Flex PCB Manufacturer Guide: Materials, Bending, and Cost Factors

A beginner-friendly guide to flexible PCBs, including polyimide material, bend radius, stiffeners, and common design mistakes.

Flexible PCBs solve packaging problems that rigid boards cannot. They reduce connector count, save space, and allow mechanical movement, but they require more careful design.

What affects flex PCB cost

  • Layer count
  • Polyimide thickness
  • Stiffeners
  • Bend area design
  • Surface finish

Important design advice

Avoid placing vias in dynamic bend zones, keep copper transitions smooth, and define whether the flex is static-bend or dynamic-bend.
