One I've not seen suggested - do a google on "metal nibbler".

The "cut" will be wider than a saw, but it should fix the
warpage you get with ordinary tinsnips.

I run a small workshop in which we manufacture our own prototype PCBs.

In the past presensitised board has been cut with a bandsaw. The saw blades
life is very poor and the blades break frequently. We have also tried an
electric coping saw with even worse blade life and a small bench guillotine
which tends to lift the presensitised layer from the copper.

I was toying with the idea of using a diamond rod/wire blade fitted to the
coping saw.
Can anyone please offer me some guidance in the best methods they have found
for cutting F/G board in this environment.

Thanks
Rob

Since nobody has brought it up yet, I thought I'd mention that some folks have
reported good results with a blade-type paper cutter.

I've used a nibbler (the $10-$20 variety you can get at Radio Shack and
many other places). It works pretty well, but is a slow way to go, and
it's slightly tricky to get the edge really straight. I wonder
if a powered nibbler would work:

That's a link from Micro-Mark's web site (http://www.micromark.com/). They
also sell two small shears that may work:

Please post your experiences if you try one of these!

Peace,
Tom
