Rigid-Flex Printed Circuit Board

pcb rigid flexYour Leading Rigid-Flex PCB  Supplier

Rigid-flex PCBs are boards that combine the best of flexible and rigid-board technology

Designs vary greatly, and can be combined with a wide range of materials to support multiple use cases in a constant state of flex — often a flexed curve created during the manufacturing process, or can be made during final installation.

Why You Need Rigid Flexible Circuits From MCL

These printed circuit boards create a more challenging design for rigid-flex manufacturers, but we’ve been able to supply successful designs with full compliance and reliability. By engineering these in a 3D environment, we’re able to achieve spatial efficiency and incorporate folds and flexes that can help you meet a desired shape that works best with your application.


Layout Recommendations

Rigid-flex PCB  suppliers like MCL provide guidance on layouts and bends to keep your equipment safe. We wanted to present a quick overview to help you understand the thickness and other requirements you may need for your design.

Circuit Construction Bend Radius Calculation
1 Layer (single-sided) Flex Thickness x 6
2 Layer (double-sided) Flex Thickness x 12
Multi-Layer Flex Thickness x 24

Other design tips include:

  • Avoid 90˚ bends whenever possible.
  • Gradual bends are always safer.
  • Bend radius is measured from the inside of the bend.
  • Conductors running through a bend need to be perpendicular to the bend.
  • Use curved traces instead of traces with corners.
  • Traces should be perpendicular to your bend.


Your specific rigid-flex printed circuit board will be a custom design and production. However, to get you started thinking about what to consider, we wanted to share with you just a small selection of the materials that can be used for your project. This flexibility and capability makes us one of the leading rigid-flex PCB suppliers the United States has to offer.
