Having to waste all these resources, particularly in these economic times, certainly does not help. Osama bin Laden must be laughing himself silly in his cave—we are doing his work for him.

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.

times

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.
