Analysis of the Advantages of Laser Marking in the PCB Industry

1. The Development Characteristics of Laser Marking Technology


Laser marking technology is a very advanced marking technology. It uses focused laser engraving technology to engrave the characters and patterns to be marked on the surface of the object. Compared with traditional printing technology, laser marking has the characteristics of good quality, high consistency, strong wear resistance, high efficiency, cost saving, safety and reliability, etc., so it is widely used in the PCB industry.


The emergence of laser marking technology has successfully solved a series of problems in traditional printing technology. It is characterized by high marking accuracy, fast speed and stable performance. And it only needs to be controlled by a computer. Its operation is simple, and it can print various complicated patterns, characters, two-dimensional codes and other content, which fully meets the high-quality marking requirements of the existing PCB industry.


2. Compared with Traditional Printing Technology, the Advantages of Laser Marking Technology:


(1) Good Quality and Strong Wear Resistance


PCB surface marking is clear and beautiful. It can mark all kinds of logo, pattern, two-dimensional code, text, and the pattern is directly carved on the material, so the wear resistance is more prominent.


(2) High Processing Accuracy


After the laser beam emitted by the laser is focused, the smallest spot diameter can reach 10um (UV laser), which is helpful in processing complex graphics and precision processing;


(3) High efficiency, Simple Operation and Lower Cost


The user only needs to set the parameters on the computer to mark directly, and the surface marking of the material can be completed in just a few to ten seconds.


(4) Non-Destructive Marking


Laser marking adopts non-contact processing. The laser head does not need to touch the surface of the material, so there is no need to consider the damage to the material;


(5) Wide Range of Use, Safety and Environmental Protection


All kinds of thin metal/non-metal materials can be marked;


(6) Stable Performance and Long Equipment Life


With the development of technology, the service life of lasers has been greatly increased, and the service life of equipment has been greatly lengthened.
