Technical Field

[0002] With the development of economy and the continuous improvement of science and technology, my country's semiconductor industry has developed more and more rapidly, and the use of semiconductor chips has also increased. Semiconductor chips: semiconductor devices that can realize certain functions are made by etching and wiring on semiconductor sheets. When processing semiconductor chips, users will extract any semiconductor chips for testing. However, when testing semiconductor chips, in order to ensure the stability of the test, auxiliary positioning devices are needed to limit and fix the semiconductor chips for subsequent testing.

[0003] However, most of the auxiliary positioning devices now have the following problems:

[0004] For example, a positioning device for chip detection with announcement number CN214409209U can easily limit the chip, but the chips are divided into different sizes, and there are square and rectangular chips. It is inconvenient to fix the rectangular chips during installation, and only the two sides of the chip can be limited. The fixing stability is poor, and it is inconvenient to limit and fix chips of different sizes; at the same time, after the chip is positioned, it is clamped by a single clamp, which makes it impossible to adjust it. The position is limited, and the detection angle of the chip is fixed. If the angle needs to be adjusted during detection, it is troublesome, and it is inconvenient to easily rotate and adjust the fixed chip.

[0005] Therefore, we make improvements to this and propose an auxiliary positioning device for semiconductor chip detection. Utility Model Content
