What factors are related to the cutting speed of PCB laser cutting machine?

As an important carrier of electronic components, circuit boards need to be divided into individual small pieces of finished products during the actual production process, which requires a laser cutting machine. Common cutting methods have been gradually eliminated due to low cutting quality and efficiency. Currently, the most commonly used cutting process is laser cutting. When laser cutting first emerged, the speed could not meet the processing needs. With the continuous improvement of the process and the upgrading of technology, it is now ideal in terms of cutting quality and efficiency.

First, let’s understand the processing principle of laser cutting machine. Laser cutting uses a high-energy beam to enter a galvanometer through a beam expander. The galvanometer drives the lens to deflect, and is introduced into a field lens to focus into a smaller spot that scans back and forth on the PCB surface, ablating layer by layer to form a cutting effect.

What factors are related to laser cutting speed? The first is the processing material. PCB circuit boards of different materials have different effects on the laser cutting speed. Paper substrate PCB, which is relatively easy to process, has higher processing efficiency, followed by FR4, fiberglass board, etc. Copper-clad laminate and aluminum substrate are more difficult to process. The second is the thickness of the processed material. The thinner the material, the easier it is to process. There is also the power of the laser. The higher the relative power, the higher the processing speed. Of course, it also depends on the type of laser. The mainstream lasers for cutting PCB processing on the market include ultraviolet lasers and green lasers. The processing effect of UV laser is relatively good, but the processing speed is low; the processing speed of green laser is fast, but the effect is not as good as UV.

From the above introduction by laser cutting machine manufacturer men-luck, we can know that there are many factors that affect laser processing speed. When cutting PCB boards of different thicknesses and materials, if you want to achieve higher cutting speed and cutting quality, you need to adjust the equipment. The specific configuration is subject to actual application cutting. For more PCB laser cutting machine cutting processes and frequently asked questions, please visit our official website.
