There used to be a small tool that was used to create an island around
a drill hole. it was effectively a micro sized hole saw. The
technique was to drill holes in copper clad where you wanted them,
isolate this hole with the tool (as needed) and then bridge from
island to island with the parts.
You've probably seen that one and decided it's not what you want. A
similar approach would be to use a dremel as a router, make a small
template that is large enough to manage, and has various patterns in
it, then use the dremel as a router to remove the copper around that
island. Never seen anyone do this, but it would have an advantage
that you could make templates of your favorite circuits with a sheet
of scrap aluminum, isolate as needed, (no through holes required) and
have essentially the same layout each time.
you'd have to be somewhat careful with the depth setting, but a small
fixture could be made to allow you fast setup.
