Is it true that the higher the power of a UV laser cutting machine, the better?

UV laser cutting machine is an important tool in the field of micro-precision laser processing. Commonly used languages are PCB circuit board cutting, ultra-thin metal cutting, film cutting, film material etching, etc. We all know that the higher the power of the UV laser cutting machine, the higher the efficiency. Is it true that the higher the power, the better?

Increasing the power can certainly improve the efficiency, but the effect may not necessarily achieve the effect of low power.

Take FPC circuit board as an example. The higher the power of FPC circuit board UV laser cutting, the higher the efficiency, which can increase the scanning speed of processing, reduce the working time of FPC and laser, and significantly reduce carbonization. This is why the market generally abandons the early 10W UV laser cutting machine and uses 15W. In this field, the higher the processing efficiency of the 18W UV laser cutting machine, the better the processing effect and efficiency.

However, the processing of conductive film materials is in the opposite direction. The higher the power, the greater the impact on thermal influence and beam quality, the damage to the substrate, and the inability to meet the requirements of ultra-fine line width.

According to the experience of Laisai Laser, the greater the power of the UV laser cutting machine, the processing effect and efficiency in some fields have been significantly improved, such as the processing in the field of FPC circuit boards, but in some fields, the effect of low power is better, such as the etching field of thin film materials. And as the power of the UV laser cutting machine increases, the price cost increases. Therefore, in the process of selecting a UV laser cutting machine, comprehensive considerations are required. Combined with various factors, it is impossible to choose from a single perspective. If you need to consider factors such as power, effect, efficiency, pulse energy, beam quality, pulse width, repetition frequency, etc., manufacturers need to guide each other to be ideal.
