[0002] With the rapid development of the electronics industry, multilayer circuit boards have been widely used in the fields of communication equipment, computers and their peripherals, consumer electronics, etc. due to their advantages such as high integration and miniaturization. In order to achieve electrical connection between different layers, holes need to be drilled on the circuit board to form through holes or blind holes. Laser drilling technology has become an indispensable part of the modern manufacturing process of multilayer circuit boards due to its high precision, fast efficiency and little impact on materials.

[0003] However, there are some problems in the existing laser drilling devices, especially in dealing with the by-products generated. When using a laser to drill holes, a large amount of soot and harmful gases will inevitably be generated. If these substances cannot be effectively removed, it will not only affect the cleanliness of the working environment, pose health hazards to the operators, but also may contaminate the surface to be processed and reduce the product quality. In addition, the accumulated dust may also cause a decline in the performance of the laser or even damage the equipment.

[0004] In order to solve the above problems, we propose a laser drilling device for multilayer circuit boards, which can efficiently remove the soot and harmful gases generated during the laser drilling process, ensure the safety of the production process, and also improve the product quality.

[0023] When using this device, the staff places the multi-layer circuit board to be laser drilled on the upper side of the base 1 and limits it by the four limiting plates 5 in the front, back, left, and right directions. The adjustment mechanism can adjust the position of the limiting plate 5 according to the size of the multi-layer circuit board to adapt to multi-layer circuit boards of different sizes. After the multi-layer circuit board is placed, drilling processing is performed by the laser drilling machine 4.

On the upper side of the base 1, both the left and right parts are fixedly connected with a mounting plate 6. On the mutually distant sides of the left and right mounting plates 6, a suction hood 7 is communicated. The suction hood 7 is communicated with a suction pipe 8.
