Homebrew PCBs

OK I can now say with no uncertainty that this WHITE Uni Paint Pen is the
best etch resist (in fecl) that I have ever used, I had problems getting it
off !


I just wrote on the surface, as quick as I could to try to get a thin line
(not width but 'height') and drew a few pretty stars etc.

It resisted hot etching, agitation, and severe wiping of the surface with an
acid wet clotch, it resisted the nail varnish remover and I had to really
scrub hard to remove it.

It works fine in the plotter if a little 'wet' I may have to make future
boards take that into account, or slow the plotter

Need to make a pen holder for it now, then I can do a real world test.

Its looking very very good for this pen.
