Then...does VP have a future? And, furthermore, is there any nicer products in sight? We plan to buy new in-line machine. Interesting to hear what you got in that Merlin glass...

The fluids used are perfluorinated hydrocarbons and derivatives. These are classed under the heading of perfluorocarbons or PFCs. PFCs, along with sulfur hexafluoride, are the worst vapours/gases known to man as greenhouse gases and have a GWP some tens of thousand times higher than carbon dioxide. Even worse, they have an atmospheric residence time of over 10,000 years, This means that if you lose 1 kg of the stuff, there could still be 400 - 500 g floating around in the air when your 400 x great-grandchildren are around (assuming man survives that length of time). PFCs are also controlled substances under the Kyoto Protocol. Then, of course, they are horrendously expensive. Don't think this won't affect you. VP soldering is fine for plane surfaces, but on electronics assemblies, some of the vapour is ineluctably captured under components, in coil windings etc. It may take hours before this vapour is emitted and each gram lost that way will cost you a sizable fraction of a dollar, despite what the machine makers may say.
