What is a Rigid-Flex PCB?
Rigid-Flex PCBs combine the best of both rigid and flexible circuit technologies, making them essential in modern electronics. These circuit boards feature a combination of rigid sections for stability and flexible sections for dynamic, space-saving interconnections. The flexible portions consist of a thin, flexible insulating polymer film with conductive circuit patterns, often coated with a protective polymer layer, while the rigid sections provide structural support.
Since their development, Rigid-Flex PCBs have become vital for complex electronic applications that require both durability and flexibility. At Unit Circuits, we specialize in customized Rigid-Flex PCB solutions, ensuring reliable performance and high-quality interconnections for even the most demanding electronic products.
High-Temperature and High-Density Applications
Rigid-Flex PCBs are often constructed using polyimide or similar polymers in their flexible sections, which offer superior heat dissipation compared to traditional rigid circuit board materials. This makes them ideal for deployment in challenging environments where high temperatures could compromise the performance of purely rigid boards.
At Unit Circuits, our Rigid-Flex PCBs are engineered to withstand extreme temperatures ranging from -200°C to 400°C, making them particularly suitable for demanding applications such as borehole measurements in the oil and gas industry. The combination of rigid and flexible layers provides both stability and adaptability, making Rigid-Flex PCBs a top choice for advanced industrial sensor technologies.
In addition to high-temperature resistance, our Rigid-Flex PCBs offer excellent chemical resistance, radiation resistance, and UV exposure durability. Coupled with the ability to manage impedances in high-density designs, these features provide manufacturers with robust, high-performance electronic components tailored for complex and demanding applications

Why Not Make All Circuit Boards Rigid-Flex?
Rigid-Flex PCBs offer significant benefits by combining the strengths of both rigid and flexible circuit boards. However, they aren’t the best solution for every application, especially when cost efficiency is a major consideration. Rigid circuit boards are generally more economical to manufacture and assemble, particularly in high-volume production environments.
For most innovative products, the ideal solution often involves a combination of rigid and flexible PCBs. This approach allows for the use of flexible circuits where necessary, while maintaining the cost advantages of rigid boards in other areas.
At Unit Circuits, we specialize in Rigid-Flex PCBs, which are commonly used in applications like laptop computers and medical devices. These designs integrate rigid boards with flexible circuits, providing a versatile and reliable solution that meets a wide range of engineering requirements.
If you’re uncertain whether your product would benefit more from rigid, flexible, or Rigid-Flex PCB designs, our expert team is ready to assist. Contact us for a consultation to determine the best PCB solution for your specific needs.
