What Is a Quick Turn PCB Prototype?
A Quick Turn PCB Prototype refers to a full-cycle service that includes PCB design, fabrication, and assembly-completed within an accelerated timeframe. Compared to traditional prototyping, our optimized workflow ensures rapid validation of design feasibility during early-stage development.
Common use cases include:
- Prototype Verification
- Design Iteration
- Line-down Recovery
- Pilot Run

Technical Capabilities & Process Control
We offer full in-house prototyping and assembly capabilities, ensuring consistency between sample and mass production:
- SMT Lines: 7 Panasonic high-speed SMT lines + 2 DIP lines
- Placement Precision: Supports 01005 components, 0.25 mm BGA, 12-zone nitrogen reflow
- Inspection: AOI + X-Ray solder joint inspection (resolution up to 5μm)
- PCB Fabrication: Partnered with certified fabs, supporting 1–32 layers, HDI, rigid-flex, high-speed boards (min trace/space: 3mil)
- Surface Finishes: ENIG, HASL, OSP, and more
- Certifications: ISO9001,ISO14001, ISO13485, IATF16949
- Medical-grade defect rate: 297ppm
- Automotive/Industrial yield: 99.82% / 99.78%

End-to-End Delivery Workflow
From PCB prototyping to full PCBA assembly, we provide a one-stop service:
- Engineering file review & reliability analysis
- PCB fabrication (standard 2-layer boards ship in 24h; complex multilayer boards in 72h)
- SMT assembly (daily capacity: 14 million placements; monthly: 300K+ boards)
- DIP insertion
- Functional testing
- ESD vacuum packaging & shipment
Typical PCBA sample lead time: 10–15 days Expedited medical/automotive samples: 72-hour fast-track available (requires pre-approved drawings & material readiness) Urgent pilot runs: minimum 10 pcs, launch within 48 hours (launch ≠ delivery)
