[0002] With the continuous miniaturization and functionalization of electronic products, flexible printed circuits (FPCs) have been widely used in modern electronic products as key connection components. Flexible printed circuits are widely used in smart phones, tablets, wearable devices, automotive electronics and other fields due to their bendability, lightness and high-density integration. However, due to the complexity of material properties and production processes, flexible printed circuits are prone to quality problems such as dimensional deviation, appearance defects, and conductivity problems during the production process. These defects may cause functional failure or shorten the service life of the final product. Therefore, it is particularly important to perform high-precision inspection of flexible printed circuits.
