PCB Reverse Engineering Service Capabilities
Our PCB reverse engineering service helps recover manufacturable design data from legacy boards, discontinued electronics, damaged samples, or products without original CAD files. The goal is not only to copy board geometry, but also to rebuild useful engineering outputs such as schematic diagrams, BOM information, Gerber files, netlists, and PCB layout files for repair, redesign, or controlled production.
Quality checks for reverse engineered PCB files: before delivery, files should be checked against the physical board, component orientation, net continuity, design rules, drill data, and manufacturing constraints. Common references include IPC-A-600 for board acceptability, IPC-6012 for rigid PCB performance, and IPC-2221/IPC-2222 for general design guidance.

What We Need Before Quoting A PCB Reverse Engineering Project
For a reliable quote, please share board photos, board dimensions, layer count if known, component-side images, any available firmware or part markings, and the expected output files. For multilayer PCBs, destructive layer-by-layer analysis may be required when internal traces, blind vias, buried vias, or controlled impedance structures cannot be confirmed from the outside.
| Input from customer | Engineering review | Possible deliverables |
|---|---|---|
| Physical PCB sample | Layer count, stackup, trace routing, component placement | PCB layout, Gerber, drill file, netlist |
| Board photos and markings | IC identification, passive values, connector mapping | BOM, schematic notes, replacement suggestions |
| Known failure symptoms | Power, signal, and test-point troubleshooting | Repair guidance, test report, redesign advice |
Value-Added Services
Looking for additional PCB engineering services? Choose from the options below. Our experts help prevent delays caused by quality issues or design errors while working on your project.
PCB Stackup Design
When designing a PCB stackup, we can help our customers guide, create or verify the stackup. They are suitable for all impedance control requirements for single-ended, differential pair, coplanar waveguide and other technologies.
Controlled Impedance PCB
Due to the growing application of low-impedance circuits, low-impedance modeling has become an important aspect of circuit design. If you have impedance-controlled requirements, we can help you for controlled impedance modeling.
Design Rule Checking
Design Rule Check verifies trace and space, open or shorted nets, aspect ratio, and other parameters of your design. It’s used to prevent potential errors in the production process by identifying them in the design phase.
PCB Surface Finish
There are numerous printed circuit board surface finishes, including ENIG, HASL (Tin-lead or lead-free), Immersion Silver, ENEPIG, and so forth. Well Done has rich experience assisting customers in choosing the correct surface finish solution.
DXF To Gerber Files
Gerber files are generally more accurate than DXF files since they are meant for machine-readable output. You can use a variety of software programs to convert DXF to Gerbers.
High Density Surface Mount
High Density Surface Mount Technology (HD-SMT) uses very densely packed arrays of small, closely spaced pads. This enables significantly higher component density than traditional surface-mount.

Testimonials From Clients
What impressed me the most about Well Done is how efficient their work was. Everything from quotation, to PCB manufacturing and assembly, to component sourcing was done under one roof with them! Their prices for small features are reasonable as well. Well Done makes good job in PCB design, IC decryption projects. And they has been working together on many high-volume prototyping tasks too.
OLIVERR&D Engineer, Industrial Electronics, North America
OLIVERFirst off, I found the staff of Well Done to be professional and eager to help. They were more than happy to answer any questions that I had concerning their PCB making service before placing my order, which made me feel confident about what they could do for me. The quality of the boards was excellent as well – probably one of the best boards that I have received after getting them from a number of different suppliers in recent years!
ETHANI am trying to find a good PCB Assembly manufacturer that can produce my device, but it is a very sensitive item and any issues with the components could cause problems. However, after using Well Done’s rigid PCBs, I’m extremely satisfied. Would recommend Well Done for PCB manufacture services with no reservations whatsoever! My next project will definitely involve going back-and this time because it’s cheaper too!

FAQ
What do you need for fully reverse engineering a PCB board?
Please provide high-definition pictures of both sides of the circuit board, the number of layers, the size and details of any encryption chips.
Can you reverse engineer PCBs with damaged or missing components?
For damaged circuit boards where the original manufacturer has discontinued production, we assist in reverse engineering the board through methods such as comparing manufacturer data sheets, circuit logic analysis, and X-ray imaging technology. However, we cannot guarantee 100% consistency with the original board.
Do you provide software reverse engineering?
Yes, we provide software reverse research and development services: software program code extraction, software rewriting, software secondary development, software disassembly, software system modification and upgrade, etc.
Which types of integrated circuits (ICs) can your team unlock or decrypt?
We can do IC reverse engineering or decryption for STMicroelectronics, Xilinx, Altera, Lattice, Atmel, Microchip, Actel and more. You can find more details at Supportable IC Series & Models.
Can you make the PCB clone that are 100% same as the original board?
Yes, our self-developed PCB copy board software can truly achieve 100% cloning without any mistakes. We can send these electronic files to you: standardized PCB files, schematic diagrams SCH and BOM and other materials.
What is the turnaround time for a typical PCB cloning project?
In generally, it’ll takes 5–7 business days for single/Layer boards, 10–15 business days for Multi-Layer (2–16 layers) boards, and 15–20 business days for high-density/advanced tech (HDI, Flex PCBs).
Can you modify or optimize the design during reverse engineering?
Absolutely. We can redesign your PCB such as upgrading components for availability/cost, reducing board size, improving thermal performance, or enhancing signal integrity.
What software tools do you use for PCB design and layout?
Our engineers specialize in Altium Designer, KiCad and Cadence OrCAD. We provide files in industry-standard formats (Gerber, ODB++, BOM, schematic PDFs).
Do you provide prototyping services for clone and reverse engineer?
We offer rapid prototyping and test (AOI & ICT). Material options: FR-4, Rogers, aluminum-based PCBs, and flexible circuits.
What industries do your services cater to most frequently?
We provide services for medical devices, industrial electronics, consumer electronics, IoT & embedded systems, etc.
How much does a PCB reverse engineering service cost?
The cost depends on board size, layer count, component density, via structure, IC marking difficulty, and whether schematic recovery or only PCB layout recovery is required. A simple two-layer board is usually much faster than a dense multilayer industrial control board.
Can you reverse engineer multilayer PCB boards?
Yes. Multilayer PCB reverse engineering may require X-ray inspection, layer sanding, high-resolution imaging, and repeated net verification. If the board contains controlled impedance or high-speed signals, stackup and material assumptions should be reviewed carefully before fabrication.
