Unique advantages of laser marking
The emergence of laser marking technology has successfully solved a series of problems in traditional printing technology. It is characterized by high marking accuracy, fast speed and stable performance. Moreover, it only needs to be controlled by a computer, and the operation is simple, and it can print various complicated patterns, texts, two-dimensional codes and other content, which fully meets the high-quality marking requirements of the existing PCB industry.
1. Good quality and strong wear resistance. The marking on the surface of the PCB is clear and beautiful, and various LOGO, patterns, two-dimensional codes, and text can be marked, and the patterns are directly engraved on the material, which has more outstanding wear resistance.
2. High processing accuracy. After the laser beam emitted by the laser is focused, the smallest spot diameter can reach 10um (UV laser), which is of great help when processing complex graphics and precision processing.
3. High efficiency, simple operation and lower cost. The user only needs to set the parameters on the computer to mark directly, and the surface marking of the material can be completed in just a few to ten seconds.
4. Non-destructive marking. Laser marking uses non-contact processing, the laser head does not need to touch the surface of the material, so there is no need to consider the damage to the material.
5. Stable performance and long equipment life. With the development of technology, the service life of lasers has been greatly increased, and the service life of equipment has been greatly lengthened.
The use of laser marking QR code technology in the PCB industry can realize PCB production, process, and quality traceability, and realize automated and intelligent management requirements to meet the needs of lean production, quality control, and process improvement. Marking two-dimensional codes on the surface of PCBs is currently a common demand of mid- to high-end customers and has been widely used.
Application areas:
PCB inline QR code laser marking machines are mainly used for automatic engraving QR code on PCB surface (different model according to PCB's size ), available on white oil, green oil, black oil and other inks and copper surface . It can automatically engrave QR code of raw materials procurement, production process, batch, manufacturer, date , and destination for trace ability and management.
