See original thread for pictures and additional info: https://forum.kicad.info/t/abnormal-zone-to-pad-clearance-for-rrect-pad/15055/4
A rounded rectangular pad with thermal spokes does not have the correct copper zone clearance, and an unexpected keepout is created, the size of which depends on the corner size of the rrect pad.
To reproduce:
- Create a rounded rectangular pad with a corner size of 25%.
- Create a zone connecting to this pad with thermal spokes, default clearance settings are ok.
- Fill the zone, and observe the additional unexpected clearance in the corners.
- Change the pad corner size to 1%.
- Refill the zone, and observe the clearance being reduced to what is expected.
- Change the pad to a rectangular or oval pad size, and the clearance is always adhered.
For solid connection zones there is no problem, obviously - only for thermal spoke connections. |
