Trusted By
Well Done Technology focuses on PCB reverse engineering, PCB clone, and IC unlock. Our technical team of more than 40 people includes senior engineers with rich experience. Founded in 2008, we have completed over 1,000 PCB engineering projects for clients worldwide, including North America, Europe, and Southeast Asia.
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.
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 |
Looking for more service about PCB engineering? You can benefit from our wide range of services as below. And our experts will ensure no delays due to quality or errors while working on your project.
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.
Due to the growing application of low-impedance circuits, low-impedance modeling has become an important aspect of circuit design. If you have mpedance-controlled requirements, we can help you for controlled impedance modeling.
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.
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.
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. Some of the most popular programs include: Gerbv, Adobe Illustrator, CorelDRAW.
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.

If you want to create a KiCad design from text, start with structured parts, named nets, power assumptions, and ERC checks so the generated schematic stays editable and reviewable.
Moving a legacy Protel design into Altium Designer is not just a file-open task. This guide covers libraries, rules, polygons, outputs, and verification steps that keep old boards manufacturable after migration.
Choosing the smallest N-channel MOSFET through hole package means balancing gate drive, fault energy, thermal margin, pinout, and rework access on the real PCB.
Learn how to fix KiCad silkscreen-to-mask clearance warnings without hiding real DFM issues. Start at the footprint, verify Gerbers, and protect assembly-critical legend.
Please provide high-definition pictures of both sides of the circuit board, the number of layers, the size and details of any encryption chips.
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.
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.
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.
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.
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).
Absolutely. We can redesign your PCB such as upgrading components for availability/cost, reducing board size, improving thermal performance, or enhancing signal integrity.
Our engineers specialize in Altium Designer, KiCad and Cadence OrCAD. We provide files in industry-standard formats (Gerber, ODB++, BOM, schematic PDFs).
We offer rapid prototyping and test (AOI & ICT). Material options: FR-4, Rogers, aluminum-based PCBs, and flexible circuits.
We provide services for medical devices, industrial electronics, consumer electronics, IoT & embedded systems, etc.
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.
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.
