Rigid-flex PCB technology benefits:

  • Reducing device weight
  • Reducing box-building space
  • Enhancing durability
  • Enhancing reliability

Some challenges as following:

  • Evaluation and confirmation the different rigid or flex materials with PCB fabrication supplier
  • Evaluation and confirmation all details for any layer connecting specification with PCB fabrication supplier
  • All components placement and profile routing for flex area is different to rigid board
  • 3D describing rigid and flex sections for box-building
  • Verification of flexible motions and critical action cycles

The key items for PCB design to PCB manufacturer as below: (Guideline of Rigid-flex PCB design)

  • Explain the PCB materials clearly
  • Substrate Material, most common is polyimide, flexible, tough, incredibly heat resistant with reasonably stable in expansion and contraction to temperature fluctuations.
  • Coverlay Films
  • PCB fabrication and assembly processes

(The two items would be most important to discuss with PCB manufacturer)

Rigid-Flex circuitry provides a simple means to integrate multiple PCB assemblies and other elements such as display, input or storage devices without wires, cables or connectors, replacing them with thin, light composites that integrate wiring in ultra-thin, flexible ribbons between sections. In rigid-flex packaging, a flexible circuit substrate provides a backbone of wiring with rigid multilayer circuit sections built up as modules where needed.

Flex and Rigid-Flex applications also provide increased reliability. Mean time between failure rates (MTBF) typically exceed those of standard PCB sets with discrete wires and connectors, often becoming the choice of companies and engineers alike for its dependable and consistent performance.

Highfive has extensive experience, product knowledge and technical competency in this area. Flex & Rigid-Flex expertise can also be found in various medical and health related test equipment, computing networks, and various scientific and industrial applications.

Rigid-Flex product types include:

Type 1: Single sided flexible material with or without shield(s) or stiffener (one conductive layer).

Type 2: Double sided flexible material with or without shield(s) or stiffener (two conductor layers with plated through holes.

Type 3: Multilayer flexible material with or without shield(s) or stiffener (more than two conductor layers) with plated through holes and HDI.

Type 4: Multilayer rigid and flexible material combinations (more than two conductor layers) with plated through holes and HDI.
