Are you meaning the hand paper shear type attached to a table? if so i would think only for the 1/32 inch boards. for 1/32 i was able to use aviation snips, but even with micro grain carbide G4 fiberglass seems to dull tools. When i was a professional CNC punch press operator, we could see our punches and dies getting dull and drawing more hydraulic force in a single short run.

I have used a manual paper shear for cutting circuit boards; paper (srbp) board almost always splinters, glass (FR4) is best done with one quick shear.
More reliable (even works for acrylic) is to score both sides with a (safety) knife, put the board at the edge of a table or counter top with a sharp (not curved) edge with the line along the edge of the table/top hold down the board with a something hard (wood, a book etc.) then with one swift blow of a book on the overhanging board I usually get a nice clean break.

For FR4 you're supposed to use a diamond cut router bit, that's what I use on most boards. For the really thin boards, metal shears work fine, leaves a nasty edge though, but that can be sanded off.

Just got a diamond-blade tile cutter for $99. Works very well and makes some clean cuts on the PCB FR4. I thought I would get one for $20 off of craigs list, but the guy never got back to me.

I have to say, I've used shears, dremmel and box cutters. This diamond cutter is great. I would have gotten the mega-shear, but it was $330 and $60 to ship. This was $99.
