If an existing/shared footprint exists, it is used
If a common footprint is used, verify fitment against the datasheet (basically confirm the package fits the footprint we have, rather than the datasheet footprint exactly matching our footprint)
Footprint matches datasheet
Verify pin mapping
Verify dimensions
Verify units
Verify hole size
Layers are setup correctly: https://nerdocs.atlassian.net/l/cp/khnHr5Zw
Confirm footprint name makes sense and is stored in the right folder (no randomly generated names!)

These should be covered by the above, but please double check these as they’re what most commonly screw us up! |
Rotated/flipped MOSFETs and diodes
Footprint in datasheet is looking from the bottom and we enter it as looking from the top (causing flipped footprint)
