Fiber Laser Marking PCB

With the continuous advancement of science and technology, fiber laser marking technology is increasingly used in various industries. With its high precision, high speed and high reliability, this technology has become one of the important means of modern marking and engraving. Especially in the field of electronic manufacturing, the application of fiber laser marking technology on PCB has greatly improved production efficiency and product quality.

Overview of fiber laser marking technology

Fiber laser marking is a technology that uses fiber lasers to generate high-energy laser beams to quickly and accurately mark material surfaces. This technology achieves deep marking of different materials (such as metals, plastics) by focusing laser energy into a small area. Compared with traditional marking methods (such as thermal printing, mechanical engraving), fiber laser marking has higher speed and longer service life, while having less impact on the environment. In addition, laser-marked products also have significant advantages in wear resistance and corrosion resistance.

Importance and applications of PCB

PCB is the core component of electronic equipment, responsible for the functions of electrical connection and signal transmission. In modern electronic products, the design, manufacturing and surface treatment of PCB directly affect the performance and reliability of the product. With the popularity of electronic products such as smartphones, computers, home appliances, and automobiles, the demand for PCBs continues to rise, driving the progress and innovation of its manufacturing technology.

In the PCB production process, marking is not only an important link for identification and traceability, but also a key step to ensure product quality and compliance. Through laser marking technology, product information, barcodes, QR codes, etc. can be accurately burned on the PCB surface, which is helpful for subsequent electronic component management and after-sales service. Therefore, fiber laser marking technology plays an increasingly important role in PCB manufacturing, providing strong support for the rapid development of the electronics industry.

The working principle of laser marking is mainly to focus a high-energy laser beam on the surface of the material and use the heat energy of the laser to cause physical and chemical changes in the material.

Laser emission: The laser generates a high-intensity laser beam, which is transmitted to the marking head through an optical fiber or a reflector.

Focusing: The laser beam is focused to a very small point through a lens, forming a strong energy density.

Material action: When the laser beam is irradiated on the surface of the material, the material is heated to a state of evaporation or melting, forming a mark, text or pattern.

Cooling and curing: After the marking is completed, the material gradually cools down to form a clear and wear-resistant mark.

By adjusting parameters such as the laser power, frequency and marking speed, laser marking can achieve markings of different depths and effects, and is suitable for a variety of materials such as metals, plastics, and wood.

1. High precision and high resolution: Laser marking can achieve extremely high precision in a small area and is suitable for high-density and high-complexity PCB layouts.

2. Non-contact marking: Laser marking is a non-contact processing method that does not cause physical damage to the PCB material and can maintain the integrity and functionality of the product.

3. Durability and persistence: Laser marked marks have excellent wear resistance and corrosion resistance, are not easy to fade, and can remain clear for a long time in harsh environments.

4. Fast processing speed: Laser marking is usually faster than traditional marking methods, which can significantly improve the efficiency of the production line and meet the needs of mass production.

5. Environmental protection: There is no need to use chemicals or other harmful materials during the laser marking process. It is relatively environmentally friendly and meets the sustainable development requirements of modern manufacturing.

6. Flexibility: The laser marking system can be programmed as needed, can quickly adapt to different marking projects, and supports customized needs.

7. Good traceability: Through laser marking, manufacturers can clearly mark serial numbers, barcodes or QR codes on PCBs, which facilitates product traceability and quality management.

Laser marking technology not only improves the quality and efficiency of marking in PCB manufacturing, but also reduces the consumption of resources, which is in line with the needs and development trends of modern manufacturing. Click here to contact Suntop Laser now for more information.
