Homebrew PCBs

I've just been looking at the Avecia Jetrack ink jet resist, and am waiting
for Xaar to get back to me about a suitable piezo printhead. I'm not sure if
an Epson print head would work, as they are designed for aqueous ink,
although it might be worth trying.

I've spoken to Avecia, and they will be sending me some sample ink. A
company in Italy is apparently already using this technology for making
PCBs - the machine costs about $150,000.

The ink needs to be cured as soon as possible after application, as it tends
to spread with time.

To get accurate positioning of the printhead, I would think that some sort
of X-Y table would be required, or something much simpler, faster and
cheaper can be
designed using polar co-ordinates.

Both Xaar and Avecia are in the UK, which helps as far as I'm concerned.

I'll keep the group informed.
