The advantages of two-dimensional code laser marking machine in PCB circuit board industry are reflected incisively and vividly. The marked two-dimensional code is widely used for its good quality, high efficiency, long-lasting marking, high consistency, low cost, safety and reliability. With the continuous development of smart phone technology and wearable electronic technology, intelligence, thinness and miniaturization have become the mainstream, and consumers will have higher and higher requirements for product quality. What is the effect of QR code laser marking machine in the processing field?
So how to realize the quality control of PCB requires the product quality traceability system. The usual means is to mark the string, one-dimensional code, two-dimensional code and other information on the PCB board through laser marking technology, upload it to the database through camera identification, automatically eliminate unqualified products, realize the product quality traceability of the whole internal process, and track the whole process from the source supplier information to the product delivery data, so as to maximize the product quality, And effectively realize the control of automatic production of products.
With the development of thinness and miniaturization of electronic equipment, the format of PCB board is very small. In order to save the utilization of space, generally, the two-dimensional code marked on PCB board is very small, such as 2x2mm two-dimensional code, and contains more than 20 character information. The marking of high-density and small-scale two-dimensional code can only be realized by PCB laser marking machine technology.
Compared with ink-jet, PCB laser marking technology is more environmentally friendly and economical. Persistent marks will not be easily erased. Non contact non-destructive marking will not hurt the substrate. It has high processing precision and can achieve 0.12x0.5 in small format 12mm 31 bit two-dimensional code laser marking has long service life, continuous working for more than hundreds of thousands of hours, fast processing efficiency, a two-dimensional code is completed within 1 second, the marking is exquisite, there is no obvious touch when touched by hand, simple manual operation and fool processing.
Comparing the advantages and disadvantages of laser marking technology with inkjet, we can see that when the new generation of PCB QR code marking is combined with laser technology, it becomes a perfect partner. PCB laser marking machine helps the PCB industry complete perfect quality control. The broad PCB market provides a broad development space for the laser marking machine industry.
