed.
