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:
Both Flex and Rigid-Flex PCB require custom quotes. To get started, please send us your gerber file, along with your desired quantity and lead times as well as any additional requirements you have. Need assembly services with your flex/rigid-flex order? We can do that too! Contact our knowledgable support staff to see how we can help you with your next PCB project.
