Expert Lighting PCB Copy for LED Drivers, Luminaires, and Smart Controls
A lighting PCB copy reproduces the complete design data—Gerber files, bill of materials, and schematic—from an existing LED driver, luminaire control board, or smart-lighting module. Our engineers handle aluminum-core (MCPCB), FR-4, and rigid-flex substrates commonly found in commercial and industrial lighting products, delivering verified output files in 5–8 working days under a project-specific NDA.
Why Lighting Boards Are Different from General Electronics
Lighting PCBs sit at the intersection of thermal management, high-current paths, and increasingly dense digital control. That combination creates reverse-engineering challenges you won’t encounter on a typical consumer board.
Aluminum-Core and Metal-Core Substrates
Most high-power LED boards use 1.0–3.0 mm aluminum-core laminates with dielectric layers rated between 1.0 and 8.0 W/m·K. During a lighting PCB copy, we measure dielectric thickness to ±0.05 mm and thermal conductivity class, because substituting a lower-grade laminate will shift junction temperatures and shorten LED life. We document the exact substrate specification so your fabricator can match it.
High-Current Traces and Copper Weight
LED driver boards often carry 2 oz or 3 oz copper (70–105 µm) on power planes, while signal layers stay at 1 oz. Our cross-sectioning step verifies copper weight per layer rather than assuming uniform thickness—a common shortcut that leads to thermal hotspots in reproduction runs.
Constant-Current Driver ICs and Dimming Protocols
Boards may include DALI, 0–10 V, PWM, or Zigbee/BLE dimming interfaces alongside constant-current regulators. We identify every IC—down to proprietary driver chips from Meanwell, Inventronics, or Philips Xitanium modules—and list pin-compatible alternatives where the original part has gone end-of-life.
What Does a Lighting PCB Copy Project Deliver?
| Deliverable | Format | Detail Level |
|---|---|---|
| Gerber / ODB++ files | RS-274X / ODB++ | All layers, drill files, solder mask, silkscreen |
| Bill of Materials | Excel / CSV | MPN, value, package, manufacturer, alternates |
| Schematic | PDF + native (Altium / KiCad on request) | Netlist-verified against physical board |
| Stackup report | Layer count, copper weights, dielectric type & thickness | |
| Component placement | Pick-and-place CSV / centroid file | X-Y coordinates, rotation, reference designator |
Every file set goes through a design-rule check (DRC) and a netlist comparison before release. If we find discrepancies—lifted pads, reworked traces, or component substitutions on your sample—we flag them in a deviation report so you can decide whether to replicate or correct.
Lighting PCB Copy Process: Step by Step
- Sample intake & NDA execution. You ship 1–2 working samples. We countersign an NDA before any board leaves its packaging.
- High-resolution imaging. Boards are scanned at 2400 DPI minimum. Aluminum-core boards receive additional IR imaging to map thermal via arrays hidden under LED pads.
- De-layering (multilayer boards). For 4+ layer FR-4 or hybrid builds, we micro-section to expose inner copper and measure trace/space to ±0.5 mil (±12.7 µm).
- Schematic extraction. Component values are verified with LCR meters and curve tracers. ICs are identified by markings, die inspection if markings are sanded, and functional testing.
- File generation & DRC. Gerbers are generated, DRC’d against IPC-2221B Class 2 (or Class 3 if specified), and netlist-compared to the schematic.
- Review & delivery. You receive a review package; we incorporate feedback within one revision cycle at no extra charge.
Common Lighting Board Types We Clone
| Board Type | Typical Layers | Substrate | Key Challenge |
|---|---|---|---|
| LED module (COB / SMD array) | 1–2 | Aluminum MCPCB | Thermal pad geometry, dielectric spec |
| Constant-current LED driver | 2–4 | FR-4, 2 oz Cu | High-voltage creepage, EMI filter layout |
| Smart lighting controller (DALI/Zigbee) | 4–6 | FR-4 | RF antenna matching, encrypted MCU |
| Emergency lighting inverter | 2 | FR-4 | Battery charge circuit, UL 924 compliance markings |
| Horticultural LED panel | 2–4 | Aluminum + FR-4 hybrid | Multi-channel current control, IP-rated connector footprints |
| Outdoor street-light driver | 2–4 | FR-4, conformal coated | Surge protection (10 kV / 10 kA per IEC 61547), coating removal |
Conformal coating—common on outdoor and industrial luminaire boards—adds an extra step. We chemically or mechanically strip the coating to access component markings without damaging solder joints, then document the coating type (acrylic, silicone, or polyurethane) so it can be reapplied after assembly.
What Can Go Wrong—and How We Handle It
Sanded or re-marked ICs. Budget LED drivers from some Asian OEMs deliberately obscure driver IC markings. We use die-level inspection and functional bench testing to identify the silicon, though in roughly 5–8 % of cases a proprietary ASIC cannot be sourced—at which point we propose a pin-compatible redesign rather than leaving you stuck.
Obsolete LEDs. Mid-power LEDs (e.g., Samsung LM561C, Cree XP-G2) cycle through revisions. We match the LED footprint and electrical spec, then recommend current-production equivalents with comparable lumen output and CRI.
Potted modules. Some LED drivers are fully potted in epoxy or silicone. De-potting is possible but adds 2–3 working days and carries a small risk of trace damage on very thin (0.8 mm) substrates. We assess feasibility before quoting.
Who Needs a Lighting PCB Copy?
- Luminaire manufacturers whose original board supplier has shut down or raised MOQs beyond what’s viable.
- Facility managers maintaining large-scale commercial lighting installations with discontinued driver boards.
- Lighting designers who need to second-source a proven driver design for a new housing or optic.
- Contract manufacturers tasked with reproducing a legacy fixture where design files were never transferred.
If your lighting project involves boards from adjacent power-electronics domains, we handle those too. Our team regularly works on solar inverter board cloning and UPS system PCB reproduction, which share similar high-voltage design constraints.
Turnaround and Pricing Signals
Standard lighting PCB copy turnaround is 5–8 working days for 1–2 layer aluminum-core boards and 8–12 working days for 4–6 layer FR-4 driver boards with schematic extraction. Rush service (3 working days for simple MCPCBs) is available at a 40 % surcharge.
Pricing depends on layer count, board area, and component density. As a rough guide:
- Single-layer MCPCB LED module (≤ 100 × 100 mm): starts around $280–$450
- 2-layer LED driver with BOM + schematic: $500–$900
- 4-layer smart lighting controller with BOM + schematic: $1,200–$2,000
These are starting ranges. Potted boards, conformal-coated boards, and boards requiring IC identification by die inspection are quoted individually after a feasibility review.
NDA and IP Protection
Every lighting PCB copy engagement begins with a mutual NDA. Your sample boards are stored in a restricted-access area, tracked by serial number, and returned or securely destroyed at project close. We do not retain production rights, and all generated files are your exclusive property. For details on our confidentiality framework, review our processes alongside related projects like test and measurement board cloning where similar IP sensitivity applies.

Check feasibility for your project
Send the chip marking or board details and tell us what you need to recover. Add clear photos if available.
Request a feasibility reviewCan you copy an aluminum-core (MCPCB) LED board?
Yes. We handle 1–3 mm aluminum-core MCPCBs with dielectric layers up to 8 W/m·K. We measure dielectric thickness and thermal class so your fabricator can source an equivalent laminate. Single-layer MCPCBs typically complete in 5 working days.
What if the LED driver IC markings are sanded off?
Our engineers perform die-level inspection and functional bench testing to identify the silicon. In about 5–8 % of cases the IC is a proprietary ASIC that cannot be sourced; we then propose a pin-compatible redesign using an available part.
Do you handle potted or conformal-coated lighting boards?
We do. Conformal coating is chemically stripped without damaging solder joints, and the coating type is documented. Fully potted modules require 2–3 extra working days for de-potting, with a small risk of trace damage on substrates thinner than 0.8 mm—assessed before quoting.
Is lighting PCB copy legal?
Reverse engineering for maintenance, second-sourcing your own product, or recovering lost design data is legal in most jurisdictions. We require proof of board ownership or authorized access and execute an NDA on every project. We do not assist with copying third-party patented designs without authorization.
How accurate are the reproduced Gerber files?
Trace and space accuracy is ±0.5 mil (±12.7 µm). Drill locations are verified against a 2400 DPI scan. Every file set passes a DRC and netlist comparison before delivery, and one revision cycle is included at no extra charge.
