It behooves one to make a one-sided board if possible. Not sure of all of DJ's techniques but I've made two-sided boards at home. It works, but the little problems are always magnified. Most importantly you have to align the artwork on both sides. I'd recommend drilling a few of the holes for your parts after imprinting one side of the board ... and using these as the index points for your second-side artwork. Punch holes in the second side artwork before ironing it on and slide it down onto pins in the holes you've drilled. Another thing I've done at home for one-offs is to lay out a board in PCB so that the traces are all really short ... and simply use adhesive spray mount to put the 1:1 inkjet printout on a piece of 1/16" phenolic board to use as a drill guide. Then ... I DON'T etch the board but just twist and hand-lace the back/solder-side having the benefit of the components being optimally arranged and with most nets being laced with the excess leadstock from the components. Then if I want to do a PCB most of the work is done. If I know I'm going to pull or swap components I'll make loops in the adjoing parts around the holes. This only works for through hole, this I believe is faster than wire-wrapping even with the PCB step involved. phil _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
