Rigid-flex PCB Assembly

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 PCB applications include:

  • ABS sensors
  • CT scans
  • Digital cameras
  • Smart jackets
  • Cell phones
  • Barcode scanners
  • Pacemakers



By combining the properties of rigid and flexible PCBs, rigid-flex PCBs come with a host of benefits for both manufacturers and consumers.

  • Mechanical stability- Their basic structure consists of interchanging layers of rigid and flexible PCBs. This ensures that they’re both stable and flexible, facilitating easy installation in small spaces.
  • Connection reliability-With rigid-flex PCBs, you get greater stability and polarity, making connections easier and more secure with other components. You will also require fewer connector components with each application.
  • Dynamism-Along with repeatability and precision, you’ll enjoy greater flexibility with packaging.
  • Cost-effective-By using rigid-flex PCBs, you can cut down on the total expenditures.
  • High-density applications-Arguably, the best benefit of rigid-flex PCBs is that they can be used for a high-density device population. This is due to their flexibility, stability, and low space use.
  • High shock and vibration resistance-Electronic components are used in a wide range of items, some of which experience constant vibrations. With such devices, you won’t have to worry about damage as rigid-flex PCB is highly resistant to shock and vibration.
  • Cost-effective
  • Reduces package weight
  • Simplifies assembly
