Main service

PCB copy, from one board to a fab-ready file set

Most projects start with a single physical board and no files anywhere in the company. This is the service that fixes that, and it is what we do most of.

PCB board cloning samples: copper layer, solder mask and populated boards
PCB copy · board cloning

1 to 32 layers, including the boards other shops send back

Blind and buried vias, laser microvia HDI, RF microstrip, ceramic and flex substrates, fine pitch BGA. Every net is checked electrically against your sample, then a prototype is built and tested before any file leaves the building.

  • You receiveGerber, BOM, PCB source, placement
  • ProofWorking prototype, flying probe report
  • 1-2 layer, from$150
  • 4-6 layer, from$280
  • 8-10 layer, from$550
  • 10+ layer, HDI, RF, from$1,100

Second service

IC unlock, IC crack and chip decipher

Protected MCU, ARM, CPLD and FPGA parts read out through software attack, fault injection, side channel analysis or invasive microprobing, whichever the die calls for. Our database covers 5000+ models.

  • 8051, STC, Holtek, from$220
  • STM32 F0 / F1 / F3, from$700
  • ARM, Renesas, Infineon, from$2,000
You receive: Bin + Hex file, 2 programmed chips

Third service

PCB reverse engineering

Schematic recovery for boards you need to change, not just repeat. Netlist extraction verified connection by connection, every part identified with a real manufacturer number, and editable source your own engineers can open.

  • Schematic + BOM, from$400
  • Prototype build and test, from$600
  • Typical lead time7-15 days
You receive: schematic, netlist, BOM with MPN, source files

Full price list
How a project runs

Four steps, and you can stop after any of them

  1. Free feasibility check

    Send photos of the board or the chip marking. Within 24 hours you know whether it can be done, how long, and what it costs.

  2. NDA, then ship the sample

    We sign first, you ship second. Courier details and our full registered address go to you in writing.

  3. Engineering and your test

    We copy the board, recover the schematic or read out the chip, then send samples. The balance is due after your own test passes.

  4. Files, and production if wanted

    Full file package delivered. SMT assembly, X-ray BGA inspection and flying probe testing are in house if you need boards built.

Where the risk sits

If we cannot do it, you pay nothing

Sending a board to a supplier on the other side of the world is a real risk. These five terms move most of it onto us, and they are in the quote you receive, not only on this page.

  • Feasibility assessed free, before you commit
  • 50% deposit, balance only after your test passes
  • Full refund if the sample boards or chips fail your test
  • NDA signed before anything ships
  • Your files are never reused, resold or shown

Before you send an enquiry

Five questions we answer every day

Gerber files ready for any fab, a BOM with real manufacturer part numbers, placement data, the PCB source file, and a prototype we have already built and tested against your sample. Boards from 1 to 32 layers, starting at $150.

A copy reproduces the board exactly as it is and is faster and cheaper. Reverse engineering recovers the schematic so you can change something, which is what you need when a part has gone obsolete. Tell us the goal and we will say which one actually fits.

Our unlock database covers 5000+ models, and 126 of them across 28 families are published on the chip list page. If yours is not listed it usually still works, we just have not published it. Send the marking and the check is free.

You pay nothing. The feasibility check costs nothing and any deposit is returned in full. We say so early rather than late.

We sign an NDA before you ship. Files are returned or deleted on request after delivery, and nothing goes into a portfolio without written permission.
