FPC Stiffener is mainly to enhance the mechanical strength and stability of the circuit boards, as well as to improve the reliability and service life of the circuit boards.

Because FPC flexible circuit boards are thin and bendable, their mechanical strength and stability may not meet the requirements in some application scenarios, and reinforcement is required.

Steel sheet reinforcement can increase the strength and stability of flexible circuit boards, and steel sheets can also form the required circuit patterns through etching processes.
