Description
What is a Rigid Flex PCB?
A rigid flex printed circuit board (PCB) is a hybrid circuit board design that integrates elements from both hardboard and flexible circuits. Rigid flex PCBs are rigid at some points on the board and flexible at others. Because of this, rigid flex circuits can be folded or continuously flexed while maintaining the shape of areas that need extra support. The circuits are typically multi-layered and are comprised of flexible circuit substrates joined with rigid boards. The flexible layers are buried internally and completely penetrate the rigid sections of the PCB.
Rigid Flex PCB Technology and Production Process
Whether producing a rigid flex prototype or production quantities requiring large scale Rigid-Flex PCBs fabrication and PCB assembly, the technology is well proven and reliable. The flex PCB portion is particularly good in overcoming space and weight issues with spatial degrees of freedom.
Careful consideration of Rigid-Flex solutions and a proper assessment of the available options at the early stages in the rigid-flex PCB design phase will return significant benefits. The Rigid-Flex PCBs fabricator must be involved early in the design process to ensure the design and fab portions are both in coordination and to account for final product variations.
The Rigid-Flex manufacturing phase is also more complex and time-consuming than rigid board fabrication. All the flexible components of the Rigid-Flex assembly have completely different handling, etching, and soldering processes than rigid FR4 boards.
Features of Rigid Flex PCB
Rigid flex designs are more challenging than the design of a typical rigid board environment, as these boards are designed in a 3D space, which also offers greater spatial efficiency. By being able to design in three dimensions designers can twist, fold and roll the flexible board substrates to achieve their desired shape for the final application’s package.

Benefits of Rigid Flex PCB
• Space requirements can be minimized by applying 3D
• By removing the need for connectors and cables between the individual rigid parts, the board size and overall system weight can be reduced.
• By maximizing space, there is often a lower count in parts.
• Fewer solder joints assure higher connection reliability.
• Handling during assembly is easier in comparison with flexible boards.
• Simplified PCB assembly processes.
• Integrated ZIF contacts provide simple modular interfaces to the system environment.
• Test conditions are simplified. A complete test before installation becomes possible.
• Logistical and assembly costs are significantly reduced with Rigid-Flex boards.
• It is possible to increase the complexity of mechanical designs, which also improves the degree of freedom for optimized housing solutions.
