The pcb circuit board is one of the most important parts in electronic component products, and the production requirements of the PCB circuit board are also very strict, and no errors are allowed. The PCB laser marking machine has high accuracy and flexible operation, which can make up for some of the shortcomings of traditional processing. PCB laser marking has become an indispensable part of the industrial production process, and the application field is constantly making breakthroughs and improvements. It is the best process for circuit board marking.

The traditional silk screen printing process is rough, and the logo is easy to fade and fall off, causing inconvenience to users. Moreover, the silk screen processing procedures are cumbersome, requiring timely replacement by operators to ensure production efficiency and increase labor costs. In addition, ink is a kind of chemical material, which is harmful to the human body if it is kept together for a long time, and it also pollutes the environment. Nowadays, industrial parks in many areas do not allow silk screen printing.

PCB laser marking machine has no force on the surface of the material, no cutting force, no mechanical deformation, no corrosion on the surface of the material, and the advantages of little thermal influence, ensuring the original accuracy of the material. It can be used for marking electronic components such as integrated circuits, circuit boards, resistors, capacitors, crystal oscillators, diodes, and triodes.

PCB laser marking machine has high marking accuracy, fast speed, stable performance, and only needs to be controlled by a computer. The operation is simple. It can print various complex patterns, texts, two-dimensional codes and other content, which meets the high-quality marking requirements of the existing PCB industry . It can make up for the shortcomings of silk screen processing and gradually become the best processing tool for PCB laser marking! Among them, the UV laser marking machine suitable for PCB circuit boards has an output wavelength below 400nm. Most materials absorb UV lasers higher than infrared lasers, and UV photons directly destroy the chemical bonds on the surface of the material to mark by "cold processing", which is different from Infrared carbon dioxide is marked by "thermal processing" of high-temperature evaporation surface material. The carbonization degree of the surface of the material is extremely low, and the marking edge is smoother and finer.
