Werner And when the Brussels greens (sprouts?) decide to restrict perfluorocarbons? I think this may happen sooner or later. It would be almost impossible to devise a VPS machine with zero emissions and a practicable throughput. Depending on the components used, it can take days for an assembly to lower its emissions to undetectable levels after soldering.
