FPC (Flexible Printed Circuit) is a flexible printed circuit board, while PCB (Printed Circuit Board) is a rigid printed circuit board. The main difference between the two lies in the substrate and application environment.

Substrate: FPC uses flexible substrates such as polyimide (PI) or polyester film (PET), while PCB typically uses rigid substrates such as FR-4 epoxy glass cloth.

Flexibility: FPC has high flexibility and bendability, suitable for applications that require frequent bending or three-dimensional spatial layout; However, PCBs are relatively hard and not suitable for frequent bending situations.

Application: FPC is widely used in fields such as mobile phones, tablets, and automotive electronics, especially in areas that require high-density integration and flexible wiring; PCB has applications in various electronic devices, especially in situations where bending is not required.

Cost: The production cost of FPC is relatively high because its manufacturing process is more complex; The cost of PCB is relatively low and the production process is mature.
