Our Prototyping Process
A streamlined 6-step process designed to get validated prototypes into your hands as quickly as possible.
Submit Design
Share your drawings, schematics, BOM, or even a rough sketch. Our engineering team reviews every detail.
DFM Review
We analyze your design for manufacturability, flag potential issues, and recommend optimizations before build.
Material Sourcing
Rapid sourcing from our extensive connector and cable inventory. Common components available same-day.
Prototype Build
Skilled technicians build your prototype using production-grade processes, tooling, and workmanship standards.
Test & Inspect
Every prototype undergoes continuity testing, dimensional inspection, and a full first article inspection report.
Ship & Support
Fast shipping with complete documentation. Our engineers support you through validation and into production ramp.
Prototyping Specifications
Quick-turn prototyping specifications for wire harness and cable assembly projects.
Seamless Prototype-to-Production Transition
The biggest risk in prototyping is building something that cannot be manufactured at scale. We eliminate that risk by using production tooling, processes, and materials from day one. When your design is validated, we ramp to volume production without re-tooling or re-qualifying.

“In my 15 years of manufacturing wire harnesses and cable assemblies, I've seen too many product launches delayed because the prototype couldn't be replicated in production. That's why we build every prototype with production tooling and processes. When you approve the prototype, you're approving the exact same build that ships in volume. No surprises, no re-qualification, no delays.”
Prototype Wire Harness & Cable Assembly Manufacturing Services
Getting a prototype wire harness or prototype cable assembly built quickly and correctly is one of the most critical steps in new product development. At OurPCB, we specialize in quick-turn prototyping that delivers production-grade samples in as little as 48 hours — with no minimum order quantity and full electrical testing on every unit.
Our prototyping service covers the complete range of wire harness and cable assembly types. Whether you need a simple two-wire pigtail with Molex connectors or a complex multi-branch automotive harness with hundreds of circuits, our engineering team handles it. We work from your engineering drawings, schematics, or even rough sketches — providing a complete DFM review before build to identify potential issues early.
What sets our prototyping apart is the use of production-grade processes from the first piece. Every prototype goes through the same cutting and stripping, crimping with force monitoring, and soldering processes used in volume production. This approach eliminates the common problem where a hand-built prototype performs differently from production units — because with us, the prototype is a production unit.
First Article Inspection (FAI) documentation accompanies every prototype shipment, including dimensional verification, continuity testing results, hi-pot testing data, and pull force verification for crimped terminals. This documentation not only validates your prototype but establishes the quality baseline for production runs.
For applications requiring environmental protection, our prototyping includes overmolding, potting, and heat shrink tubing application. We also prototype shielded cables with braiding for EMI-sensitive applications in medical and aerospace environments.
Our dual-factory model accelerates prototyping timelines. The China facility provides rapid prototype builds with full manufacturing capabilities, while our Philippines facility handles production ramp-up with US tariff-free advantages. Whether you are developing medical device cables under ISO 13485 or automotive harnesses requiring IATF 16949 compliance, our certified facilities support your quality requirements from prototype through production.

Prototyping FAQ
We have no minimum order quantity. You can order a single prototype wire harness or cable assembly. This allows you to validate your design without committing to volume production. Most customers order 1–5 pieces for initial prototyping and 10–50 pieces for design validation testing before moving to production.
Our standard prototype lead time is 5–7 business days from design approval. For urgent projects, we offer 48-hour expedited prototyping on cable assemblies using common connectors and materials from our in-house inventory. Lead time depends on connector availability and assembly complexity — our team confirms exact timing when you submit your design.
Yes, every prototype order includes a complimentary Design for Manufacturability (DFM) review. Our engineers analyze your design for potential issues — incorrect connector orientation, insufficient bend radius, strain relief concerns, wire gauge optimization — and provide feedback before the build begins. This catches problems early, reducing revision cycles and speeding up your time to market.
Absolutely. We deliberately build prototypes using production-grade processes, tooling, and materials. This means the same crimping applicators, soldering techniques, and testing fixtures used for your prototype carry directly into volume production. There is no re-qualification needed, which saves weeks during the transition from prototype to production.
Every prototype ships with a comprehensive First Article Inspection (FAI) report including dimensional measurements, continuity test results, hi-pot test data (if applicable), pull force verification for crimped terminals, and photographs of the completed assembly. We also provide a manufacturing process sheet that captures all build parameters for production repeatability.
We prototype virtually any wire harness or cable assembly type: automotive harnesses, medical-grade cables, industrial control panels, sensor assemblies, power distribution harnesses, data cables, RF/coaxial assemblies, and more. If it involves wires, connectors, and terminations, we can prototype it. Our dual-factory capability means we can handle everything from simple two-wire assemblies to complex multi-branch harnesses with 500+ circuits.
