My PCB manufacturer (which i use at work) uses a green material as
backing, with a white coating on both sides. The stuff is a bit like
MDF, but i don't think it contains wood chips. It's more like very bad
phenolic board if that makes sense. They sometimes send pieces of it
(used, you can see the drill pattern of other people's mighty
complicated boards) with the PCBs, and it makes good workbench surface
protection because it is sort of heat resistant.
I suppose the proxxon drills are by far not as brittle as carbide
drills, good idea if someone doesn't want to make a drill press for
this purpose.
