Rigid-Flex PCB Manufacturing Services

Rigid-flex boards integrate rigid sections for component density with flexible regions for dynamic bending or folding—ideal when connectors and harnesses must disappear.

Service overview

Successful rigid-flex programs document bend radii, stiffener placement, coverlay openings, and adhesive systems. We review those details with your mechanical and electrical owners before release.

Rigid-flex is a core specialization for MOZPCB. Each quote includes a review of the flex stackup—polyimide core and coverlay selection, adhesive versus adhesiveless constructions, and whether your bend zones are static (fold-to-install) or dynamic (repeated flexing)—because those choices drive both reliability and cost.

Applications span wearables, portable medical devices, and industrial equipment where vibration and repeated motion demand disciplined flex regions.

What we offer

  • Rigid-flex structures with documented bend zones and stiffener strategy
  • Constructions from simple 2-layer flex with rigid caps to multilayer rigid-flex with buried flex layers
  • Flexible circuit sections processed with appropriate coverlay and access openings
  • Adhesiveless polyimide constructions for tighter bends and higher reliability where specified
  • Space-saving layouts that reduce connectors, harnesses, and hand-soldered jumpers between rigid subsystems
  • DFM guidance on pad anchors, tear drops, and strain relief near flex transitions
  • Stiffener options in FR-4, polyimide, and stainless steel per your drawings
  • Assembly of rigid-flex boards including fixturing for non-flat panels

Technical capabilities

  • Static bend designs typically down to 10x flex thickness; dynamic bends reviewed case by case
  • Multiple flex arms, air gaps, and bookbinder-style constructions (design-dependent)
  • Flex layer counts from 1 to 6+ within rigid-flex stackups, subject to design review
  • Selective stiffeners and PSA attachment when drawings specify them
  • Impedance-controlled flex segments when stackups support it
  • ZIF connector tail thickness control and gold plating for direct-insertion tails
  • Coverlay openings, dams, and windowing aligned to your assembly plan

Common applications

  • Wearables and hearables with dynamic motion
  • Medical electronics with articulated probes or patient interfaces
  • Foldable and hinged consumer devices where cables cannot fit
  • Industrial control devices exposed to vibration and thermal cycling
  • Aerospace instrumentation where weight and connector count must fall

FAQ

What mechanical information is most important for rigid-flex?
Bend radius, number of dynamic bends, stiffener drawings, and any connector overhang requirements. Mechanical PDFs alongside fab files reduce rework.
What is the minimum bend radius for a rigid-flex PCB?
A common rule of thumb is 10 times the flex-section thickness for static bends and 100 times for dynamic bends. The real limit depends on copper weight, number of flex layers, and whether the construction is adhesiveless—share your bend geometry and we will confirm during DFM review.
How does rigid-flex compare in cost to a rigid board plus cables and connectors?
The bare rigid-flex board costs more than an equivalent rigid board. Total system cost is often lower once you remove connectors, cable assemblies, and the labor and reliability risk of hand-attached harnesses—especially at higher volumes or in vibration-prone products.
Do you support both static and dynamic flex applications?
Yes. Static (flex-to-install) designs allow tighter bends and simpler constructions. Dynamic applications need adhesiveless materials, thinner copper, and neutral-axis routing, which we review against your motion requirements before quoting.
Can rigid-flex include impedance-controlled layers?
Yes, when the stackup and materials support your targets. Include impedance tables and tolerance expectations in the RFQ.
