What you really want is the high volume technique of using carbon conductive ink traces and insulating layers silk screened on and single copper FR4 or FR2 or composite paper/glass boards with no drilling, just punch press tooling for holes. But then you have to order by the panel full and pay some setup charges for any change once the punch press tool is made. _______________________________________________ geda-user mailing list geda-user@xxxxxxxxxxxxxx http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
