Hi!
I have one of these VFD display (
http://www.jogis-roehrenbude.de/Roehren-Geschichtliches/Nixie/ILZ-1.htm ) russian made and it has a
circuit "printed" on glass. The traces are clean and the substrate is
transparent, anybody knows how these are produced? I would like to
have a glass / transparent PCB with solderable tracks.
Thanks!
