Automation control is the most fundamental application in modern manufacturing factories, and FPC flexible circuit boards are indispensable components in automation control equipment. Widely used in mechanical twisted connections, flexible components, signal transmission, and control. China's industrial control started relatively late and belongs to the development process of import substitution. But with the acceleration of industrial automation upgrading in China and the industrial upgrading of downstream intelligent manufacturing equipment, more and more automated production lines are developing, and the market share is constantly increasing. There is still a huge market and development demand for domestic industrial control in the future, which is expected to drive a significant increase in FPC demand.
