Description

Technical Field

[0001] The utility model relates to the technical field of chip fixtures, in particular to a radio frequency chip testing fixture. Background Art

[0002] A chip test fixture refers to a production tooling that is used to complete specific parameter tests of packaged chips under specific environmental experimental conditions during the research and development and production process through signal conversion in conjunction with test instruments. When used, existing chip fixtures generally directly restrict the chip through a rectangular ring and then fix the chip, which has poor stability and is prone to falling.

[0003] A BGA packaged radio frequency chip test fixture is disclosed in the patent document with publication number CN218727439U. The chip can be conveniently restricted and clamped by the fixed frame. The fixed frame is supported by the first spring to improve the stability of the chip. At the same time, the chip is contained by the rubber pad to avoid excessive clamping of the chip and damage to the chip. In the process of implementing the technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above-mentioned device is actually used, since the RF chips produced are different and of different sizes, when clamping chips of different sizes, the spring force increases with the increase in compression. Therefore, the clamping effect of the device for RF chips of different sizes to be clamped is different, and it is impossible to adjust according to the size of the RF chip. The clamping force is not stable enough, and stable clamping cannot be achieved, which makes it inconvenient to use.

[0005] Therefore, it is necessary to provide a radio frequency chip test fixture to solve the above technical problems. Utility Model Content
