I'm redoing my Diptrace library, and I'm trying to stick to general rules and guidelines this time
When it comes to hole diameter some resources says to add 6 mils to the nominal round lead diameter to get the recommended PCB hole diameter.
I had PCB's with to narrow pad holes before (couldn't fit the preamp filter cap on board, not my PCB design), so I'm just wondering is 6mils is enough.
In general I'm using the same part types continuously (the same lead thickness) so I don't think it may be to critical issue, but some parts are/may go out of production and I really don't want to redo may library one more time
Should I stick to +6 mil tolerance or go wider?
