Consumer electronics PCB copy means taking a finished board — a speaker amp, a router, a handheld charger, a smart thermostat controller — and rebuilding the manufacturing data set from the physical hardware: Gerber layers, drill files, BOM, pick-and-place, and a schematic if you need one. You send the board, we scan and delaminate it, and you get files you can send to a fab and an assembler. Firmware is a separate question, and we’ll get to it below.
Most people who land here are in one of three spots: the original design files are gone, the CM disappeared, or a key part went end-of-life and nobody can find the source netlist to make a swap. All three are normal, and all three are solvable from a sample.
What consumer electronics boards do differently
Consumer hardware is built to a cost target, and that shows up in ways that change how a copy job runs. Boards are small, often 4-layer, and packed edge to edge because the enclosure was designed first. Trace and space frequently sit at or below 4 mil. You’ll see 0402 and 0201 passives, QFN and LGA packages with no visible leads, and 0.4 mm pitch BGAs on anything with a Wi-Fi SoC or an application processor.
You also see a lot of unmarked or house-marked silicon. Consumer OEMs sand off part numbers, use custom laser codes, or buy from a Chinese analog house that never published a datasheet in English. That’s the part of the job that eats hours — not the copper.
Two more things show up constantly on this category and almost nowhere else: rigid-flex tails going to a display or button panel, and single-sided phenolic boards inside cheap AC-powered products like fans, kettles, and LED bulbs. Those two extremes need completely different handling, and the price gap between them is large.
Where the RF sits
Any consumer board with a radio has a section where the copy has to be geometrically exact, not just electrically equivalent. Antenna traces, the matching network pads, the ground cutout under a chip antenna, the impedance-controlled feed line — those get copied to the micron rather than redrawn to a tidy grid. We measure dielectric thickness on the sectioned sample and check the calculated impedance against the stack-up before signing off, because a 2 mil dielectric error on a 50 Ω feed will show up as a range problem on the finished unit and nothing else.
How we actually take the board apart
Nothing about this is magic. It’s a sequence, and each step gets verified against the previous one.
- Intake and photography. Both sides at high resolution, plus close-ups of every marked component. This is the reference record if anything later gets damaged.
- X-ray. Buried vias, inner-layer via structures, and BGA ball counts get imaged before anything is removed. On HDI consumer boards this is where we find out whether there are microvias and stacked vias, which changes the fab spec.
- Component removal and identification. Parts come off with the reference designator logged. Unmarked ICs get curve-traced, pin-mapped, or opened up if the function can’t be inferred. Passives get measured, not guessed — the LCR meter reading and the package size go into the BOM together.
- Layer separation. The bare board is scanned, then ground down one layer at a time and rescanned. Each inner layer is imaged separately, which is why a 4-layer board takes meaningfully longer than a 2-layer one, and an 8-layer HDI board longer again.
- Vectorizing and stack-up reconstruction. Scans become real copper geometry. Drill sizes get measured. Dielectric thicknesses come off the cross-section. We build the file set to IPC-2221 clearance and IPC-6012 fabrication conventions so a fab can actually quote it without asking twenty questions.
- Netlist verification. The rebuilt netlist is compared point-to-point against the original board. This is the single most important check in the job — the continuity test either matches or it doesn’t.
- Prototype and functional check. We build a small run, assemble it, and power it up against the original as a reference. Consumer boards make this easy: you plug in, pair the app, run the motor, measure the output rail.
If you want the process explained in more detail across board types, our writeup on industrial control board duplication covers the same workflow on slower, higher-voltage hardware, where the tradeoffs are different.
What you send us, and what comes back
Getting a real quote takes about five minutes on your end. Send:
- Clear photos of both sides of the board, on a dark background, whole board in frame, in focus, no flash glare across the silkscreen.
- Board dimensions — length, width, and thickness if you can measure it.
- The main chip marking, typed out exactly as printed, including the line under the part number.
- One line on deliverables: Gerber only, Gerber + BOM, full schematic, or turnkey boards in hand.
- Quantity, if you want assembled units rather than just files.
Back within a day or so you get a feasibility read, a lead time, and a price. The feasibility answer is the important one — it tells you whether the unmarked parts on your board are identifiable and whether anything on it blocks the job.
The deliverable set is where consumer electronics PCB copy projects vary most:
| Tier | You receive | Good for |
|---|---|---|
| Files only | Gerber, drill, stack-up, netlist | Rebuilding an out-of-production board as-is |
| Files + BOM | Above, plus BOM with sourcing notes and pick-and-place | Handing the whole package to your own assembler |
| Full reverse engineering | Above, plus editable schematic and PCB source | Changing the design, swapping an EOL part, cost reduction |
| Turnkey | Assembled, tested boards | You need working hardware, not a data package |
Pick the schematic tier only if you plan to modify something. If you just need the same board built again, the Gerber and BOM package is faster and cheaper.
Where consumer boards get hard, and where we say no
This is the part competitor pages skip. Honest constraints:
Custom and house-marked ICs. If your board runs on an ASIC that one OEM had made for them, we can copy the footprint and the surrounding circuit, but nobody can buy the part. Copy is only useful there if you already have stock.
Potted and conformal-coated assemblies. Common in chargers and outdoor consumer gear. Removal is possible but the coating sometimes takes pads with it, and heavily potted urethane blocks can damage components on the way out. Two samples help a lot here.
Single samples of dense HDI. Layer separation is destructive. On a 0.4 mm pitch BGA board with stacked microvias, one board is enough to do the job but leaves no fallback if something tears. If you can spare two, send two.
Flex circuits with adhesiveless polyimide. Thin, delicate, and the copper is easy to lift. Doable, slower, priced accordingly.
Firmware. A copied board is dead hardware until code is loaded. If the MCU is locked and you don’t have the hex file, that’s a separate feasibility question entirely — an STM32 sitting at RDP Level 2, a fused MSP430 JTAG, or set lock bits on an AVR each behave differently. Some cases are routine, some are not, and we tell you which before you pay. Our page on appliance controller duplication deals with the same firmware-plus-board pairing on 8-bit parts.
One more limit that isn’t technical: we work on hardware you have the right to reproduce. Recovering your own lost design, keeping a discontinued product serviceable, migrating off an obsolete part, or doing failure analysis is what this service is for, and you’re responsible for holding those rights. Every project runs under NDA, and boards and files stay inside our lab.
What drives the price and the schedule
There’s no flat rate, and anyone quoting one before seeing photos is guessing. The variables that actually move the number:
- Layer count. Each inner layer is a separate imaging pass.
- Component count and package mix. Two hundred 0402s and six QFNs is more identification work than forty parts in SOIC.
- BGA presence. X-ray time, careful reball, and no visual access to the pads.
- Unmarked silicon. The single biggest wildcard on consumer hardware.
- Deliverable tier. A schematic costs more than Gerber because someone has to read every net and draw it as a circuit that makes sense.
- Firmware. Priced separately, per chip family.
- Board condition. Burned, corroded, or previously reworked samples add time.
On schedule: a small 2-layer board with marked parts is a matter of days. A dense 4- or 6-layer board with fine-pitch BGAs and a handful of mystery chips runs meaningfully longer, and the identification work — not the copper tracing — is usually what sets the date. Boards with an RF section add a verification cycle because we want measured performance on the prototype before we call it done. If you’re comparing categories, flight controller and drone board copy sits at the harder end of the same spectrum.
FAQ
Can you copy a consumer PCB if the part numbers are sanded off?
Usually, yes. We identify unmarked parts by pin mapping, curve tracing on the removed device, package and die size, and where the part sits in the circuit — a three-pin SOT-23 between a rail and a filter cap has a limited number of possibilities. Custom ASICs are the exception: we can copy the footprint, but you can’t buy the chip.
