There are four basic types of flexible circuits(FPC) are available. These four types of flexible circuits can be used in different combinations to solve most every interconnection design problem.

1. The simplest flexible circuit is single-sided FPC. They provide maximum flexibility for dynamic applications and can withstand hundreds of millions of flex cycles. These simple circuits are also the most easily adaptable to SMT, TAB, and other developments in circuit technology.

2. Double-sided FPC consists of double-sided copper clad material with top and bottom cover films. The ability to interconnect between sides using through-hole plating helps double-sided circuits carry complex designs, and still maintain flexibility.

3. Multilayer FPC are ideal for complex, highly populated design requirements. Large numbers of conductors can be designed into a small package. Maybe flexibility will be somewhat limited by the number of layers in the design. Multilayer circuits are also the ideal problem-solving technology when confronted with design challenges like unavoidable crossovers, specific impedance requirements, elimination of crosstalk in sensitive circuits, additional shielding or ground planes, and high component density.

4. Rigid-Flex circuits are circuits combination of Rigid circuit and Flex circuits. So it have both the advantage of each other and it’s newest types used in various applications.
