Abstract

The invention provides a chip module test fixture and a chip module test system. The chip module test fixture comprises a turntable mounting plate; the first PCBA is fixed on the rotary table mounting plate, a plurality of accommodating spaces which are mutually spaced are arranged in the first PCBA, and each accommodating space penetrates through the first PCBA; each second PCBA is located in the corresponding containing space in the first PCBA and fixed to the rotary table mounting plate, and the first PCBA is connected with the second PCBAs; each socket is arranged on the corresponding second PCBA, the sockets are used for bearing a chip module to be tested, and the chip module to be tested is connected with the corresponding second PCBA through the sockets. Compared with the prior art, the jig testing PCBA adopts a split type design, so that the space utilization rate of a rotary table can be improved, and the number of cables for testing can be reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of chip testing, in particular to a chip module testing fixture and a testing system. 【Background technique】 [0002] The IMU / RTK chip modules used in vehicles usually need to perform angular velocity calibration and testing on the turntable equipment. Among them, the full name of IMU is Inertial Measurement Unit, which is inertial measurement unit; the full name of RTK is Real-timekinematic, which is carrier phase difference technology. . [0003] When the existing IMU / RTK chip module is used for small batch turntable test: [0004] 1. Each chip module has interfaces such as power supply, USB (Universal Serial Bus), RF (Radio Frequency, radio frequency), etc. There are many cables during testing. With the increase in the number of product tests, the lines will become more complex and messy, causing hidden dangers; [0005] 2. The space of the turntable equipment is limited. During the test, the space u...
