ROHS Roll back the lead-free initiative 12 ROHS myths - 
9-13-2007 - EDN

    http://www.edn.com/article/CA6477864.html

____________________________

The detailed EPA investigation described /linked below is 
said to conclude that ROHS sucks and that it is worse for 
the environment than tin-lead solder was. I skim-waded 
through the summary report - and it is highly interesting 
and PROBABLY supports the claimed conclusions - but they are 
very mealy mouthed in saying so.

The main report looks like even more fun. The executive 
summary says even less about conclusions except effectively, 
in my words "each user can use the data as input into 
established evaluation systems to draw conclusions available 
to their own interests."

The relative PDF size are interesting.

Solders in Electronics: A Life-Cycle Assessment

This life-cycle assessment (LCA) evaluated the potential 
environmental impacts of selected lead-free solders as 
alternatives to tin-lead solder. LCAs, which are generally 
global and non-site specific in scope, look at the full life 
cycle of the product being evaluated, from materials 
acquisition to manufacturing, use, and end-of-life (i.e., 
final disposition). This LCA assessed impacts related to 
material consumption, energy use, air resources, water 
resources, landfills, human toxicity, and ecological 
toxicity. The partnership also investigated leachability and 
recycling of solders at the end of their lives. The solders 
evaluated were: tin/lead, tin/copper, tin/silver/copper, 
bismuth/tin/silver, tin/silver/bismuth/copper.
