The effect of using two-dimensional code uv laser marking laser on PCB circuit board

Compared with the inkjet method, the RFH PCB laser marking technology is more environmentally friendly and economical, the permanent mark will not be easily erased, the non-contact non-destructive marking will not damage the substrate, the processing accuracy is high, and small format can be achieved 0.12x0.12mm 31-digit QR code laser marking, long service life, more than hundreds of thousands of hours of continuous work, fast processing efficiency, a QR code can be completed within 1 second, the marking is exquisite, and there is no need to touch it by hand. Obvious touch, easy manual operation, fool-like processing.

Two-dimensional code laser marking machine fully reflects the advantages of marking technology in the PCB circuit board industry. The marked two-dimensional code has good quality, high efficiency, durable marking, high consistency, low cost, safety and reliability and is widely used. With the continuous development of smartphone technology and wearable electronic technology, intelligence, thinning and miniaturization have become the mainstream, and consumers will have higher and higher quality requirements for products. What is the effect of QR code laser marking machines in the processing field? how?

So how to realize the quality control of PCB, which requires the use of product quality traceability system. The commonly used method is to use laser marking technology to mark strings, one-dimensional codes, two-dimensional codes and other information on the PCB board, upload it to the database through camera recognition, automatically remove unqualified products, and realize the products of the entire internal process Quality traceability, from source supplier information to product outbound data tracking, tracking the whole process, maximize product quality, and effectively realize the control of product automation production.

With the development of thinning and miniaturization of electronic equipment, the size of PCB board is very small. In order to save space utilization, usually, the QR code marked on the PCB board is very small, such as 2x2mm size QR code , and contains more than 20 character information, this kind of high-density, small-format QR code marking can only be achieved by PCB laser marking machine technology.

Compared with the inkjet method, the RFH PCB laser marking technology is more environmentally friendly and economical, the permanent mark will not be easily erased, the non-contact non-destructive marking will not damage the substrate, the processing accuracy is high, and small format can be achieved 0.12x0.12mm 31-digit QR code laser marking, long service life, more than hundreds of thousands of hours of continuous work, fast processing efficiency, a QR code can be completed within 1 second, the marking is exquisite, and there is no need to touch it by hand. Obvious touch, easy manual operation, fool-like processing.

Comparing the advantages and disadvantages of the comprehensive laser marking technology with the advantages and disadvantages of the inkjet method, it can be seen that when the new generation of PCB QR code marking and laser technology are combined, they become partners. RFH laser marking machine helps the PCB board industry to complete better quality control, and the vast PCB board market provides a broad development space for the laser marking machine industry.
