The test rack 3 can use a test bracket of the prior art according to the test requirements, which is used to dock with the test equipment to facilitate the performance test of the chip product 8 under pressure.

[0020] The size and shape of the pressure nozzle 6 can be adaptively selected according to the different packaging types of the chip product 8, so that it can apply the pressure required for the test to the chip product 8, and is used to simulate the state of the machine press test to meet the subsequent performance and other test requirements of the chip product 8. The pressure of the pressure nozzle 6 on the chip product 8 is adjusted by tightening the turntable 7, so that it can meet different test requirements, and there is no need to configure multiple test equipment according to different packaging types of the chip product 8, thereby reducing equipment investment.

[0021] Please see attached Figure 1 To Attachment Figure 3 The fixed bracket includes a base 101, a first pillar 102 and a second pillar 103; the first pillar 102 and the second pillar 103 are respectively vertically arranged on the base 101, one end of the test frame 3 is arranged on the top of the first pillar 102, and the other end of the movable bracket 5 is rotatably arranged on the top of the second pillar 103.
