Rigid Flex PCB Manufacturer

Rigid Flex PCB Manufacturing and Assembly in the USA

Blind Buried Circuits offers high-quality rigid-flex printed circuit board manufacturing and assembly for all your product development needs. As a leading manufacturer and assembler of rigid-flex PCBs in the USA, we take pride in providing our customers with high-quality printed circuit boards that meet their custom PCB requirements.

What are Rigid-Flex PCBs?

The Rigid-Flex PCBs combine rigid and flex materials, which helps customized products fit specific needs. It can be laminated in different thicknesses and accommodate many layers. The designers ensure that the traces are designed in a way that helps multiple bends and folds fit into the tight spaces. Rigid-Flex PCBs are mainly used in medical devices, aerospace systems, and military applications. They are mainly used in products with limited space and require high reliability and performance.
