RE: [Homebrew_PCBs] Re: Double-sided on random-size board?

Actually this can easily be taken up another notch:  A 4-Layer board.

The backside can be a solid ground plane on one board and a power plane on
the other board with a double layer of tape as insulation between them.

Drill big clearance holes in the opposite board to clear wires poked through
and soldered for power or ground connection.  

The connections will be rather large so not suitable for a tight board but a
lot of projects would greatly benefit of a 4-layer board with solid ground
plane and power.

I've done the same thing, but use 3M double sided tape sheets to tape
the two halves together. Never thought of the double-smd-sided trick
though...
