FPC Prototype Lead Time: From Gerber to Samples
Prototype turnaround is rarely a single number. Understand what drives FPC sample lead time and how to get a written schedule you can rely on.
Why lead time varies
A simple single-sided FPC and a multilayer rigid-flex build are different products with different process steps. Lead time varies with layer count, materials, stack-up, tooling and assembly requirements. Ask for an estimate tied to your specific stack-up and quantity rather than a single generic number. For an overview of what we manufacture, see our flexible PCB page.
File completeness is the fastest lever
Most delays start before production: missing Gerber layers, an incomplete BOM, or unclear finish requirements trigger back-and-forth review. Provide Gerber files or drawings, a BOM, target quantity, layer count, stack-up, material, copper weight and finish up front. Complete files move into review faster; incomplete files add time.
Stack-up complexity sets the baseline
Standard single- and double-sided flexible circuits generally involve fewer process steps than multilayer or rigid-flex builds. Confirm how complexity affects your schedule rather than assuming a fixed turnaround.
Engineering review protects your schedule
A review of the submitted files and project requirements before production can surface issues that would otherwise appear after the sample arrives. Fanjuda reviews the submitted files and project requirements before confirming production feasibility and lead time. For details of the prototype service and what to prepare, see our FPC prototype service page.
Prototype-to-volume transfer should be explicit
How a validated prototype is transferred to volume production affects consistency. Buyers should confirm how prototype specifications will be transferred to volume production before committing to mass production.
SMT assembly timing is confirmed separately
If assembled prototypes are required, coordinated SMT assembly support is available and assembly timing is confirmed separately with your order.
Getting a written schedule
Provide complete files and requirements, ask for a written schedule after engineering review, and confirm what happens if the review finds issues. A written schedule should be confirmed before production begins.
