I have been sitting on a bunch of 4″x6″ CEM (Composite epoxy material) that I got from a copper clad vendor online. I thought it would be cool to use for prototypes since the board is kind of ugly looking. When I first got it I found that the thickness was giving me some issues with cutting it like I do with my copper clad laminate. I tried with my chop paper cutter and it almost broke it. I also tried a jig saw and the blade would gum up and start melting the board. The Dremel took forever to cut it and it would also gum up the blades. I was about to give up when I ran across some plastic cutting blades for my scroll saw. I used Ryobi skip tooth 18.5 TPI blades and it cuts it like butter. I am excited that I can start using this clad for future projects.

Just thought I would share my trials & errors.
