Homebrew PCBs

Interesting point. Presumably it is not just Teflon. After all, how do manufacturers get on with the huge variety of goods that have non-stick coatings for use in conventional ovens? My kitchen oven can get up to 250 deg C .I have used it for annealing milling cutters but it is a bit big just for knocking up the odd prototype PCB.

I guess that, so long as it can get up to about 240 deg C inside it stands a chance but I am not so sure it could get that hot. Certainly, I am not sure enough to try buying one just to see.
