PCB (Printed Circuit Board) is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
Printed circuit board is the basis of electronic information products, so the application field of printed circuit board involves almost all electronic products, including communication and related equipment, computer and related equipment, electronic consumer goods, automotive electronics, aerospace electronics and other industries. Driven by the development trend of information and digitalization, PCB industry has broad market space and good development prospects.
In recent decades, the rapid development of integrated circuit technology and electronic information products has also led to the continuous progress of printed circuit board technology. Printed circuit board has gradually developed from single side to double side, multi-layer and flexible. As the new generation of electronic products need printed circuit board with higher density and more stable performance, high density and high performance will be the direction of printed circuit board technology development in the future. With the development of PCB towards refinement, the application of laser in PCB industry is increasing.
In the production process of circuit boards, barcode traceability is an indispensable link. For product production management and control of defective products, manufacturers will use bar codes, text and other information to mark the products. At this stage, ink label paper is generally used in the industry to stick to products, but this method has many problems: large amount of consumables, high pollution, high labor costs, and easy removal of marks. In response to this situation, it has become an industry trend for laser marking barcodes to replace label paper.
