This arrangement allows the etching solution to enter the etching tank 3 from the inlet pipe 25. The etching solution then passes through the filter screen 7 and enters the L-shaped cavity 4. At this point, the second screw 10... Motor 22 drives the second screw 20 to rotate, which in turn drives the second moving block 21 to move. The movement of the second moving block 21 in turn drives the moving plate 18 to move, thus adjusting the spacing between the slots 19. At this time, the HDI board can be placed inside the slot 19 and clamped and fixed. Then, the first motor 17 drives the first screw 13 to rotate, which in turn drives the first moving block 15 to move, thus moving the ring plate 16. At this time, the liquid pump 8 can draw liquid and spray it onto the surface of the HDI board from the nozzle 12.
[0024] like Figure 3 As shown, support legs 2 are fixedly connected to the bottom of the body 1 and near the four corners. The support legs 2 are trapezoidal in shape. Through the above arrangement, the support legs 2 can support the bottom of the body 1.

[0028] like Figure 4 As shown, one end of the second screw 20 is rotatably connected to the inner wall of one end of the ring plate 16 and its bearing. A second motor 22 is embedded and fixedly connected to one side of the inner wall of the ring plate 16. The output end of the second motor 22 is fixedly connected to one end of the second screw 20. With the above arrangement, the second motor 22 can drive the second screw 20 to rotate.
[0029] like Figure 4 As shown, the bottom of the second moving block 21 and near both ends are fixedly connected to limit blocks 24. The center of each limit block 24 is slidably connected to a first limit rod 23. Both ends of the first limit rod 23 are fixedly connected to the ring plate 16. Through the above arrangement, the moving plate 18 can be limited.
[0030] like Figure 4 As shown, an inlet pipe 25 and an outlet pipe 26 are connected through and fixed to one side wall of the etching tank 3. Through the above arrangement, the effects of liquid inlet and outlet can be achieved.
[0031] The device is used and operates as follows: The etching solution enters the etching tank 3 through the inlet pipe 25. The etching solution then passes through the filter screen 7 and enters the L-shaped cavity 4. The second motor 22 drives the second screw 20 to rotate, which in turn moves the second moving block 21. The movement of the second moving block 21 moves the moving plate 18, allowing the spacing between the slots 19 to be adjusted. The HDI board can then be placed into the slot 19 and clamped and fixed. The first motor 17 drives the first screw 13 to rotate, which in turn moves the first moving block 15, which in turn moves the ring plate 16. The liquid pump 8 draws liquid and sprays it from the nozzle 12 onto the surface of the HDI board for etching.
