[0022] In this embodiment, the placement plate 5 of the device is divided into two structures. One side is provided with a network plate 6, which can directly place the circuit board horizontally, while the other side is provided with multiple clamping structures. The clamping structures can clamp and fix the circuit board through the movable clamping block 11 and the fixed clamping block 7, so that the circuit board maintains its numerical state during the test, thereby simulating the real situation during actual use and improving the accuracy of the test structure.

[0023] When using the clamping structure to fix the circuit board, first push the movable clamping block 11 towards the fixing base 8 until the distance between the movable clamping block 11 and the fixed clamping block 7 is greater than the thickness of the circuit board. At this time, place the circuit board between the two and then slowly move the movable clamping block 11 closer to the fixed clamping block 7 until the two clamp and fix the circuit board. The stability of the clamping structure can be ensured by the spring 10. In this structure, the horizontal slide bar 9 plays a guiding role to ensure that there is no positional displacement between the movable clamping block 11 and the fixed clamping block 7.

[0030] In this embodiment, the door 17 is used to seal the test chamber 2, ensuring that the internal environment is not disturbed by the outside world, and the staff can observe the status of the circuit board being tested inside the device through the observation glass plate 18.

[0031] Furthermore, the lower part of the front surface of the device frame 1 extends forward to form a control cabinet 15, on which a control structure is provided.

One side is provided with a network plate, which can directly place the circuit board horizontally, while the other side is provided with multiple clamping structures. The clamping structures can clamp and fix the circuit board through the movable clamping block 11 and the fixed clamping block 7, so that the circuit board maintains its numerical state during the test, thereby simulating the real situation during actual use and improving the accuracy of the test structure. When using the clamping structure to fix the circuit board, first push the movable clamping block 11 towards the fixed base 8 until the distance between the movable clamping block 11 and the fixed clamping block 7 is greater than the thickness of the circuit board. At this time, place the circuit board between the two, and then slowly move the movable clamping block 11 closer to the fixed clamping block 7 until the two clamp and fix the circuit board. The stability of the clamping structure can be ensured by the spring 10. The horizontal slide bar 9 in this structure plays a guiding role to ensure that there is no positional displacement between the movable clamping block 11 and the fixed clamping block 7.
