Not sure if flexible circuits are right for your project? Still wondering about when and why to transition from rigid PCBs to flexible circuit solutions? Here are the top reasons why flexible circuits might be the better choice.

  1. Form Factor and Space Efficiency

Flexible circuits—also known as flex circuits or flexible printed circuits (FPCs)— are best when your project requirements include:

  • Tight geometries that constrict the spaces available for electrical components
  • Moving assemblies that must carry signals or currents through the moving parts
  • High reliability under mechanical stresses such as vibration, movement, and even thermal cycling. 
  • High efficiency, including both space and weight
  1. Dynamic Flexibility

Flexible circuits can withstand repeated bending and flexing without compromising their functionality. This dynamic flexibility is crucial for electrical products that require functions such as:

  • Wearable devices
  • Foldable screens
  • Medical devices with moving parts
  1. Weight Reduction: 

Lighter weight provided by flexible circuits due to thin and lightweight materials

  • Help make smaller devices easier to handle.
  • Helps Improve the overall performance and efficiency of large-scale product systems such as:
    • Airplanes
    • Satellites
    • Vehicles
    • Industrial equipment
  1. Improved Reliability: 

Flexible circuits often exhibit higher reliability compared to rigid boards, especially when subjected to dynamic stress or vibration. Their ability to flex without damage makes them suitable for products that experience:

  • Movement
  • Vibration
  • Thermal cycling

Therefore, if your products require a compact solution for tight spaces, need to bend without breaking, decrease weight, or be more reliable with movement, then flexible circuits are the smarter and more efficient electronic products.
