Subject: [alt-beam] Re: PCB etching
If you photocopy it onto a transfer sheet or whatever or laser print it
onto the transfer sheet you _DO NOT_ need to flip or mirror it.
_ViSuAlIzE_ it. The black part is what the electricity will flow
through. Again, visualize :) The black will cover the copper, therefore
not allowing the etchant to etch it away. And we end up with all the
copper gone except for what was covered by the black.
Happy PCBing,
Kyle
