The basic principle of PCB laser engraving is very simple. The laser pulse acting on the material melts the material and creates a molten pool. After a certain amount of heat is generated, the surface of the material is vaporized, causing recoil working pressure on the melt, causing the melt to spray out. This is the key system for laser engraving to remove the material. laser cutter air filter.

You may have some misunderstandings about laser engraving. For example, you think that the higher the pulse kinetic energy, the larger the material removed; the higher the maximum output power and the smaller the duty cycle, the better the quality of laser engraving. In fact, the whole process of laser engraving is extremely complicated. At this stage, there is no solid processing plan to ensure the quality of engraving. Because the engraving quality and the material sludge load are mutually constrained, no matter from which level, customers need to improve the selection of pulse characteristics, optical components and main parameters of the processing/scanner to ensure processing quality and high processing efficiency.

In addition, if you only need to engrave wireframes and simple text, you can use laser vibration processing. This kind of technology is especially suitable for vehicle identification code (VIN) marking. The engraved vehicle identification code is still visible even after spraying and cannot be worn off, so it is safer. In addition, thanks to the powerful function of the laser system software, it is optional. Simply change the main parameters of the laser, such as reducing the duty cycle and increasing the repetitive working frequency, which can effectively eliminate the metal formed in the whole process of laser engraving.
