Key

  • This line was added.
  • This line was removed.
  • Formatting was changed.

...

  • If a generic/common symbol is available, it is used

    • Resistor, fuse, capacitor, etc

  • Symbol matches datasheet

    • Pin numbers

    • Pin names

  • All pins are passive

  • Designator is set in properties with wildcard

    • K?, R?, L?, C?, etc

  • Confirm symbol name makes sense and is stored in the right folder (no randomly generated names!)

  • Confirm type is correct (BOM or No BOM)

Footprint

  • 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

Note

Double check 3D models for alignment to pads and for dimensions against datasheet!

...

  • 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)

  • Traced 3D model without checking if it aligns correctly

  • {to be continued as we make more errors (smile) }
