Homebrew PCBs

Mark,

I can see how that curving could crack vias and thin traces. 

Before I made my finger brake ( http://rick.sparber.org/smfb.pdf ), I used
aluminum "coil". It comes pre-painted on both sides with different colors
(your choice). The stuff bends with light finger pressure and cuts easily
with scissors. Yet when folded up into a small box, is plenty strong. Back
in Illinois, it was used to wrap wood on the outside of people's houses.
VERY resistant to weather. I bought a 50' x 1' wide roll about 25 years ago
and still have some left.

Rick

Subject: Re: [Homebrew_PCBs] PCB cutting

I use metal snips for boards no bigger than 2" because anything longer and
the board starts to curve up or down depending on which side I need to use.
I would like to use PCB material for project enclosures too, just can't
justify the costs for even small enclosures.
