Flexible circuit boards have become a key factor in foldable smartphones. Ordinary circuit boards use electronic glass as the substrate and cover plate, which are rigid; And flexible circuit boards are made of special materials such as polyimide, which can adapt to screen bending. Folding screen phones use flexible circuit boards, which can achieve screen folding and unfolding, reduce body weight and thickness, and have high durability and reliability, able to withstand millions of bends. In addition, flexible circuit boards can improve the flexibility and innovation of mobile phone design, enhance overall performance and user experience, reduce production costs and environmental impact.
