At present, laser marking machine is widely used in a variety of widely used in electrical appliances, communications, precision instruments, electronic components, electrical products, integrated circuits, hardware tools products, auto parts, plastic products, craft decorations and many other fields, is the 3C industry ultra-fine processing high-end market darling. As a familiar face in people's life, PCB benefits from laser precision processing, and various creative PCB models emerge in endlessly.

So many "playing" methods show the wide application of PCB in our life. In electronic products, PCB board is an indispensable member, which is equivalent to the human body and blood. Therefore, PCB quality control becomes more important. In order to control the whole PCB production process, manufacturers will choose to use laser marking technology and print two-dimensional code on each piece of product, so that each piece of product has a unique identity code. Through CCD automatic code scanning identification, product production cycle paperless, system anti-freeze, real-time data recording, quality traceability and other functions, to ensure the one-to-one correspondence of human, machine, material, method (process and control tools), ring and other elements.With the trend of thinner and thinner PCB, the scope of printing TWO-DIMENSIONAL code is becoming smaller and smaller, and the specific area usually requires a two-dimensional code below 5x5mm. And in some special purposes, equipped with high-end barcode gun reading, laser marking technology can print 1.5x1.5mm or even 0.8x0.8mm two-dimensional code. Green laser marking machine special fine processing has also come into use.
