Default So what's the truth about lead-free solder ?

Follow the derogations/exemptions.
Military , aerospace & medical do have derogation from WEEE and RoSH, but
can anyone nail down precisely why they are exempted.


I suspect it is because these fields are considered "life-safety"
fields.
Even ordinance, when you think of it in terms of friendly fire
incidents.
They probably just don't want to recertify their processes, or don't
have the time to do it right.

But the "Truth"?
That's much more elusive.
Does RoHS result in a better environment? I don't know, but I doubt
it.
The sheer number of TV sets that will be obsoleted in the coming years
due to the migration to Digital Television will probably swamp the
RoHS "gains" by orders of magnitude.

Ditto for the batteries used in some electric cars, and the US's
(likely?) ultimate reliance on it's vast coal reserves to power all
this crap. And that's if Global Warming doesn't get us first...

Bottom line: I don't think the environment gives a sh^t about RoHS,
or WEEE.
I think we need fewer people, and less "disposable" crap from China.
