Recover the engineering behind your circuit board.
PCB reverse engineering, schematic recovery and bill-of-materials documentation, informed by experience across more than 100 boards.
When the board exists but the documentation does not
We help teams reconstruct circuit information from existing PCBs and organise it into useful engineering documentation. Work can support maintenance, component identification and assessment of redesign options.
Define the required deliverables
- Schematic reconstruction for the agreed circuit scope.
- Component identification and bill-of-materials preparation.
- Identification of uncertain or inaccessible details.
- Engineering review of recovered information.
What affects the assessment?
Provide clear board photographs, dimensions, both-side access, known functions and any existing part numbers or documents. Physical samples may be needed. Multilayer interconnections, erased markings and programmable components can limit what can be recovered.
Firmware extraction and functional redesign are separate scope questions; schematic recovery alone does not guarantee those outputs.

What clients ask before starting
What do you deliver when a board is reverse engineered?
A typical package is a readable schematic, a bill of materials with the components we were able to identify, notes on the board stack-up, connectors and test points, and an explicit list of anything that could not be confirmed. The exact deliverables are agreed with you before the work starts.
Can you work from a board with no documentation at all?
Yes. That is the usual starting point. We work from the physical board, the components on it and the behaviour of the circuit rather than from existing design files.
What happens when a component is unmarked or obsolete?
Where a part has been sanded, relabelled or discontinued, we identify it from its package, pinout and behaviour in the circuit where that is possible. If a part cannot be confirmed, it is recorded as unidentified rather than guessed, and we set out candidate replacements for you to evaluate.
Do you need the physical board?
Access to a physical sample gives the most reliable result, because layer-by-layer inspection and measurement are usually needed. High-resolution photographs and scans can support the work but rarely replace a sample.
What do you need from us before starting?
A description of what the board does or should do, any partial documentation you already hold, and confirmation that you have the right to have the board examined.
