Rigid-Flexible Circuit Board Design Fabrication and Assembly Immersion Gold PCB
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 Rigid-Flex circuit boards 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.
A standardized manufacturing process following IPC guidelines guarantees a reliable and simultaneously an economical product, which is UL certified (UL94 / V-0); application of the UL logo is available at no extra cost.
Depending on the application, the complete Rigid-Flex circuit board may be manufactured either symmetrically with inward flexible layers, or asymmetrically with outward flexible layers (see Layer buildup for Rigid-Flex circuit boards).
We recommend the IPC-2223 Guidelines to circuit board designers for flexible circuit boards. This is available (at cost) from the website of the IPC (www.ipc.org).
