Laser engraving is a very advanced engraving technology. Through the focused laser engraving technology, the characters and patterns to be marked are engraved on the surface of the object. Compared with traditional printing technology, the products engraved by laser engraving machine have the characteristics of good quality, high consistency, strong wear resistance, high efficiency, cost saving, safety and reliability, etc., and are widely used in the PCB industry.
With the rapid development of the IT industry, smart phones, wearable electronic products and other products are constantly developing in the direction of thinner, lighter and smaller. Consumers are increasingly demanding electronic products, and the production of PCB boards must also increase. In order to realize the quality control of the PCB board production process, it has become an industry development trend to trace characters, one-dimensional codes, two-dimensional codes and other information on the PCB board.
Due to problems such as poor wear resistance, low precision, poor aesthetics, and environmental pollution, traditional printing technology is increasingly unable to adapt to new market technical needs. Therefore, laser engraving has become a new trend in the PCB industry.
Unique Advantages of Laser Engraving Machine
The emergence of laser engraving technology has successfully solved a series of problems in traditional printing technology. It is characterized by high engraving precision, fast speed and stable performance. And it only needs one computer to control, easy to operate, and can print various complex patterns, characters, QR codes, etc., fully meeting the high-quality marking requirements of the existing PCB industry. Compared with traditional printing technology, laser engraving technology has many advantages:
- Good quality and strong wear resistance. The surface marking of the PCB board is clear and beautiful, and various LOGOs, patterns, QR codes, and text can be marked. The patterns are directly engraved on the material, and the wear resistance is more prominent;
- High processing precision. After the laser beam emitted by the laser is focused, the minimum spot diameter can reach 10um (ultraviolet laser), which is of great help in processing complex graphics and precision processing;
- High efficiency, simple operation and low cost. The user only needs to set the parameters on the computer to mark directly, and it only takes a few seconds to ten seconds to complete the marking on the surface of the material.
- Non-destructive marking. Laser marking adopts non-contact processing, the laser head does not need to touch the surface of the material, and there is no need to consider the damage to the material;
- Wide range of use, safe and environmentally friendly. Can mark various thin metal/non-metal materials;
- The equipment has stable performance and long service life. With the development of technology, the service life of lasers has been greatly improved, and the service life of equipment has also been greatly extended.
