Rigid-Flex PCB with ShinePCB

Rigid-flex boards join rigid sections with flexible layers in one construction. We review bend areas, transitions, stiffeners and assembly constraints against your drawing so the design works both in production and in the product.

  • Rigid and flexible layer construction
  • Bend areas and transition zones
  • Coverlay and stiffener placement
  • Assembly and handling constraints

Aerospace-style and ruggedised assemblies

From prototype to production

Every order follows the same controlled sequence. Prototype and production requirements are reviewed separately.

  1. File review

    Gerber or ODB++, drill data, drawing and quantities are checked for completeness.

  2. Engineering questions

    Open points on manufacturability, materials or special processes are sent before quotation.

  3. Stack-up and material

    Construction, laminate and finish are confirmed with you and written into the order.

  4. Fabrication

    The order is released to the facility whose process and qualification fit the requirements.

  5. Inspection and test

    Inspection and electrical test follow the methods agreed for your order.

  6. Packing and delivery

    Boards are packed and shipped under the confirmed delivery terms.

What to send for a PCB review

Start with the details you have — engineering will request anything else needed for the review.

Files and details for a PCB review

  • Gerber (RS-274X) or ODB++ data with drill files
  • Fabrication drawing with material, thickness and finish
  • Stack-up and impedance targets, if any
  • Quantity for prototype and for production
  • Special requirements such as IPC class, testing or packaging

Technical files stay private

Customer Gerber, BOM and design data are managed under an ISO/IEC 27001 information security system and shared only within your project.

Rigid-Flex PCB FAQs

What should my drawing show?

Mark the rigid and flexible areas, bend locations and any stiffeners, together with the layer construction.

Can rigid-flex boards be assembled with components?

Yes. Assembly needs are reviewed with the construction so the board can be supported during assembly.
