Circuit board (PCB), as the "mother of electronic products", is basically the upstream of all electronic consumer goods, whether it is mobile phones, computers, tablets, monitors, etc., all use circuit boards, which are the key components in today's electronic component industry. One, it has a wide range of applications.

China is the largest PCB producer in the world, but the company scale is smaller than that of traditional powers such as South Korea and Japan, and the industry concentration is low. Looking forward to the future of China's PCB industry, the concentration of the industry will increase, and large-scale mass production and manufacturing has become an inevitable trend. It also seems to be crucial to the standardization and mass management of PCB completion.

With the continuous development of smart phone technology and wearable electronic technology, intelligence, thinness, and miniaturization have become popular, and manufacturers have become more and more stringent on the production and manufacturing regulations of PCB circuit boards in such electronic products. In order to complete the quality information control of commodities as soon as possible, information traceability systems such as marking characters, barcodes, and QR codes on the PCB board came into being.

The traditional screen printing process uses the prepared graphic screen, and uses external pressure to make the character ink pass through a part of the screen of the screen, and miss printing on the surface of the circuit board. Part of the mesh on the screen will be blocked, and the ink will not pass through, only blank pages will be generated on the surface of the circuit board, and the missing ink will produce text, logos, pattern designs, etc. This kind of production and processing method is relatively cheap, and the production and processing speed is relatively fast, but the actual effect of the marking is not smooth, the marking is easy to fall off, the PCB board with small format cannot be marked, and the chemical raw material has certain toxicity.

Laser marking uses a high-energy-density laser to partially direct the PCB board to vaporize or discolor the surface raw materials, thereby leaving a permanent mark. This kind of non-contact production and processing can mark a very clear QR code on a very small format, ensuring high precision and high quality. In addition, the laser marking is not easy to be damaged due to high and low temperature tests, pH changes and external friction, and it is not assisted by compounds, which has no negative effect on the safety of the staff of the Laser Marking Machine manufacturer and the natural environment.

PCB laser marking machine is a special model for marking barcodes, two-dimensional codes, characters, graphics and other information on printed circuit boards. Using the PCB laser marking machine to complete the information marking on the circuit board can record the production and manufacturing information of the circuit board, complete the management and control of product information in the production process, and make the entire life cycle of electronic products traceable. In addition, the use of excellent laser marking technology can improve production efficiency, control costs, and reduce environmental pollution. It is an ideal choice for PCB marking.

With the re-expansion of China's 3C industry, the prevalence of electronic device terminal equipment such as smart phones, tablets, and green base stations, and the focus of the electronic device industry chain such as the global mobile telecommunications sales market has once again been sold from the sales market of Western countries to Asia. The market deviation will have a strong pulling effect on China's PCB. In this process, laser marking technology will also accompany the PCB industry all the way forward.
