Rigid Flex

There are many excellent possibilities for circuits designed primarily as a flex circuit.

Rigid Flex

A blend of rigid and flex emphasizing the best of both constructions, adding complimenting capabilities that neither possess alone. In its most typical configuration, the rigid-flex is as a series of rigid PCBs joined by integrated flex circuits (with emphasis on the high percentage of rigid area content). There are many excellent possibilities for circuits designed primarily as a flex circuit with the addition of integrated rigid areas. The rigid areas provide excellent hard mount points for components, connectors and chassis while flex areas offer dynamic flexing, flex to fit, and component mounting poised to take advantage of these low mass and vibration resistant zones. This blending leads to creative solutions for your most demanding applications.

Benefits of Rigid-FlexRigid Flex

  • Using the third dimension creates an optimal solution for applications with extreme space limitations
  • Replaces bulky wire harnesses with a compact, yet robust design
  • Flexible assemblies reduce connectors as well as labor, yield, transmission and reliability issues
  • These hybrid circuits can have up to sixteen layers
  • Optimized for the rigors of aerospace, medical and defense markets
