Library Health Checklist
Use this checklist to assess the current state of your library against the practices in this guide. It is not intended to be
completed in one pass. Use it to identify the highest-priority gaps and sequence the work.
Schema and Data Completeness
f
All component records include lifecycle status from a current, authoritative source
f
Lifecycle risk rating (Low / Medium / High) is populated for all parts
f
Predicted years to end of life is recorded for all active parts
f
Date of last lifecycle review is stored separately from the date the part was added
f
Compliance fields (RoHS, REACH, conflict minerals) are required at part creation, not optional
f
Counterfeit risk rating is populated for all parts, sourced from an aggregated database
f
Lead time fields include a date of last review, not just a static value
f
Approved alternates are documented with independent supply chain verification for critical components
f
Multi-sourcing options are recorded in the library and flow through to the BOM
f
Part numbering follows a standardized convention with automatic incrementing
CAD Model Quality
f
All footprints have been verified against the manufacturer recommended land pattern per IPC-7351 or any internal
standards that would supersede the IPC spec
f
Footprint verification accounts for the intended assembly process (reflow, wave, or hand soldering)
f
All schematic symbols have been verified against the manufacturer datasheet
f
3D models are associated where required for mechanical clearance review
f
Date of last CAD model verification is recorded for each part
f
Pre-built models sourced externally have been verified before being added to the library
f
Schematic symbols, PCB footprints, and 3D models are cross-validated against one another to ensure mechanical,
electrical, and pin-mapping consistency across the entire component definition
