Footprints
Component Centers
Where they belong
Is it the same for everyone, or stored locally by user?
Define a width and length for crosshairs
Courtyards
Can silkscreen be outside the courtyard?
Set specific courtyard distance from component outline
Set specific widths for courtyard + component outline
Silkscreen/Top Overlay
General guidelines for silkscreen markings
Pin 1 dot - define radius, thickness, min distance from pads
Pads
Establish annular ring convention?
Should we include tolerance data?
How should we handle components which say they’re (for instance) 8-SOIC, but recommend a footprint that’s different from and not encompassed by the existing 8-SOIC footprint?
Proper procedure if you can’t find a good 3D model online
Guide on how to import footprints from Ultra Librarian/snapEDA/etc.
...
define standard convention for Mechanical pin designators (M? vs. MNT? or similar)
Component Parameters
Case/Package vs. Package parameters?
Component Revision
Component States
Proper procedure if you review a component then catch an issue
If “In production” part has a minor issue, do you bother tweaking it? And if so, do you return it to “in production” or just make it “Reviewed”?
If this happens, and a new “reviewed” revision is created, do you have to roll back all prior approved revisions to drafts?

Schematic Guidelines
Should we eliminate the units (ohms, Farads) from passives, since its assumed? (i.e. 100n instead of 100nF)
Should we go to a standard of using net labels like “3V3” instead of “3.3V” for improved readability?
Similarly, we could do “4k7” instead of “4.7kOhms”
