Using my public library footprint 0603, you can place the pad-pad 20 mils apart, & fit 1 10 mil trace under the 0603 center with 7-7-7 clearance PCB rules.

The silk was designed to allow perfect super-imposition, all my library parts should line up very good with 5 mil snap grid for both routing & part placement. Same goes for 0805, 1206, 1210, ect.... Tested in a lot of miniature battery powered equipment, no problems at all.

You can download the lib here:

I set my 0603's up with a padsize of 32 mil , outline of 28 mil pad centre to
overlay centre and place them using component grid of 8 mil and snap grid of 4
mil. This allows placment so that the overlays can sit on top of its neighbours
overlay exactly and there is 24 thou clearance between pads. Then normal 8/8
routing can be used and a track can go between adjacent 0603 underneath the
overlay with no DRC errors.
