Aug 23 , 2021The QR code is a household name nowadays. In daily life, people use it to pay and add information. In the field of enterprise manufacturing, the QR code is also a symbol of information transmission. In the PCB circuit board industry, it can include The most important thing about the company's information and product details is that the QR code can play a role in product quality traceability and product source traceability, and can effectively control product materials, reject defective products, and product replenishment.
UV laser marking machine is no stranger to the field of PCB circuit board processing. With the rise of 3C electronic products, the demand for PCB has also greatly increased. In this large-scale and large-demand environment, UV laser marking The machine turned out to solve the problems of cost control, quality supervision, efficiency and speed of large-scale PCB processing for enterprises in one fell swoop. Compared with the traditional inkjet method, environmental protection is a challenge. Inkjet marking can be removed by chemical methods, and the labeling method can be removed by alcohol or heating. These two methods are easy to be tampered with and easy to be caught by criminals. Its vulnerabilities are exploited. The advantage of the QR code engraved by the UV laser marking machine is that it has no chemical consumables, environmental protection, and long-term marking. These two-dimensional codes cannot be altered, which effectively assists the traceability and anti-counterfeiting of PCB circuit boards, and plays a role in supervision. Highly automated processing will not delay work efficiency due to quality control issues.

Why is it a UV laser marking machine? Because the laser heads used in other laser marking machines are prone to high temperatures, it is easy to cause burnt problems on thin circuit boards such as PCBs, which can damage the circuit boards. UV laser marking machines use cold-processed light sources. In the process of marking the two-dimensional code, high temperature will not be generated, and effective marking work will be formed through the low temperature path. Secondly, the UV laser marking machine uses a 355nm laser head. Its focused spot is relatively small compared to other laser marking machines. That is to say, the essence of its spot is concentrated. For thin components such as PCB circuit boards, it can be For ultra-precision processing, even small areas can be clearly marked.
The current UV laser marking machine can be fully automated processing and processing, combined with the assembly line manufacturing and processing of PCB circuit boards, to form an automated industrial line, which is why the majority of circuit board processors have chosen UV laser marking machines.
