Vapour phase soldering is an excellent asymptotic and anaerobic
soldering process. It has two main disadvantages:
- the primary fluid used costs a fortune
- both the primary and, if used, secondary fluid vapours (PFCs) are
greenhouse gases and have atmospheric lifetimes counting into the
thousands of years and have global warming potentials up to 10,000 times
worse than CO2.

PFCs have been targeted under the Kyoto Protocol but how they are
handled is up to individual governments, as the measures to be taken are
a basket with freedom how to handle specific global warmers.
