I'm not sure how it can be done in eagle. In most any other layout software you'd just define the padstack so it doesn't have a pad on top where you can't solder. Since the pads in eagle are a separate single layer that might be impossible for all I know. You might be able to fake it by using SMD pads, but it would be one horrible kludge, should fit right in with Eagle. There's a list 'specially for Eagle, you might have more luck here: eaglecad@yahoogroups.com Regarding soldering on top side, It's possible for turned sockets, which expose a little of the metal, but tricky.

This is one reason why auto-routers have limitations; a lot of folks here do most or all of their layout manually.

This feels like a kludgy solution to me, but I have used it at the prototyping stage. > > --- In Homebrew_PCBs@yahoogroups.com, Brian Lalor <blalor@...> wrote: >> >> Does anyone know if it's possible to tell Eagle that standard holes >> for through-hole components aren't automatically attached to both top >> and bottom layers?
