Rigid flex circuits combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control. Designs are rigid where extra support is needed and flexible around corners and areas requiring extra space.  


While the design options are endless when combining rigid boards with flexible circuits, we have provided you with rigid flex combinations that are most commonly utilized.

What is a Rigid Flex PCB?

Rigid Flex circuit boards are composed of a combination of rigid and flexible printed circuit boards that are connected to one another by lamination. so most of the rigid flex pcb are made of multiple layers of flexible circuit substrates attached to one or more layer rigid boards internally or externally, depending upon your design for the specified application.


At present rigid flex pcb is applied in more and more application, as it can offers optimum solutions for limited installation space conditions. and also rigid flex pcb provides the possibility of secure and high electrical connection performance  of the device components with the assurance of contact stability, as well as a reduction in plug and connector components.


Rigid flex circuits have been used in the military and aerospace industries for more than 20 years. In most rigid flex circuit boards, the circuitry consists of multiple flexible circuit inner layers selectively attached together using an epoxy pre-preg bonding film, similar to a multilayer flexible circuit. However, a multilayer rigid flex circuit incorporates a board externally, internally or both as needed to accomplish the design.
