[0002] With the rapid development of semiconductor technology and the increasing complexity of chips, chip testing has been carried out throughout the entire design, development and production process. Aging testing is an important test used to eliminate early failure products before the chip is delivered to customers.

[0003] Currently, the chip needs to be loaded into a carrier before the chip aging test. Therefore, when loading and disassembling the chip, an auxiliary fixture is required to carry out the chip loading and unloading operations. During use, auxiliary alignment deviations are likely to occur, and the test seat is easily damaged during the downward pressure process.

[0004] Based on this, the utility model designs a floating auxiliary fixture for loading and unloading to solve the above problems. Utility Model Content

The shaft seat 705 is fixedly connected to the main rod body 706. The lower end of the main rod body 706 is provided with a wheel groove 707, and a roller 708 is movably installed in the wheel groove 707.

[0028] The upper end of the main rod body 706 is movably installed in the fixed seat 7011, and the fixed seat 7011 is fixedly connected to the outer side wall of the floating fixture 5.

[0029] A rectangular plate 709 is provided on the inner side of the main rod body 706 , and a second spring 7010 is provided on the rectangular plate 709 . One end of the second spring 7010 is fixedly connected to the rectangular plate 709 , and the other end is fixedly connected to the outer wall of the floating fixture 5 .

[0030] The four clamping assemblies 7 provided in the floating fixture 5 can assist in centering the clamped chip, and at the same time have a certain degree of floating ability during use to adapt to the irregular shape and size of the workpiece.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 6 The four corners of the upper end of the floating jig 5 are fixedly connected with sliding rods 3, and the sliding rods 3 are all slidably connected to the base body 1. A limiting block 4 is provided at the top of the sliding rod 3. The outer side of the sliding rod 3 is wrapped with a first spring 6.
