Why BOM verification matters before production starts
In PCB assembly, BOM quality is not just an administrative task. A small mismatch between AVL data, CAD information, and the actual component set can create delays, rework, and costly clarification loops before the first board is built. This is exactly where the BOM Expert in PCB-Investigator adds value.
The plugin is designed for preparing and verifying the bill of materials for PCB assemblies. It imports AVL lists in multiple formats, including Excel, CSV, TXT, and XML, and compares part numbers against a parts library such as the EasyLogix Part Library, which is continuously updated and expanded.
Validate parts with real geometry, not assumptions
What makes the workflow especially practical is the graphical overlay of real part geometries onto the CAD components. That means you can check fit, position, and orientation directly in context. If needed, angle and position corrections can be defined right in the tool.
The BOM Expert also performs automatic pin analysis and reports mismatched parts reliably. When several alternatives are available in the AVL, you can choose the preferred option, for example based on supplier preference or specific procurement requirements.
The result is more than a clean BOM. It is a digital twin of the physical prototype that is ready for downstream use.
From BOM control to a richer digital twin
Beyond verification, the tool enriches CAD data with library properties and, where available, 3D step models. That creates a more realistic representation of the assembly that can be used for further analysis, simulations, and machine exports.
- Import AVL data from common engineering formats
- Match part numbers against a maintained library
- Overlay real geometries for visual verification
- Detect pin mismatches automatically
- Select alternatives and enrich data with properties and 3D models
If BOM accuracy is a priority in your workflow, BOM Expert is worth a closer look.
