Flexible PCB Prototype – Flex PCB Prototyping Service
Before committing to mass production, every flexible PCB design needs validation. Will it fit the enclosure? Will it withstand the required bend radius? Are all connections correct?
Our flexible PCB prototyping service is designed for rapid iteration and design validation. With fast turnaround (7-10 days) , low minimum quantities (as few as 5 pieces) , and flex-specific DFM review included, we help you get your design right before scaling to production.
Why Prototype Your Flexible PCB Design?
| Reason | Benefit |
|---|---|
| Validate fit | Test if the flex board fits your curved enclosure |
| Test bend radius | Verify the board bends without cracking |
| Verify electrical function | Confirm all connections work as designed |
| Identify design issues | Catch errors before mass production |
| Test assembly process | Ensure stiffeners and components align |
| Iterate quickly | Make revisions and retest in days, not weeks |
| Reduce risk | Avoid expensive mass production rework |

| 3. Receive quotation | Detailed pricing for prototype quantity | 24 hours |
| 4. Confirm order | Approve and pay | Same day |
| 5. Prototype fabrication | Built to your specifications | 7-10 days |
| 6. 100% electrical test | Flying probe test | Included |
| 7. Ship to you | DHL/FedEx/UPS | 2-5 days |
What We Check in Flex DFM Review
| Check | Why It Matters for Prototypes |
|---|---|
| Bend radius (≥10x static, ≥30x dynamic) | Prevents copper cracking |
| Vias in bend areas | Vias crack when bent – flag for removal |
| Trace direction vs. bend axis | Traces perpendicular to bend = less stress |
| Coverlay coverage | Coverlay protects flex – no solder mask |
| Stiffener placement | Must be outside bend areas |
| Copper type specification | RA copper required for flex |
| Annular ring | Prevents via breakout |
| Trace width/spacing | 3/3 mil minimum for flex |
Common Flex Prototype Design Issues We Catch
| Issue | Consequence | Our DFM Alert |
|---|---|---|
| Vias in bend area | Cracking during flexing | Red flag – move vias |
| Bend radius too tight | Copper fatigue, early failure | Increase radius or reduce thickness |
| Solder mask on flex | Cracks, poor flexibility | Use coverlay instead |
| 90° trace corners in bend | Stress concentration | Use 45° or rounded corners |
| Stiffener crossing bend line | Prevents bending, stress point | Move stiffener outside bend area |
| Missing coverlay openings | Pads not accessible for soldering | Add coverlay openings |
Applications That Typically Need Flex Prototypes
| Application | Why Prototype is Critical |
|---|---|
| Wearable device | Fit and comfort testing – must conform to body |
| Medical device | Regulatory submission – working hardware required |
| Foldable phone | Complex folding – multiple iterations needed |
| Laptop hinge design | Dynamic flexing – test thousands of cycles |
| Robotic arm cable | Dynamic flexing – test bend life |
| Automotive sensor | Fit in tight housing – verify dimensions |
| Aerospace harness replacement | Weight and fit validation |
Prototype to Production – Seamless Transition
| Stage | Quantity | Lead Time | Purpose |
|---|---|---|---|
| Prototype (first article) | 5-20 pieces | 7-10 days | Design validation, fit testing |
| Pilot run | 50-200 pieces | 10-12 days | Process validation, market testing |
| Production | 500-100,000+ pieces | 12-15 days | Mass production, cost optimization |
Use the same supplier for all stages – no re-qualification needed.
