Flex and rigid-flex

Double-Sided Flex PCB Manufacturing for Denser Flexible Routing

XFPCB manufactures double-sided flex PCBs where routing density, vias, stiffeners and bend reliability must be balanced carefully.

Project Information for Quotation

XFPCB builds Double-Sided Flex PCB for products that need thin, bendable or integrated interconnects. We review the copper pattern, coverlay, stiffener, bend area and connector zone so the flexible circuit can fit the product mechanically and perform reliably in use.

For flex and rigid-flex projects, include the bend direction, bend radius, stiffener drawings, connector areas and whether the bend is static or dynamic. These details help XFPCB protect both electrical performance and mechanical reliability.

Engineering and Procurement Details

two copper layers

XFPCB reviews two copper layers against your submitted files, quantity and application requirements before confirming the build plan.

via placement

Clear via placement requirements help our team quote accurately, prepare production data and reduce avoidable clarification rounds.

bend radius

Our engineers confirm details for bend radius early, so your team can approve the order with clear next steps.

stiffener and connector review

Production notes for stiffener and connector review stay connected with the project to support repeat orders and future design revisions.

How XFPCB Controls the Build

For Double-Sided Flex PCB, XFPCB combines engineering review, manufacturing preparation, quality inspection and export communication so your purchasing team can move from RFQ to delivery with a clear build plan.

  • Bend radius, bend direction, coverlay openings and stiffener zones are checked from the drawing.
  • Copper routing in bend areas is reviewed for mechanical reliability.
  • Connector areas, adhesive, stiffener and assembly handling requirements are confirmed.
  • Finished flexible circuits are inspected for outline, exposed pads and electrical continuity.

Capability and Scope

Project AreaXFPCB Guidance
StructureCopper on both sides of the flexible dielectric
Common needMore routing without moving to a rigid-flex design
Production control pointDo not place vias in dynamic bend zones unless reviewed

Useful Terms

Coverlay
A protective polyimide film used instead of standard solder mask.
Stiffener
A reinforcement added under connectors or assembly areas.
Bend radius
The minimum bend curve expected during use.
Static bend
A flex area bent during installation but not repeatedly moved.

Double-Sided Flex PCB FAQs

What should I send to quote Double-Sided Flex PCB?

Send Gerber files, NC drill files, board outline, stackup notes, material, copper weight, surface finish, quantity and target lead time. For PCBA or assembly-related work, also send the BOM with manufacturer part numbers, pick-and-place data, assembly drawing, DNP notes and test expectations.

Can XFPCB review the files before production?

Yes. XFPCB can review manufacturability and quotation details before production starts. We check material choices, via structures, component package data, tolerance requirements and inspection requirements before release.

Can XFPCB support both prototype and production orders?

In most cases XFPCB can support both stages. Prototype builds help validate the design, while production planning controls repeatability, documentation, component supply and cost for future orders.

How can I reduce quotation delays?

Provide complete files, expected annual or batch quantity, destination country, special standards, inspection needs and the target schedule. If the design is still changing, tell us which details are fixed and which are under review.

Request a Quote for Double-Sided Flex PCB

Send your project information to XFPCB and our team will review the key manufacturing or assembly details. A complete RFQ helps us respond with a more accurate quote and a clearer production plan.

  • For bare PCB projects, include Gerber, drill, stackup, material, copper, finish, quantity and lead time.
  • For PCBA projects, include BOM, pick-and-place file, assembly drawing, test notes and approved alternatives.
  • For application-specific projects, share operating environment, reliability expectations and packaging needs.
