Flex and Rigid-Flex Circuits

Flex PCBs, also known as flexible printed circuits or flexible electronics, provide greater options for designers and engineers when assembling electronic circuits.

They are constructed from flexible, high-performance plastic material, usually polyimide, which enables the board to bend or "flex" during use. This flexibility opens them up to use in a wide range of applications.

Rigid-flex are a type of high-adaptability printed circuit boards that use both flexible and rigid-board construction in an application. Though they offer greater spatial effiency, rigid-flex PCB require different design rules and can be more challenging than designing a rigid board. PCB International is experienced with helping many of our customers bring their complex rigid-flex design to market. All of our products come with full engineering DFM support.

Here are the most common types of flex circuit construction:
