proportional environment in both cases. The results were as follows: 1.44mm round lead produces as 1.6mm hole and a 2.4mm pad; 0.8 X 1.2mm lead produces a 2.2mm hole

Posted: 08 Nov 2012 at 2:09pm Since, the PCB Footprint is 100% mathematical calculations there is no way to set a "Hole Size" round-off

) - should I round to 1.1 or 1.05 in preference to specifying a 'non-standard' hole size? 2) If I do run with 1.1mm hole, I am guessing that I should also update all of the pad sizes to match the hole size? 3

; I have the dimensions of the tab, and I can create a slot that will fit, but I'm mostly estimating.Your discussion above about the hole size for round and rectangular pins made me think to post this question here.
