Hi Brian,
I fully agree with you--on both counts.
Unfortunately, you need to lay the blame for the need for VPS squarely at the feet at the misguided 'greens' in Brussel.

Subject: Re: [TN] Vapor Phase Soldering









Yes, some do, at least as far as the practical aspects of soldering are 
concerned. However, very few even  cast a thought to the environmental 
aspects, which are horrendous. The radiative forcing due to halocarbons, 
mostly fluorinated) has increased from near-zero to an average of 0.34 
W/m² in the last 50 years; this is about 21% of the total net 
anthropogenic climate change effect (IPCC 2007 Fig SPM2). The 
perfluorinated compounds used in VPS are the most pernicious of these 
because their long atmospheric residence time (>10,000 years) make them 
continue to have their effect over many tens of generations to come. 
 

As an engineer, VPS is the best thing since sliced bread. As an 
environmentalist, it is the worst thing since Noah was told to build his 
ark.
