Flexible PCBs, made from flexible substrates such as polyimide (PI) or polyester (PET), are thin, bendable, resistant to high and low temperatures (-200°C to 400°C), and vibration-resistant, enabling three-dimensional wiring. With a dynamic flex lifespan exceeding one million cycles, they significantly save space and reduce device weight, making them widely used in foldable phones, wearable devices, medical devices, automotive electronics, and aerospace. Flexible PCBs support high-density interconnect designs, combining excellent signal transmission performance with electromagnetic shielding. They are key components for the miniaturization of smart devices and innovation in mobile electronics, and are particularly well-suited for precision applications requiring repeated bending or complex assembly.
