That should work fine. Just do not have any runners next to the edge. I have used 10mil and thinner FR4 making PCB that were 3 x 3mm. I laser cut the PCB for the very small PCBs.

I have a project idea that would require hundreds (possibly thousands) of very small PCBs, each one being a circle approx. 1/2 inch in diameter. Does anyone know if it would be possible to punch them out of thin FR4 with a punch press? That is, use the material that is normally discarded when punching out a hole. Aside from that, what (if any) are the issues with using thin (0.010" - 0.030") PCB material in general? -p.
