Rigid-Flex circuit boards are composed of a combination of rigid and flexible circuit boards that are permanently connected to one another.
The proper application of Rigid-Flex circuit boards offers optimum solutions for difficult, limited space conditions. This technology offers the possibility of a secure connection of device components with the assurance of polarity and contact stability, as well as a reduction in plug and connector components.
Additional advantages of pcb bare board are dynamic and mechanical stability, the resulting 3-dimensional freedom of design, simplified installation, space savings, and maintenance of uniform electrical characteristics.
Use of Rigid-Flex circuit boards can reduce the total cost of the final product.
Rigid-Flex circuit boards give you unlimited freedom of packaging geometry while retaining the precision density and repeatability of printed circuits.
As a high reliability replacement for wire and wire harness assemblies, flex circuits provide a significant cost savings with no reduction in performance.
This Medical Rigid-Flex FPC illustrates how designers use flex to reduce board thickness as well as package size and weight, and incorporate connectors into the bare board design.
