For 8 mil rules, what's a good gap between +5v and ground polys, when
you have both on the same side?  I'm waffling between 10 mils (closest
to 8 while still being a multiple of 5 for the grid) or 25 (my usual
grid setting, and a little "safer" but I can't prove it).


Unless the board is sparsely populated I usually do 10mils (closest to
8 while still
being a multiple of 5).

A rule of thumb that I read in a Littelfuse app-note was to leave 18mils for 1KV
isolation on an outer layer.
