Bill and All:
While it is sad that most of the industry is simply being pushed into
this and not making a conscience choice, it is clear that this ship has
sailed...
We are doing our best to inform the community that even if their
products are exempted by RoHS their supply chain is in flux and they
need to manage the changes if not the compliance. I wrote the following
article for our Customers in the Medical and Military industries and it
covers a few of the topics in this thread including, the fact that lead
in electronics should not be at the top of the worlds list of problems
at the moment:
http://www.medicaldesign.com/articles/ID/12424
With all of that said, there is one other spin on this worth looking
at... Economics! There is going to be a lot of re-design required in
the next 12+ months, there is going to be a renewed demand for component
engineers, design engineers, prototyping and engineering firms.
Hope for the industry...
WEEE actually does more to drive 'environmentally sound' product
lifecycle designs and practices than RoHS...
Imagine what the landfills will have coming there way in the next year:
- Newly Obsolete Leaded Components
- Leaded Electronics no longer saleable
- Spools of 'bad' solder
Oh well, I hope the economics of this drives a recovery to the US
electronics industry. I am enjoying this thread, I'm glad some still
think in terms of revolution.
Don't shoot until you see the whites of their eyes,
Joe

Yea I read that article posted there about the Millstone Dominion
Nuclear
Reactor shutdown on April 17th 2005.due to Tin Whisker growth on a
circuit
card in the controls for the station. It looks like NASA has been
tracking
Tin whisker growth for the last 60 years or so... they should have a lot
of
data on the subject... They mentioned the 9mm a year growth in the
article.
That's about a 1/3 of an inch which would short most IC's with normal
gull
wing pins... even DIPs would short...
And they still don't know what the mechanism is that causes it... only
that
Tin/lead alloyed together reduces it greatly.

Yes, but heed the disclaimer under the picture:
"Motion depicted is for simulation purposes only"
I think the world-record whisker growth was 9mm per YEAR!
