Dear Customers

PCBCart will have the official holidays since Jan. 24th through Feb. 3rd for Chinese Lunar New Year. Please schedule your order earlier (about half a month earlier for bare PCB orders and start assembly orders from now on) to ensure that the products could be manufactured and delivered on time before our holiday. If the orders with delivery date scheduled around those days need to be delivered before holiday, please contact us.

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.

Flex-Rigid PCB Solutions of the Highest Quality

Currently, PCBCart has served companies in industries such as medical, telecommunications and manufacturing with our superior quality Flex-rigid PCB manufacturing services. We have an in-house quality control department to ensure your boards fabricated and assembled properly - we also guarantee the quality of all parts and components. Our engineers will even perform a Design for Manufacture (DFM) check at no additional charge.
