Homebrew PCBs

I don't see how your comment has anything to do with Mikes idea.

Yes, the toner and the paper are charged the same. So what? They 
have been loosing their charge since they came out of the printer 
(static dissapates) and now have little or no charge relative to the 
environment around them as well as no charge relative to each other.

The point is that he has charged the blank PCB now. Some or most of 
the Toner will then jump up to the blank. As long as he flips the 
blank over before the charge dissapates, that toner is going to stay 
on the board.

Now, he takes the blank, with the un-fused toner on it, at sets it 
in a hotplate. At this point, the toner melts onto the blank. There 
is no paper to remove, the toner isn't going to come off and we are 
ready to etch.

I think its brilliant. Any other snide remarks you want to make? or 
are you just repeating what you learned from others as documented at:
