Specialized Laser Marking Machine for Circuit Boards

The Specialized Laser Marking Machine for Circuit Boards is a device that uses a laser beam to perform non-contact marking on the surface of a circuit board (PCB). Its main function is to mark barcodes, QR codes, serial numbers, LOGOs and other information on PCBs for product traceability, quality control and automated production identification.

1. Ultra-high marking accuracy
The laser marking machine for circuit boards uses a highly stable laser light source, which can achieve detailed marking with a minimum line width of 0.001 mm, and the repeat positioning accuracy can be controlled within ±0.015 mm. Such high-precision performance ensures that high-density markings, such as QR codes, serial numbers and micro characters, can be completed in a limited space, meeting the processing needs of precision electronic components and small PCB boards, and avoiding the subsequent identification and tracking affected by blurred markings.

2. Flexible power options
The equipment provides 3W, 5W, 10W, and 15W laser power options, and users can choose according to specific material types and process requirements. Different powers are suitable for circuit boards of different thicknesses or materials, such as FR4 fiberglass boards, ceramic substrates or copper clad boards, effectively balancing the marking effect and material loss, ensuring the marking quality and extending the service life of the laser.

3. Flexible working range
For PCB products of different sizes and layouts, the equipment supports a variety of working formats such as 70×70mm and 110×110mm, which is suitable for marking single small boards or panel structures. Users can customize the processing area according to specific production needs, improve the versatility and adaptability of the equipment, and facilitate flexible switching on a variety of production lines.

4. Efficient and reliable
The electrical system of the whole machine adopts a standard 220V/50Hz input power supply, which is convenient for rapid access in conventional industrial sites. The equipment has a stable structure and a smooth operation process, and can be seamlessly connected with automation equipment such as SMT placement machines and AOI inspection systems.

5. Permanent marking and high temperature resistance
The marking depth can reach ≤0.1mm (depending on the material), ensuring that the marking content has strong adhesion and recognition, and is not easy to fall off due to friction, cleaning or environmental changes. Even after high-temperature processes such as reflow soldering, the marked information can still remain clear to avoid information loss, providing a strong guarantee for subsequent product quality management and traceability.
