The PrintedCircuitBoard, a PrintedCircuitBoard, mainly consists of two types of materials, namely insulating base material and conductor, playing a supporting and interconnecting role in electronic equipment. The main advantage of using circuit boards is to greatly reduce wiring and assembly errors, improve the level of automation and production labor.

As an indispensable component of electronic products, PCB demand presented a steady growth trend. Data showed that the global PCB industry grew rapidly from 20009 to 2017 with an average annual growth rate of 4.55%. In 2017, the output value of global PCB was 58.8 billion usd, with a year-on-year growth rate of 8.60%.
