Dimensions in the silkscreen! Maybe I'm the only person who hadn't thought of it already, but that looks super helpful for ad hoc work with your parts.
±50 nm dimensions maybe need temperature & humidity specs tho.
Are you sure? yes | no
Lol, we don't need any GD&T here. And yeah, my first career I was a mechanical engineer, so putting dims right on the thing was something I always wanted on other people's boards when I used them, so now it's up to me.
Thanks!
