Abstract

The present invention relates to the radio frequency test technology field, especially to a method and a device of signal connection of a mainboard and a small board. The device comprises a radio frequency test device, and a mainboard and a small board arranged on the radio frequency test device. The main board is provided with a test bench, and the small board is provided with a radio frequency connection head; the test bench is configured to calibrate and test the indexes of radio-frequency signals; the radio frequency connection head is configured to connect the radio-frequency signals to a mobile phone antenna; and a radio-frequency connecting line is connected between the test bench and the radio frequency connection head. The method and device of signal connection of the mainboard and the small board are firm and stable in structure, small in occupied wiring area of the mainboard, low in cost and small in the radio-frequency signal insertion loss, etc.

Description

technical field [0001] The invention relates to the technical field of radio frequency testing, in particular to a method and a device for connecting signals of a main board and a small board. Background technique [0002] For the mobile phone with broken board design, the current design plan: 1. The signal enters the test socket. Under normal circumstances, the internal shrapnel of the test socket is connected to the left pin, and the signal enters the RF connector; 2. When the workshop is performing calibration tests, The shrapnel inside the test seat is lifted, and the signal enters the test instrument from the test line; 3. Under normal circumstances, when the calibration test is not in the workshop, the signal enters the RF connector, and then connects to the antenna with an RF cable. The current design will occupy the wiring area of ​​the motherboard, increase the cost, and increase the insertion loss of the radio frequency signal at the same time. [0003] For exampl...
