[0002] The motherboard is the most important component inside a mobile phone. It integrates components such as PCB board, resistors, capacitors, inductors, interface devices, and integrated circuits. To ensure that the motherboard can be used normally after a series of processes, it is necessary to test the motherboard or repair faulty motherboards.

[0003] In the prior art, such as Chinese Publication No. CN219799521U, this utility model relates to the field of motherboard testing equipment technology, specifically to a mobile phone motherboard testing and repair platform; it includes a fixed plate, with slide rails arranged parallel to each other on the left and right sides of the fixed plate, a slider slidably connected to the slide rails, a sensor mounted on the fixed plate on the outer side of the slide rails, a material placement plate on the slider, a drive assembly mounted on the fixed plate on the right side of the material placement plate, a first clamping mechanism on the left and right sides of the material placement plate, a second clamping mechanism vertically mounted on the first clamping mechanism, a housing connected to the fixed plate on the second clamping mechanism, a testing mechanism of the same height as the material placement platform at the rear end of the slide rails, the testing mechanism being mounted at the rear end of the fixed plate, and an electrical control box and a cooling fan on the bottom plate of the fixed plate. This utility model eliminates the need for manual fixing of the motherboard, improves testing efficiency, and is simple in structure and easy to use.
