pcb laser marking - the best process for circuit board marking

PCB circuit board is one of the most important components in electronic component products, and the production requirements of PCB circuit board are also very strict, and errors are not allowed. The laser marking machine has high precision 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 breaking through itself and improving, and 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 procedure is cumbersome, and the operator needs to be replaced in time to ensure the production efficiency, which increases the labor cost. In addition, ink is a chemical material. If it is used together for a long time, it is harmful to the human body and also causes great pollution to the environment. Now many industrial parks in many areas do not allow the use of silk screen printing.

The 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 little thermal impact, which ensures 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.

As an important component and line connection carrier in the 3C industry, with the development of intelligence in the electronic industry, the PCB circuit board has more and more electronic components, and the requirements for precision machining are also getting higher and higher. In the PCB industry, the laser marking machine is specially used to mark traceable information such as barcodes, two-dimensional codes, characters, graphics, etc. The need for process improvement.


The laser marking machine has high marking accuracy, fast speed and stable performance, and only needs to be controlled by a computer. It is easy to operate, and can print various complex patterns, text, two-dimensional codes, etc., which meets the high-quality marking requirements of the existing PCB industry. . It can make up for the lack 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 have higher absorption of UV laser than infrared laser, and UV photons are marked by "cold processing" that directly destroys the chemical bonds on the surface of the material. Infrared carbon dioxide is marked by "thermal processing" by evaporating the surface material at high temperature, the surface carbonization degree of the material is extremely low, and the marking edge is smoother and finer.


It can be seen that the effect of using a laser marking machine for PCB circuit boards is significantly better than that of traditional marking methods. The non-contact processing can ensure that there are no accidents in the processing process, the effect is smooth and fine, and the graphic text of the laser marking machine is used. The effect is more intuitive.
