Description

Technical Field

[0001] The utility model relates to the technical field of DFN device testing, in particular to a novel test socket. Background Art

[0002] In the DNF production process, device performance testing is an essential part. By testing the performance of DFN devices after production, problems in the DFN device production process can be discovered in time so that they can be improved in time.

[0003] At present, when testing the performance of standard DFN devices, only a standard test socket is needed to achieve the corresponding measurement. However, DFN37.9x23.8 type DFN devices are fully customized integrated circuit packages. There is no test method on the market that can perform batch testing on them without damaging the device pins. If the traditional method is used, the device needs to be soldered on the SMD board for testing. The device pins will definitely be damaged and cannot be used in subsequent sales and production links. In addition, the test efficiency of DFN37.9x23.8 type DFN devices will be relatively low and the test cost will be high. Utility Model Content

The connecting platforms 11 are rotatably connected to the base 4. The connecting platforms 11 can ensure the convenient rotation of the gland 3 relative to the base 4, so as to realize the convenient opening and closing of the gland 3 according to actual test needs. A through hole 2 is opened in the middle of the gland 3, and the through hole 2 is connected to the accommodating cavity 7. The through hole 2 can facilitate the heat dissipation of the DFN device body 6 during testing.
