But only in the minds of evil technocrats like ourselves … the ultimate source
of all that burdens our societies. Oppps! That last part only applies to the
lawyers/politicians and used car salesmen … ;o)

Au contraire— 'green' now means 'environmentally unfriendly.'

Dewey,
Lol
I told her that it didn’t matter what color candles she sold as long as they
were GREEN.

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.

John,
My daughter has a flower store in Europe and I advised her to also sell candles
they will need a lot of them soon ☺

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.
