For the D-SUB connectors which I was proposing this, it shouldn't really matter, as the pad is left unconnected anyway. If we name all the mounting pads "Shield", then I don't think DRC will have an issue in the event they are connected to something.
I think it would have to say something :D if it doesn't it is wrong, in my opinion... even if it's only for mechanical fixturing it must comply with electrical clearance *at least*. Especially for connectors since shields usually go to the chassis *and* they actually have to be grounded to be called shield :P For unsupported holes (i.e. non plated, non conducting, tooling or fixing holes) thing are a little different but you should anyway keep manufacturing clearance (which can be from 0,1mm to 0,5mm depending on your drill process). Keeping the D-SUB example, a plastic boardlock like the one I use only need mechanical clearance. A screw fastened one need both mechanical and electrical clearance (maybe even below the head/nut, depending on you reliability level) -- Lorenzo Marcantonio Logos Srl _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
