I am looking at the PCB footprint diagram of a DC-DC converter (and some other stuff like the measurements on servo splines, etc.) And there is a symbol that I am not sure about.
The symbol is: ø
For example:
Servo horn gear spline: 24 segment/ø0.576
An arrow pointing to a square pin of a DC-DC converter: 6-ø1^±0.1 (superscripted)
An arrow pointing to a PCB pin hole for a DC-DC converter: 6-ø1.5
THe numbers almost never have measurements, but are implied to be in mm (as far as I know).
