Homebrew PCBs

JohnM, I have done .5 mm also with no trouble. It amazes me that it 
can work so well - seems so crude but works so well!  I appreciate 
the helpful tips too about the air bubbles. If you look at my most 
recent project at http://kenny.trussell.biz/pcboards/, you will see 
I had problems with coverage and touched up with a Sharpie pen.

I have not done double-sided yet. I do have a question for someone 
about the "pouch". When you slide the board in, how do you assure 
that both sides of the pouch are still equally positioned? If the 
paper curvature is different for one side than the other where edge 
of the board meets the bound side of the pouch, wouldn't you get an 
ofset? (not sure I explained that well) For single sided boards, I 
trim my transparency or paper (whichever I am using) to just the 
outline of the board. Do you keep it a lot larger? Help from all 
appreciated.

I am working on three related board layouts now. At least one could 
be double-sided.

Kenny
