Schematic and BOM reconstruction
Documentation recovered from a physical board: a readable schematic and a bill of materials with part numbers wherever they can be established. It's the core of every reverse engineering project, and it can be ordered on its own when you need to understand, repair, or support a board rather than rebuild it.
- Part of
- Steps 2–4 of PCB reverse engineering.
- Start with
- Photos of both sides for the assessment, then the board itself. Any partial documentation you have.
- You receive
- A schematic, a BOM with availability notes, and — if scoped — a component placement reference. Formats agreed in the quotation.
From a bare board to documents you can read
- 01
Component identification
Each part identified from markings, package, and measurement where needed. Parts that can't be identified with confidence are listed as such, with what it would take to resolve them.
- 02
Schematic reconstruction
Connectivity traced from the board and drawn as a schematic organized by function, with reference designators that match the board — so a technician can follow it with the board in hand.
- 03
BOM with availability
Reference designators, values, packages, and manufacturer part numbers where established — each line checked for current availability, so obsolete parts are flagged in the document, not discovered at a distributor.
- 04
Documentation package
Delivered in the formats agreed in the quotation. The design-source format is confirmed for your board before work starts.
Reasons to stop at the documents
- A repair or maintenance team needs to troubleshoot a board to component level.
- You're deciding whether cloning is worth it and want to know what's on the board first.
- You need a design record for continuity, compliance, or a supplier transition.
- You plan a redesign and need an accurate starting point rather than a guess.
Photos first. The board when scope is agreed.
Start the assessment with "Documentation" as the outcome. The response tells you what looks recoverable from the photos and what the documentation package would include for your board.
