What is Rigid-Flex PCB

Rigid-Flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation.

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 rigid flex designers can twist, fold and roll the flexible board substrates to achieve their desired shape for the final application’s package.

The Advantages of Flex-Rigid PCB Technology

While this type of flexible circuit may be more expensive to design and produce, it does offer a number of important advantages. For instance, the reduced size makes it easier to fit more components into a smaller space. This can actually help to lower overall system costs. Additionally, because they require the need for fewer interconnects and related parts and components, these flexible circuit board can also prove to be more reliable and require less maintenance in the long run.

As with all types of flexible circuit boards, the flex-rigid PCB will perform well in even the harshest environments, especially those featuring extreme heat. A rigid flex board is also easy to test, making it well-suited for prototyping.

Benefits of Rigid-Flex PCBs

  • To minimize the space required, utilize 3D technology.

  • Maximizing space can often result in a lower count of parts.

  • By eliminating the necessity of connectors and cables between individual rigid components, the overall size and weight of the board and system can be decreased.
  • For improved connection reliability, the number of solder joints has been reduced.

  • Simplified PCB assembly processes.

  • Assembling is made easier with this product compared to flexible boards.
  • Modular interfaces to the system environment are made simple with Integrated ZIF contacts, ensuring a seamless and efficient integration process.

Rigid-Flex Circuits are composed of laminated flexible and rigid substrates, offering both strength and dynamic adaptability in the design. The rigid portions are utilized for component holders while the flexible substrates function as interconnection pathways.



The Multilayer Flex circuits manufacturing process involves using adhesive layers to bond together several conductive layers, including both double and single sided Flexible constructions. These layers are then interconnected through plated Vias, providing circuit protection and electrical insulation. A Coverlay, typically made of Polyimide, is also used in the manufacturing process.



The most commonly utilized type of Flex Circuits is a single sided Flex PCB, made up of a thin conductive layer that is hot-pressed and bonded with a flexible dielectric film for both electrical insulation and weather protection.



Using a Polyimide film as a base layer, two separate conductive layers are affixed and fused onto both sides of the film. Plated Through Holes (PTH) serve as interconnections between the copper layers, while added layers of polyimide on each side of the panel provide insulation for the double sided Flex Circuits.



Flex Circuits, also referred to as Flex PCB, are revolutionizing the electronics industry by introducing a new method of creating products. Originally created as a wire harness replacement, Flexible Circuit technology is challenging traditional fabrication methods where PCB size was a limiting factor in electronic design.
