Re: gEDA-user: 2-layer design recommendations

There is also an environmental and a pcb friendly reason to leave copper
in unused areas of boards. The reason is that copper left on the board
is copper that isn't placed in the solvent. Thus the solvent lasts
longer (pcb manufacturor friendly)  and the copper doesn't have to be
reclaimed from the solvent (environmentaly friendly). I would ask your
pcb manufacturor though if they prefer a solid plain, isolated little
squares or total removal.
