Q: Why rigid-flex? What advantage does a rigid-flex printed circuit have comparied with rigid & flex board?
A: Combined with FPC and PCB advantages, rigid-flex circuits provides reliable 3 dimensional circuitry application with stable platform for stiffeners, components, heat steaks, pins and other possible value added items.Rigid-flex advantages & benefits:
  • Better reliability, signal integrity, noise reduction, and impedance control.
  • Reduces mechanical space and device weight.
  • Improves design freedom.
  • HDI microvia.
  • Cost-saving alternative to multi-layer FPC.
