Homebrew PCBs

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.
