You told her that so the burnt offerings would reveal their wicked past
or that today's enlightenment was just a waxen image of its former self.

Good one Werner
Would the eco-enemies have something to do with the current economy?
In Belgium 1/3 of their mobile network went down (and they still don't
know why).

It is a minimum of 3% Pb not exactly 3% Pb.
This whole Pb-ban is so silly [or would be if it were not so sad].
In the name of being 'green', we now use more energy [so much for
sustainability], more vapor phase soldering [so much for being
eco-friendly], throw more things in the garbage [more environmental
friendliness not to say anythingabout inconvenience, economic loss and
reduced safety], retrofit Pb-free components with Pb [ wouldn't it be
better and easier making them with SnPb solder in the first place],
With all these 'green' friends [who do not know what the hell they are
doing], who needs eco-enemies.

I was wondering if there are any comments about this whisker mitigation
strategy
announced in Electronic Design News yesterday by Bourns. This says "hot
dipped
tin" as in lead-free. Seems to me if this is really pure tin, it would
be
really hot exposure of the components, and I am seeking any data to say
how much
better "dipped tin" would be than "plated tin" for mitigation. Seems to
me they
could hot dip 3% lead in tin, but I guess that would be a special order
for RoHS
exempt industries.

One of the concerns of companies complying with lead-free <
http://www.edn.com/hot-topic/48810/rohs.html>
manufacturing processes under the European ROHS <
http://www.edn.com/hot-topic/48810/rohs.html>
(Restriction of Hazardous Substances) directive is the tin whiskers that
can
develop over time on tin plating. Trim pot manufacturer Bourns
<http://www.bourns.com/> recently announced it was shifting its entire
line to
a new hot-dipped-tin process for the trim pots' terminals. Bourns will
no longer
offer the old matte-finished parts because of the tin-whisker danger.
Although
the company made the change at the request of its customers, it won't be
passing
the price increase on.
Emill Melliz, Bourns' potentiometer product line manager, puts the price
increase at between 5-7%. Why is Bourns eating this not-inconsiderable
amount?
They see it as a way to increase market share in a very competitive
economy.
Smart company.
