Has anyone ever tried to make a printed circuit board by printing a reverse
image onto a sheet of aluminium foil [with an ink jet printer], then plating
copper onto the exposed trace? This sheet would be epoxied [copper side
down] onto a thin fiber glass board, allowed to set and then caustic soda
would eat the aluminium away leaving the copper trace behind.

Sound feasible? See any obvious problems with the approach?
