Oh please!

Do you think I came up the Clyde in a banana boat or what?

Currently aircraft are flying the world with boards running at temperatures
so high that 'air conditioning' systems are utilised to maintain a safe
window of operation. Both aerospace and automotive companies are running to
embrace lead-free technology on the basis that it could get them out of this
thermal management bind. Ford have already made the jump.

Get your head out of the sand and look at the reasons why major companies
are interested in the technology. If you and others want to play with the
green issue carry on - it's peripheral, but don't tar me with your
hysterical brush, your wasting time and your pursuing a dead argument!

Oh and by the way G. Bush didn't kill off the Kyoto agreement, the poor
bugger only stated up front what Clinton knew and wouldn't state (heh, why
should he, he was outta' there, keep things sweet, it was going to be
someone else's problem after all....) - that it would never make it through
the US legislature.

Oh and as to the so called problems with deviation of compositions lead-free
alloys, do you really think anyone is running with 63/37? Man, that's pure!

Go to the TechNet forum check out the , latest dialogue on the analysis
breaks for tin lead pots, that's for real.


Best regards,

Andrew and Doug
How does one maintain the binary Sn 3.5Ag or Sn 0.7Cu at those precise
eutectic compositions?  And I note that the pasty zones are very large when
compositions deviate. What happens when the ternary SnAgCu alloy in SMT
paste
meets and joins the SnCu alloy used in wave soldering?

How do you think the consumers of the world will like the reduced product
lives.  And the product liability suits for failed ICs, turned into sieves
by lead-free melting temps-- can't wait.

Would you fly in an airplane whose black boxes are lead-free or use a
pacemaker....

So how much lead-free is being used today?  Is any one making money from
lead-free?  How many lead-free-ready ovens have BTU or Vitrronics or Cookson
sold?

Lead-free is a bad, expensive joke, and not even Green.
