I should mention it was a very interesting and informative phone
call. The guy I got (think the name was RICK) tried keeping me on
the phone for as long as possible (normally, if they hear "I wanna
buy something for $60 the call ends quick).

He said, one of the clients is using the heads to print a silver-
conductive fluid onto the boards, which are then heat-cured in the
oven @ 130 degrees 7-15 minutes. This solidifies the fluid. I
said "oh, like solder-paste?" he said "yes". So somehow- these
printers are printing silver to BLANK (i mean NO COPPER) fibreboard
and printing the traces right on it for oven cure. No etching!

The piezo head technology is pretty much the same as what epson
uses. He explained alot about the chemistry and physics involved
with the thermal print-heads (hp technology) and how those heads wont
work for many fluids as the heat alters the molecules in such a way.

Unlike most big companies I call which try to get me off the phone
once they found out I wasnt "the sony corporation" or someone else
big trying to buy a million dollars worth of stuff, this guy kept
trying to fill me with more and more information. If you are at all
a bit interested, I strongly suggest giving them a call, tell the
telephone operator you want to speak with someone about the piezo
heads. The engineer I got on the phone was extremely enthusiastic
about his technology and ready, willing and happily explained all
aspects of the process in precise detail.
