Electronic – SMT pads on both sides of the board

padssurface-mount

Is it possible to put SMT components on both sides of the board with the pads touching? I don't want the pads to be electrically connected, but my PCB program (gEDA PCB) warns that they are shorted. Is there any way to avoid this?

It's done all the time, the software I use doesn't give a warning. Contact the support people for your PCB software, they should tell you how to avoid the problem. Or, just ignore the warnings, the boards should come out OK. You could check the Gerbers with a program like GC-Prevue to make sure.
