http://groups.yahoo.com/group/Homebrew_PCBs/message/572http://groups.yahoo.com/group/Homebrew_PCBs/files/Sign%20Cutter%20to%20make%20PCBs/You don't want to stick it onto the board before you cut it. For a
variety of reasons: 1. you'll dull the point of the cutting blade
as it slightly scores the copper 2. you will not be able to "weed"
the vinyl (ie, lift off the areas you want to etch) because that
stuff sticks like gangbusters 3. few vinyl cutters will feed a
rigid thick board.
To sandblast that much metal away, you'll need to use a special
sandblast resist vinyl, not regular sign vinyl. I'd be worried that
the thick stuff won't allow very thin traces or holes, and that it
may blow off on the thin traces.
Flame suit? Who's going to flame you for brainstorming? That is
what this list is for!
