Flexible printed circuit boards are used to make interconnections in systems that have no room for rigid PC boards. Flex circuits are bendable and lightweight and are used in applications where the circuit is bent or flexed in two or more planes in the assembly or installation process.
Rigid-flex circuits are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure.The layers of a rigid flex are also normally electrically interconnected by means of plated through holes. Rigid-flex boards are normally multilayer structures.
A single sided flexible circuit construction with a polyimide cover film laminated to copper allowing access from one side only. Application of sigle sided flex circuits: Optical pick-up for a/v & computer ( or cdp & dvdp) Camera Capstan motor for camcoder & vcr Vibration motor for mobile phone Stepping motor.

General specification for Flexible PCB Because of the advantages, such as: cost, space, and weight savings, flexible and Rigid-Flex-circuit board shave for some projects, they are used ever more frequently. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Multi FCB can produce your flexible circuit boards with the highest quality, either as prototypes or in series. For additional technical questions about flexible circuit boards, please contact us.
