The QR code can carry a large amount of information, which is the basis for the traceability of product information, but this means that each product can have its own unique QR code. With the continuous advancement of science and technology, the continuous improvement of people’s living standards, portable thinning has become the mainstream, and consumers’ requirements for product quality will become higher and higher, so as a manufacturer, the quality control of internal PCB circuit boards is also becoming more and more important. The stricter, the UV laser marking machine can be applied to the two-dimensional code marking of the circuit board, which helps the traceability and secondary purchase of the products of various enterprises.
Compared with the inkjet method, the 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. 12mm 31-digit QR code laser marking, more importantly, has a long service life, which can reduce a lot of production costs for enterprises in continuous work. With the advantage of fast processing efficiency, a QR code can be processed within 1 second. can be completed. Compared with the processing of ink, the laser marking machine is also more environmentally friendly for the production workshop, because it will not generate waste gas and waste water due to the ink, thus avoiding pollution.
Comparing the advantages of comprehensive laser marking technology with the advantages and disadvantages of inkjet method, it can be seen that when the new generation of circuit board QR code marking and UV laser marking machine technology are combined, it becomes a perfect partner for fine processing and increasing The anti-counterfeiting function has created a broad application space. The UV laser marking machine helps the circuit board industry to complete the perfect quality control, and the vast PCB board market provides a broad development space for the laser marking machine industry.
