Rigid-Flex PCB
Project review for rigid-flex PCBs that combine rigid circuit sections with flexible interconnect areas and require close stack-up, material, and bend-zone coordination.
MWX PCB reviews project requirements and coordinates feasibility, engineering feedback, inspection expectations, and production follow-up through the manufacturing route confirmed for the project.
Capability, materials, timing, inspection scope, and production resource are confirmed case by case after the actual files and requirements are reviewed.
RIGID-FLEX PCBTypical Applications
Application examples help frame the review; they are not a blanket capability or compliance commitment.
Capability Review
- Rigid-flex stack-up review
- Flexible layer and coverlay coordination
- Bend-area and transition-zone review
- Stiffener and mechanical requirement communication
- Assembly-oriented panel and handling review
Project-Specific Selection
- Polyimide flexible materials
- Rigid FR-4 sections selected to project requirements
- Coverlay, adhesive, and stiffener options based on design needs
- Final material system confirmed for the reviewed production route
These are individual reference limits, not a promise that every limit can be combined in one design. Final feasibility depends on the complete Gerber data, stack-up, materials, quantity, quality scope, and production requirements and is confirmed through project-specific engineering review coordinated by MWX PCB.
Common Manufacturing Risks
- Copper features placed in dynamic bend areas
- Abrupt trace-direction changes near transitions
- Coverlay opening and annular-ring conflicts
- Rigid-to-flex transition stress
- Dimensional control and handling during assembly
Inspection & Verification
- Continuity and electrical test follow-up
- Visual review of flex and transition areas
- Dimensional checks against approved drawings
- Microsection or reliability evidence when specified
Timing Confirmed After Review
Lead time depends on layer construction, material system, tooling, mechanical complexity, and required reliability verification.

Rigid-Flex PCB Project Questions
Do you review bend-area design risks?
Yes. Bend radius, copper placement, transition zones, coverlay, and mechanical constraints are included in the project review.
Can rigid-flex projects use a standard stack-up?
Some constructions are common, but the final stack-up must be reviewed against the mechanical and electrical requirements of each project.
What mechanical information should be supplied?
Provide board outline, bend locations, bend radius, stiffener details, connector areas, assembly constraints, and applicable drawings.
