It's an abbreviation for "mille", same root as the "milli" in millimeter. Common in electronics for describing trace widths and pitches, even outside of the US simply because there are lots of parts laid out in whole numbers of mils.
8 mil traces on a DIY circuit board is pretty good, it's good enough to be able to do some quite fine surface mount parts.
