**How to ensure a clean BOM:**

- Verify BOM information with component datasheets to validate accuracy. Try the [BOM Compare Tool](https://www.protoexpress.com/tools/bom-compare-tool/) to compare two BOM files.
- Validate BOM entries with the reference designators in the design files to ensure consistency and prevent duplication.
- Double-check vendor details, part numbers, and lead times to manage the assembly errors.
- Estimate component quantities accurately as per the assembly requirements.
- Regularly review and update the BOM to identify obsolete components and restock them with suitable alternatives.
- Implement a checklist to cross-check BOM against the design files.
