I think it is strange that printed circuit boards are getting
put on center stage. If you were to take the metal toys kids buy from
vending machines at the local grocery store you would find that they
contain more lead in them then your average PCA. Yet you see no
legislation on protecting our kids our environment from those toys that
come from India, China, and other cheap labor countries.

Subject: Re: [TN] Lead-Free, Why?
Dear all,
Maybe the why is deeper than we think and, if so, I sincerely hope it is
for the well being of the humanity. Maybe the political rulers are
smarter and more altruistic than we think and banning the Pb in
electronics is just the pilot project in banning lead in all (you know,
we see how banning works in electronics and then we take on
accumulators).
One thing is for sure, Pb is more related to humanity than we believe.
It exists everywhere and we interact with it on a daily basis. Is this
good, or bad? Medically speaking, having more than a certain level in
one's blood is bad for the health and that's a fact. Now I have a very
interesting dilemma: lead killed Beethoven and made his life miserable,
but, most likely, this condition sharpened his genius. Probably if he
had not been poisoned, his art would have been less powerful. So he
suffered from Pb, but we benefit from his suffering!
So the why still remains... Now it hits us in the electronics, tomorrow
it will hit other fields, but do we really have to do it at all?
Regards,
Ioan
