Eventually, after a frustrating session of blanket resoldering that
did no good at all, I came to a power resistor standing up off the
board. It was a component that I had previously twisted. This time
I pulled it, and one leg just came right out of the board. The joint
looked perfectly normal - for lead-free that is - but it had not whetted
the resistor leg at all. How the hell could that take two hours to go
bad, not be responsive at all before that time, and
then when it has gone bad, not respond to twisting, but be so tap
sensitive that you could make it come and go with a feather? I HATE
lead-free with a passion.

If it ever finds its way into avionics, be afraid, be VERY afraid

There is no doubt lead should not be used where it can wind up being
consumed by humans or animals.. It's use in gasoline, paint, dyes,
ceramic glazes, cast toys, trinkets, etc is indefensible. On the
other hand, banning it's use in ICs, and circuit boards is asinine.

Is it really? Think about it: where does the majority of all that crap end
up?

Hint: it sure as hell ain't in approved, safely managed reclamation or
recycling facilities. You know what I'm talking about. So it's the same
with lead-containing consumer electronics as it is with those other things
you mentioned (well, not the same as gasoline, but everything else there
eventually ends up in landfills, waterways, etc.).



Even if it does end up in landfill, how does the lead get back out of the
components and solder, into the environment. Hint, it doesn't ...
