PCB copy, reverse engineering & IC unlock.
Keep proven electronics in service.
Recover the board files, circuit documentation and firmware your next step depends on. We help maintenance teams, OEMs and repair businesses move from a physical sample to a defined, tested result.

Start with the result you need.
Manufacturing files, readable circuit documentation and firmware solve different problems. Choose a starting point below; we can combine the work when your replacement needs more than one service.
PCB copy & cloning
Rebuild fabrication and assembly data from your sample. Define the Gerber, BOM, layout files and prototype checks needed to produce a replacement.
Outcome: a manufacturing package
Explore PCB copy →PCB reverse engineering
Recover a readable schematic, verified connections and component information so your engineers can troubleshoot, document or plan a redesign.
Outcome: usable design knowledge
Explore reverse engineering →IC unlock & IC crack
Assess a protected chip for firmware recovery. Confirm the exact part, required program files and programmed samples for your equipment tests.
Outcome: an agreed firmware package
Explore IC unlock →Photos, partial files or a physical board?
Choose the next useful step before requesting a complete recovery project.
With photos, begin with a sample and feasibility review. With partial files, identify what is verified and what is missing. With a usable design package, confirm the remaining manufacturing or validation work.
Real boards. Specific outcomes.
These published examples show what was recovered and how the customer used it. The work and timing for your board are confirmed after its own review.

Keep a packaging line supplied with spares.
Firmware recovery and PCB copy restored a replacement path after support for the original controller ended.

A result you can check.
Start with photographs and requirements. The initial review is free, and the agreed work is recorded before your project begins.
How a project runsReview the sample and outcome
Tell us what has failed, which files are missing and what success means for your equipment.
Agree confidentiality, scope and handling
Arrange the NDA, file list, sample requirements, written quote and acceptance tests. Wait for shipping instructions.
Recover, verify and hand over
Review the agreed files or samples against the test criteria. Optional prototype and production work is defined in the quote.
Confidence comes from clear commitments.
Based in Bao'An, Shenzhen, China. Serving customers internationally since 2010, with Judy as your project contact.
Confidentiality before files
Arrange an NDA before sending sensitive design information. Customer files are not reused, resold or shown.
Defined commercial terms
50% deposit, balance after your test passes, and a full refund if the agreed sample boards or chips fail your test. Record the scope and acceptance conditions in the quote.
Deliverables you can use
Specify the file formats and software versions your engineers or manufacturer need. Hardware and firmware requirements are reviewed together when necessary.
Transparent starting prices
Use the published prices for an initial budget, then request a quote for your exact board or chip.
View prices and lead times →Check the published model list.
A listed family is a starting point. The exact marking, revision and sample condition still need review.
Explore approaches to board recovery.
Before defining your project, explore the PCB cloning process and compare PCB reverse engineering methods. Use these references alongside a clear list of the files, sample handling and acceptance checks your own project requires.

PCB Repair vs Replacement: A Guide for Legacy Equipment
A failed circuit board creates two decisions: how to restore the machine now, and how to support it when the next board fails. Compare the options before committing to a repair or a replacement project.
BIN vs HEX Firmware Files: What Your Replacement MCU Needs
A firmware file is only useful when the destination, memory map and programming requirements are understood. Learn what BIN and Intel HEX describe, and what else a replacement microcontroller may need.
PCB Clone Not Working? Check Hardware, Firmware and Test Conditions
A board that looks identical can behave differently. Organize the evidence before changing parts or rewriting firmware, so the next engineering step addresses the actual mismatch.
A few practical answers.
Which PCB-Copy service should I choose?
Choose PCB copy when you need manufacturing files and replacement boards. Choose PCB reverse engineering when you need a readable schematic and circuit information for analysis or redesign. Choose IC unlock when missing firmware prevents a compatible replacement from operating. A single project can combine these services; explain the required outcome and we will review the scope.
What should I send for an initial review?
Start with clear photographs of both sides of the board, approximate dimensions, sample condition and the result you need. For firmware work, include the complete chip marking. Tell us if this is your only working sample. Contact Judy before sharing confidential files if you need an NDA, and wait for confirmed shipping instructions before sending hardware.
How are price, payment and acceptance agreed?
The initial feasibility review is free. The written quote defines the scope, deliverables, handling plan, timing and acceptance tests. Our terms are a 50% deposit, the balance after your test passes, and a full refund if the agreed sample boards or chips fail your test. Confirm the project-specific scope and test conditions before placing the order.
Where is PCB-Copy based, and can overseas customers enquire?
PCB-Copy is based in Bao'An, Shenzhen, China and works with customers internationally. Judy is the project contact at Judy@4PCBA.com. Initial communication can begin with photographs and requirements; the shipping address, sample handling and return arrangements are confirmed in writing before dispatch.
Tell us what you need to bring back.
