Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Well, in about 10~15 minutes we should know something, what, I don't
know :-)

I got some ink out of that cartridge. I used a piece of wire to
smear some around on the PCB board. I also shook it to get a few
drops out and used a coarse brush to "paint it" on the board. Using
two sample boards....

1) I hit with the heat gun for a few seconds to make sure the ink
was dry.

2) didn't do anything special - just let the ink air dry for a few
minutes.

Do not expect positive results though. This is yellow ink, and
being yellow it won't have much pigment in it like the black stuff
has. Which is why I think certain color sharies work bettter than
others.

To answer stefans main question and the one I too suspected would be
a problem - beading. Nope, I could not see any evidence that this
ink would bead up.

I also did not do anything the to PCB material. It was a cut off
piece that I know is pretty decent quality as I just etched a few
other boards from it a few days ago.

I am etching in ferric chloride so that is the etchant for my test.
