What is a Rigid Flex PCB?

Rigid flex PCBs are a unique type of circuit board that combine both flexible and rigid technologies. These boards typically consist of several layers of flexible circuit substrates that are attached to one or more rigid boards, either internally or externally, depending on the application’s design requirements. The flexible substrates are designed to remain in a constant state of flex, and can be molded into the desired shape during manufacturing or installation.

Designing rigid flex PCBs requires greater attention to detail than designing traditional rigid boards, as they operate in a 3D space that offers improved spatial efficiency. By utilizing this additional dimension, designers can twist, fold, and roll the flexible substrates to optimize the final package’s shape for the application.

Rigid Flex PCB Technology and Production Process

Rigid flex PCB technology is a well-established and reliable solution for producing prototypes or large-scale production quantities. The use of flexible PCBs is particularly beneficial in overcoming space and weight issues, providing greater spatial degrees of freedom.

It is important to carefully consider flex-rigid solutions and assess available options during the early stages of PCB design to maximize benefits. Collaboration between the PCB fabricator and designer is essential during this phase to ensure coordination and account for final product variations.

The manufacturing process for rigid flex PCBs is more complex and time-consuming compared to rigid FR4 board fabrication. This is due to the unique handling, etching and soldering processes required for the flexible components of the rigid flex assembly.

At our rigid flex PCB manufacturing facility, we have the expertise, facilities and equipment necessary to produce high-quality rigid flex PCBs. We work closely with our clients throughout the design and fabrication process to ensure the highest level of quality, reliability and efficiency. Whether you need a rigid flex prototype or large-scale production quantities, we have the flexibility to meet your needs.

Benefits of Rigid Flex PCBs

Rigid flex PCBs offer numerous benefits that make them an ideal solution for a wide range of applications. By utilizing 3D space, rigid flex PCBs can minimize space requirements and reduce overall system weight by eliminating the need for connectors and cables between individual rigid parts. The resulting maximization of space often leads to fewer parts being required, simplifying assembly and reducing costs.

In addition, rigid flex PCBs feature fewer solder joints, resulting in higher connection reliability. Handling during assembly is also easier compared to flexible boards, and simplified PCB assembly processes further enhance ease of use. Integrated ZIF contacts provide simple modular interfaces to the system environment.

Rigid flex PCBs also simplify testing conditions, allowing for complete testing prior to installation. This results in significantly reduced logistical and assembly costs with flex-rigid boards. Additionally, the increased complexity of mechanical designs improves the degree of freedom for optimized housing solutions.

At our rigid flex PCB manufacturing facility, we provide high-quality products that deliver these benefits and more. Our experts work closely with our clients throughout the design and fabrication process to ensure the highest level of quality, reliability, and efficiency. Whether you require a rigid flex prototype or large-scale production quantities, we have the flexibility to meet your needs.

Rigid Flex Design and Fabrication Issues

Design and fabrication issues must be taken into account during the production of rigid flex PCBs. During the design process, final product size variations should be considered, as the flexible polyimide core will shrink once the bonded copper foil is etched away. This variation must be accounted for in the design process to ensure that the final product meets specifications.

The final assembly process requires flex portions to be bent into shape, which can cause stress fractures in the flex laminations. Therefore, it is crucial to have experienced experts in rigid flex fabrication to ensure that the final product meets all standards and requirements.
