[0002] A flexible circuit board is a substrate used to connect electronic components. Its main features are soft materials and bendability. Compared with traditional rigid circuit boards, it is more flexible and adaptable. Flexible circuit boards are usually composed of a flexible substrate (such as polyester film or polyimide film) and a conductive copper foil, where the conductive copper foil serves as the conductor of the circuit. Due to its softness and thinness, flexible circuit boards are widely used in electronic products that need to be bent, folded, or have small space constraints, such as smartphones, tablets, wearable devices, etc.
