First time tried to make pcb, used Sharpie Ultra Fine marker and ferric
chloride from Radio Shack. After 10 minutes in solution, with agitation, market
lines were degrading badly.
Ransom: I have done tiny bits of PC-board sucessfully with a regular
Sharpie, but ONLY a very new/fresh one! Older ones that still work OK on paper,
etc, won't work well at all as resist, just like you say.
However, I discovered some new Sharpie "INDUSTRIAL" fine point fiber-tip pens
that LOOK the same except for the different color logo on the body of the
pen, and it LOOKS like this may be "tougher" ink, as it claims to be "super
permanent ink". BUT I haven't had a chance to try these, yet. Seems they were
noticebly more expensive (at the "office store") than the "regular" Sharpies. I
just gotta get off my lazy antique duff and go TRY a scrap, and SEE. Once I
do, of course, I will REPORT here!
