Schematic and BOM Extraction from an Industrial PCB

Extract a schematic and a bill of materials from the board that is actually in the machine.

Schematic and BOM extraction gives your maintenance team two documents they can work from: a circuit diagram and a parts list. We read reference designators, package markings, and the copper that ties them together.

The result is meant for repair planning and for a later redesign. Where a marking is ambiguous, the BOM says so instead of guessing a convenient part.

Where this service fits

• Technicians can replace a failed module only if they know the installed part.
• A redesign vendor asked for a schematic before estimating firmware or power changes.
• The BOM in the storeroom does not match the board revision on the line.
• A shutdown window is coming and the parts list must be ordered early.

What you receive

• Schematic sheets organized by power, control, and I/O
• BOM with designator, marking, package, and quantity
• A list of parts that need in-circuit measurement
• Cross-highlight notes between schematic and board photos

How the work proceeds

1. Receive photos or the sample under the authorization checkbox.
2. Index every designator and readable marking.
3. Trace nets into schematic symbols.
4. Issue the BOM and the open-item list together.
