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.
