Flexible circuit board is a type of circuit board composed of insulating film and conductive lines, which has high flexibility and foldability. It can freely bend, fold, and roll in three-dimensional space, adapt to various complex shapes and narrow spaces, and is widely used in fields such as electronic devices, communication devices, automotive electronics, medical equipment, etc. Advantages of flexible circuit boards 1. High flexibility and toughness Flexible circuit boards can be freely bent, folded, and wound, and can adapt to various complex shapes and narrow spaces, which makes them highly flexible in design and application. 2. Lightweight and portable Compared to traditional rigid circuit boards, flexible circuit boards are thinner, lighter in weight, and easier to carry and install, which helps to achieve miniaturization and lightweighting of devices. 3. High reliability -The flexible circuit board adopts advanced manufacturing technology and high-quality materials, with good electrical and mechanical properties, and can work stably under harsh environmental conditions, improving the reliability and service life of the product. 4. Good heat dissipation performance -The material of flexible circuit board has good thermal conductivity, which can effectively dissipate heat and avoid equipment failure caused by overheating. 5 Cost effectiveness Although the initial investment of flexible circuit boards is relatively high, their cost in the production process is low, and they can improve production efficiency, reduce production costs, and have good cost-effectiveness.
