As the "mother of electronic products", PCB has a wide range of applications. With the development of intelligence in the electronics industry, PCBs have more and more layers, made smaller and thinner, and contain more and more electronic components, and there are higher requirements for processing precision. Because of its unique advantages, laser technology is increasingly used in PCB processing.

PCB is one of the important components of the electronics industry. The output value of the industry accounts for about a quarter of the total output value of electronic components. It accounts for the largest proportion in the various electronic component industries, and the flexible PCB board (ie FPC) is the most growing in the PCB industry. One of the fast sub-sectors. The advent of the 5G era also puts forward higher requirements for the R&D, production and management capabilities of the majority of PCB companies. Companies must provide more cost-effective products to the market at a faster speed. Improving the efficiency of product management traceability has also become a key part of it. 

In this way, as one of the industrial laser equipment, the laser marking machine has played an important role in the development of the PCB industry.

The laser marking machine, due to the combination of laser marking technology and computer, uses the current computer software control system, not only in metal Two-dimensional codes are marked on non-metallic materials, and various characters, product numbers, barcodes, serial numbers, production dates, patterns, logos and some special signs can also be customized and personalized.

In order to better control the quality of products, it is necessary to record relevant production information to facilitate the full traceability and quality control of electronic products. The internal structure of the product-PCB marking information needs to be clear, and at the same time increase productivity and reduce costs in production. Reduce pollution and adapt to the development of multi-variety, small-batch production. In order to better realize the management and control of many pcb boards in the product production process, marking information on pcb boards, such as production batches, characters, bar codes and other information, has become the development trend of the industry. Laser marking processing, as a high-tech means of marking processing, has advantages that traditional processing methods can’t match. Unlike traditional processing methods, laser processing uses high-energy-density lasers to locally irradiate the workpiece to vaporize or vaporize the surface material. A marking method in which a chemical reaction that changes color, leaving a permanent mark.

Laser marking can produce a variety of characters, symbols and patterns, etc., and the size of the characters can range from millimeters to micrometers. This is an effective anti-counterfeiting product. For the current PCB industry, it is undoubtedly one of the best processing solutions, whether it is fine processing, processing efficiency, and processing effects, it fully meets the needs of current PCB marking processing.

PCB circuit board laser marking machine is a special model specially used for marking bar codes, two-dimensional codes, characters, graphics and other information on printed circuit boards. It can automatically complete loading, board removal, positioning, marking, Work station switching, blanking and other processes can be combined with the SMT production line to operate online, and can also be combined with an automatic loading and unloading machine to form an offline workstation. It is the preferred model for circuit board marking.

With the continuous expansion of China’s 3C industry, the rise of electronic terminals such as smart phones, tablet computers, and green base stations, as well as the global mobile telecom market, the focus of the electronics industry is continuing to shift from the Western market to the Asian market, which will affect China’s PCB Produce a powerful pulling effect, in this process laser technology will also accompany the PCB industry all the way forward.
