[0002] FPC is a printed circuit made of a flexible insulating substrate. It has many advantages that rigid printed circuit boards do not have, such as being able to be bent, wound, and folded freely, and being able to be arranged arbitrarily according to spatial layout requirements. The use of FPC can greatly reduce the size of electronic products, and is suitable for the development of electronic products towards high density, miniaturization, and high reliability. Therefore, FPC has been widely used in mobile communications, laptops, computer peripherals, digital cameras, and other fields.
