I have some of the super-thin 0.01 boards and have been thinking the same
thing. My colleague told me they are laminated together for thicker boards,
so I thought I might try it as well. I was thinking I would etch two boards
and epoxy them together, copper sides out, probably squeeze the whole thing
between some pieces of wood in the vice. Then use pieces of ribbon cable
soldered at the edges for a cheap easy "via", 16 lines at a time.
