This whole business of "free thinking" as it relates to the
environmental impact of lead in electronic assemblies is a dangerous
trend.  A lot of hard work has gone in to generating a high level of
hysteria and peer pressure by all the major environmental agencies and
futuristic splinter groups as well as the suppliers of "alternatives".
These people surely know more and care more than the un-washed masses of
industrial engineers?

Question:  If a printed circuit is delivered to an assembly house with
an alternative coating, and then has components attached with tin/lead,
has the long term environmental impact been reduced?  Source reduction
at the pc shop? After many years in that trench, this is a weak
argument.

Question:  Why isn't there an all out effort to produce a metal free
adhesive for component attachment?  This way, we can spend our energy
worrying about the dangers of metal leaching in landfills from only the
components.

Oh my, what if the bennefits from electronic assemblies does not out
weigh the environmental damage it will produce?  Maybe we should just go
fishing, eh?
