PCB Copy in Shanghai — From Sample Board to Production Files
PCB copy in Shanghai means you ship a single working or non-working board to our Pudong-district facility and receive a complete engineering package: Gerber/ODB++ fabrication data, a component-level BOM with manufacturer part numbers, and a reconstructed schematic — typically within 5–8 working days. Our lab sits inside China’s largest electronics supply chain, which cuts turnaround on component identification and cross-referencing by days compared to labs outside the country.
Why Choose Shanghai for PCB Copy Services?
Shanghai is not just a shipping hub. It hosts the densest concentration of component distributors, PCB fabricators, and assembly houses in eastern China. When our engineers perform a PCB copy in Shanghai, they can physically verify replacement components the same afternoon at the Beihai or SEG electronics markets, or pull datasheets from domestic distributor databases that aren’t indexed by Octopart or Digi-Key.
For overseas buyers, Shanghai also offers the most frequent direct cargo flights to North America, Europe, Southeast Asia, and the Middle East. A board shipped via DHL or FedEx from most global cities lands at Pudong International within 2–3 business days. Return shipments — your original board plus a USB drive of deliverables — follow the same express lanes.
Proximity to Fabrication
Once you have your Gerber files, prototype or production orders can be placed with any of the 200+ PCB fabricators within a 300 km radius (Kunshan, Suzhou, Jiangyin, Taicang). We routinely coordinate hand-offs so that your copied files go straight into fabrication without an extra shipping cycle. That shaves 3–5 days off the total replication timeline compared with routing files through a separate country.
What Does the PCB Copy Deliverable Package Include?
| Deliverable | Format | Details |
|---|---|---|
| Gerber fabrication files | RS-274X / Gerber X2 | All copper layers, solder mask, silkscreen, drill files, board outline |
| PCB source project | Altium / KiCad / Eagle (specify) | Editable project with net connectivity |
| Bill of Materials | Excel (.xlsx) | Reference designator, value, package, MPN, supplier link |
| Schematic | PDF + editable source | Hierarchical sheets for designs >200 components |
| Stackup report | Layer thickness, prepreg, copper weight, impedance notes | |
| Pick-and-place data | CSV | X/Y coordinates, rotation, side — ready for SMT |
Every file set undergoes a design-rule check (DRC) before release. We flag any trace/space violations below 3 mil / 0.076 mm and confirm via-to-pad annular ring compliance per IPC-2221B Class 2 defaults unless you specify Class 3.
How the Shanghai PCB Copy Process Works
Step 1 — Ship Your Board
Pack one sample (two if the board is double-sided with BGA components — one for X-ray, one kept intact). Use anti-static bags and rigid packaging. Declare as “electronic sample for engineering analysis, no commercial value” on customs paperwork. Most shipments clear Shanghai customs within 24 hours.
Step 2 — Intake & Imaging
We photograph every layer under controlled lighting, then scan with a 2400 DPI optical scanner. For boards with 6 or more layers, we perform controlled chemical de-lamination to expose internal copper. Blind and buried vias are mapped using micro-section cross-cuts and X-ray imaging on our Dage Quadra 7 system.
Step 3 — Reverse Engineering
Engineers rebuild the schematic net by net, starting from power rails and working outward to signal paths. Component values are confirmed with LCR meters (Keysight E4980A) and, where needed, decapping for IC markings that have been sanded or laser-etched. Typical accuracy: 99.5%+ net correctness on boards up to 16 layers.
Step 4 — Verification & DRC
The reconstructed Gerber set is imported into CAM350 for a layer-by-layer overlay comparison against the original scan images. Deviations greater than 0.5 mil trigger a manual review. We run electrical rule checks and, for impedance-controlled designs, recalculate stackup targets using Polar Si9000.
Step 5 — Delivery
Files are encrypted and uploaded to a secure portal within your NDA-protected project workspace. The physical board ships back to you the same day, unless you authorize us to forward it directly to a fabricator.
Key Advantages of PCB Copy in Shanghai Over Other Locations
Clients often ask why they should route their board through Shanghai rather than a domestic lab or a facility in another Asian city. The advantages are concrete and measurable:
- Component verification speed: Same-day physical cross-referencing at local markets and distributor warehouses — no waiting for samples to arrive from overseas.
- Fabrication hand-off: Gerber files can enter production at nearby fabs within hours of delivery, eliminating a second international shipping leg.
- Customs efficiency: Pudong Free Trade Zone processes engineering samples in under 24 hours; bonded warehouse options available for sensitive boards.
- Flight frequency: 50+ daily international cargo connections mean faster inbound and outbound transit than any other mainland China city.
- Engineering talent pool: Access to graduates from Jiao Tong, Fudan, and Tongji universities — deep bench for complex multi-layer and HDI projects.
Board Complexity & Turnaround
| Layer Count | Typical Turnaround | Starting Price Range (USD) |
|---|---|---|
| 1–2 layers | 3–5 working days | $300 – $600 |
| 4 layers | 5–7 working days | $600 – $1,200 |
| 6–8 layers | 7–10 working days | $1,200 – $2,500 |
| 10–16 layers | 10–15 working days | $2,500 – $5,000 |
| 18–28 layers / HDI | 15–25 working days | Quote required |
Rush service (50% surcharge) is available for 2–8 layer boards and cuts turnaround roughly in half. Boards with sequential lamination HDI (≥2 stacked microvias) or rigid-flex construction require a feasibility review before we commit to a timeline.
What Can Go Wrong — and How We Handle It
Corroded or fire-damaged boards: If copper layers are partially dissolved, we reconstruct missing traces from the schematic context and flag every assumed connection in the deliverable notes. Accuracy drops to approximately 95–97% in heavily damaged zones — we disclose this upfront.
Sanded IC markings: About 15% of boards we receive for PCB copy in Shanghai have intentionally obscured chip markings. Our engineers cross-reference pin count, package, and circuit context against known device families. When a definitive match isn’t possible, we list two or three candidate parts and note the uncertainty.
Buried via registration errors: On boards older than 10 years, layer-to-layer registration can drift beyond spec. We measure actual offsets and adjust the Gerber output so the new fabrication run uses corrected coordinates rather than replicating the original error.
Shipping to Shanghai from Key Regions
Clients across Asia benefit from next-day or same-region express delivery. If you are arranging PCB copy from Singapore, transit is typically under 24 hours door-to-door via SingPost or DHL. Buyers in Hong Kong shipping boards for copy services can use same-day cross-border couriers, with packages reaching our Pudong lab before noon the following day.
For Middle Eastern clients, our Dubai-to-Shanghai PCB copy route runs 3-day express through Emirates SkyCargo. Southeast Asian buyers in Bangkok sending boards for duplication see 2-day transit via Thai Post EMS or DHL.
We also serve clients in South Asia and Latin America. Engineers in Mumbai seeking PCB reverse engineering typically receive files within 10 days of dispatch, accounting for 3-day inbound transit plus our standard processing window.
Intellectual Property & Legal Framework
Every project begins with a mutual NDA executed under PRC contract law (or under your jurisdiction’s law, if preferred). We require a signed declaration of ownership or authorized-agent status before work starts. Our facility is access-controlled: project files are siloed per client, and engineers working on your board cannot access other active projects.
We do not accept boards that are clearly marked as third-party proprietary without written authorization from the rights holder. This policy is non-negotiable and protects both parties. For questions about compliance, see our trust and IP compliance policies.

Request a feasibility reviewFrequently Asked Questions About PCB Copy in Shanghai
How long does PCB copy in Shanghai take for a 4-layer board?
A standard 4-layer board with fewer than 500 components typically takes 5–7 working days from the moment we receive it. Add 2–3 days for inbound shipping from most international origins. Rush processing can reduce engineering time to 3–4 days for a 50% surcharge.
Can you copy a board that is not working or partially damaged?
Yes. We regularly work with non-functional, burned, or water-damaged boards. Intact copper traces are imaged normally; missing or corroded sections are reconstructed from surrounding circuit context. We document every inferred connection so you can verify before fabrication.
What file formats do I receive after PCB copy?
The standard package includes RS-274X Gerber files, an Excel BOM with manufacturer part numbers, a schematic in PDF plus an editable source (Altium, KiCad, or Eagle — your choice), pick-and-place CSV data, and a stackup report. ODB++ output is available on request at no extra charge.
Is it legal to copy a PCB in Shanghai?
PCB reverse engineering for boards you own or are authorized to reproduce is legal under both PRC and most international jurisdictions. We require proof of ownership or written authorization before starting any project. Unauthorized duplication of third-party IP is something we decline.
