Flex-rigid PCB

Flex-Rigid PCB

Flex-rigid PCBs are printed circuit boards highlighted by both rigid and flexible areas that make them ideally suited for a wide range of applications. The typical rigid-flex PCB circuit includes two or more conductive layers that comprise either flexible or rigid insulation material between each one - the outer layers may have either exposed pads or covers. Conductors are found on the rigid layers, while plated through-holes are found in both the rigid and flexible layers.

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.
