PCB copy in Shenzhen puts your reverse-engineering project inside the world’s densest electronics supply chain. Our Futian-district lab receives your sample board — by hand-delivery, local courier, or international express — strips it down layer by layer, and returns a complete Gerber package, cross-referenced BOM, and optional netlist-verified schematic. Typical turnaround: 5–8 working days for boards up to 8 layers, with same-city prototype fabrication available within 48 hours of file sign-off.
Why Run a PCB Copy Project in Shenzhen?
Every other metro on earth adds transit time and supply-chain friction to a copy job. Shenzhen eliminates both. Component cross-referencing happens against live distributor stock in Huaqiangbei — the same district where our engineers source verification samples the same afternoon. Prototype boards come off the line at partner fabs in Baoan or Longhua, often before an overseas courier would even clear customs.
For clients already manufacturing in the Pearl River Delta, a Shenzhen-based PCB copy service means zero import duties on sample boards, Mandarin-native communication with your CM, and the ability to walk into our lab for a face-to-face review of the deliverables.
What You Receive from a Shenzhen PCB Copy
| Deliverable | Format | Detail Level |
|---|---|---|
| Gerber file set | RS-274X / Gerber X2 | All copper layers, solder mask, silkscreen, drill files, board outline |
| Bill of Materials | Excel / CSV | Manufacturer P/N, package, value, designator, verified availability |
| Schematic (optional) | Altium / KiCad / OrCAD PDF | Netlist-verified, hierarchical sheets for designs > 200 nets |
| Centroid / pick-and-place | CSV | X-Y coordinates, rotation, reference designator |
| Stackup report | Cross-section micrograph, dielectric thickness, copper weight per layer |
Every file set is DRC-checked against IPC-2221B before release. If we spot impedance-critical traces (differential pairs on USB, LVDS, Ethernet), we include a controlled-impedance note with target Ω and calculated trace/space dimensions so your fab house can match the original stackup.
How the Process Works — Step by Step
1. Ship or Drop Off Your Sample
Local clients hand-deliver to our Futian office. International clients ship via DHL or FedEx; we supply a Chinese import address with HS code guidance so the board clears Shenzhen customs without delay. Two boards are ideal — one for non-destructive scanning, one for cross-section and delayering.
2. Intake Assessment (Day 0–1)
We photograph the board at 20 MP resolution, run an initial component count, and identify any BGA, QFN, or shielded-can ICs that will need X-ray imaging. You receive a complexity grade (A–D) and a firm quote within one business day.
3. Layer Imaging & Extraction (Day 1–5)
Outer layers are captured with a 2400 DPI optical scanner. Inner layers are exposed through controlled chemical etching, then re-scanned. Our operators align each layer image to fiducials within ±0.5 mil, then vectorize copper features into Gerber data. For boards with 10+ layers or HDI microvias, we use a micro-section under 500× magnification to map via stacks and confirm laminate thicknesses.
4. BOM Verification & Schematic Recovery (Day 3–7)
Component markings are decoded against manufacturer databases. When markings are sanded or encrypted — common on power management ICs and Chinese-domestic MCUs — we cross-reference package, pin count, and circuit context to narrow the part. Schematic recovery runs in parallel: our engineers trace connectivity from the Gerber netlist, grouping by functional block (power, digital core, analog front-end, I/O).
5. DRC, Review & Delivery (Day 5–8)
Final Gerber files pass automated DRC plus a manual spot-check against the physical board. We deliver via encrypted cloud link or USB drive, under NDA. Clients in Shenzhen can pick up a USB in person and review files on-screen with our engineer before leaving.
Shenzhen-Specific Advantages for PCB Copy
- Same-day component sourcing: Huaqiangbei and online platforms like LCSC let us verify or substitute parts within hours, not days.
- Prototype fab in 24–48 hours: Partner PCB factories in Baoan accept Gerber data directly from our output, with 2-layer boards shipping same-day for urgent jobs.
- Assembly line next door: If you need cloned boards assembled, SMT lines in Longhua or Songgang can run your first batch while you are still in the city.
- No export/import on samples: Boards already in mainland China skip international shipping entirely, saving 3–5 days and ¥200–¥800 in courier fees.
Capability Limits — What We Handle and What Gets Complex
| Parameter | Standard Range | Extended (quote required) |
|---|---|---|
| Layer count | 1–8 layers | 10–24 layers |
| Minimum trace/space | 4 / 4 mil (0.1 mm) | 3 / 3 mil (HDI) |
| Board size | Up to 400 × 500 mm | Larger panels on request |
| Via types | Through-hole, blind | Buried, stacked micro-via, via-in-pad |
| Substrate | FR-4, CEM-3 | Rogers, polyimide flex, aluminum-core |
| Turnaround | 5–8 working days | 3 days (rush) / 12+ days (24-layer) |
Flex-rigid boards and metal-core substrates require modified etching chemistry and longer imaging cycles. We quote these individually after intake assessment. Boards with conformal coating or potting compound need an additional 1–2 days for safe removal.
Pricing Signals for Shenzhen PCB Copy
Exact pricing depends on layer count, component density, and whether schematic recovery is included. As a reference range for budgeting:
- 2-layer, ≤ 100 components: ¥1,500–¥3,000 (≈ $200–$420)
- 4-layer, 200–400 components: ¥4,000–¥8,000 (≈ $550–$1,100)
- 8-layer with schematic: ¥10,000–¥20,000 (≈ $1,400–$2,800)
- Rush surcharge (3-day): +40–60%
Walk-in clients in Shenzhen can request a free visual assessment before committing. Remote clients receive a binding quote after we inspect high-resolution photos of both sides of the board.
Who Uses PCB Copy in Shenzhen?
Hardware startups iterating on a contract manufacturer’s reference design. Repair depots that need spare-board fabrication data for end-of-life industrial controllers. OEMs consolidating multi-vendor designs into a single in-house platform. R&D teams benchmarking a competitor’s RF layout or power-supply topology — within the bounds of their own IP rights.
International clients who need the same service closer to home can explore our PCB copy workflow for Dubai, our Singapore office process, or board copy services in Mumbai. Clients in mainland China outside Guangdong may also consider our Shanghai-based PCB copy lab for shorter domestic shipping.
Shipping a Board to Shenzhen from Overseas
Most international shipments arrive within 2–3 business days via DHL Express or FedEx International Priority. Declare the board as “printed circuit board sample, no commercial value” with HS code 8534.00. Chinese customs rarely holds low-value PCB samples, but we provide a letter of invitation if your courier requests one.
Clients in Hong Kong shipping to Shenzhen benefit from same-day cross-border courier services — boards dropped at a Kowloon collection point reach our Futian lab within four hours.
Quality Assurance & Confidentiality
Every project is covered by a bilateral NDA signed before the sample ships. We store files on air-gapped workstations during the active project and transfer final deliverables via AES-256 encrypted links. Physical samples are returned or destroyed per your instruction after file acceptance.
Our engineers follow IPC-2581 data-exchange standards where the client’s downstream toolchain supports it, ensuring lossless handoff to any major EDA platform or fab house.
Can I visit the Shenzhen lab in person to watch the PCB copy process?
Yes. Our Futian office accepts scheduled visits on business days. You can observe layer imaging, review Gerber overlays on-screen with the assigned engineer, and collect deliverables on a USB drive the same day files are finalized. Contact us 48 hours in advance to arrange access.
How many sample boards should I send for a PCB copy job?
Two identical boards are ideal. One stays intact for reference and dimensional checks; the second is delayered to expose inner copper. If only one board is available, we can still complete the job — we photograph and scan all outer features before any destructive steps — but turnaround may add 1–2 days for extra caution during etching.
What if some component markings are sanded off or unreadable?
We use a combination of X-ray imaging (to see die size and bond wires inside the package), circuit-context analysis, and our internal database of Chinese-domestic part markings. In roughly 90% of cases we identify the exact part number; for the remainder, we provide a functional-equivalent recommendation with matching pinout and electrical specs.
Is PCB copy in Shenzhen legal?
Reverse engineering a PCB you own — for repair, interoperability, or authorized re-manufacture — is legal in most jurisdictions. We require proof of board ownership or written authorization from the IP holder before starting work. All projects are executed under NDA.
Can you also fabricate and assemble cloned boards after the copy?
Yes. Because we operate inside Shenzhen’s manufacturing ecosystem, we hand off verified Gerber and BOM data directly to partner PCB fabs and SMT lines. First-article boards can be ready within 5–7 days after file sign-off, with full electrical testing included.
