Technical Principles of PCB Laser Cutting Machines

From a technical perspective, PCB laser cutting machines primarily rely on a high-energy-density laser beam generated by a laser generator. This beam is precisely focused onto the surface of the PCB material through a focusing system, causing the material to melt or vaporize instantaneously, thus achieving the cutting purpose. Depending on the laser source, PCB laser cutting machines can be categorized into several types, including CO2 laser cutting machines, fiber laser cutting machines, and ultraviolet laser cutting machines. Among these, fiber laser cutting machines are widely used in the PCB processing field due to their high cutting speed, high precision, and low maintenance costs.
