So you're saying the justification for doing this was really a stretch,
but not beyond R.E.A.C.H..

Subject: Re: [TN] Lead-Free Problems?

Yes, because it is cheaper to build leaded product than it is to build
Pb-free, contrary to all those people who said that the cost of
manufacturing 63/37 solder to the 1% who needed to use it would drive up
its cost. I'm still laughing at that one.
In addition to all of the warnings about reliability issues and
increased environmental impact from higher processing temperatures, a
number of us pointed out that if the lead is removed from solder and
replaced with more tin plus silver, there would be a shortage of tin and
silver, and that happened. Increased environmental impact was also seen
from having to mine more lead to get more tin. Many on this forum also
forecasted that.

The increase in demand drove up the price of tin and silver such that a
surcharge is now being placed on every gram of lead-free solder. This,
along with higher energy costs, is making it more expensive to process
Pb-free assemblies than leaded. Again, just like we said it would.

So it stands to reason anything lead-free, including answers to
questions, are gonna cost a thousand times more.

In summary, we have this to say to the EU; 
"Well, we told you so, and you didn't listen. Now pay up, and next time
listen to the industry experts so you never again legislate something so
stupid as RoHS."

When did the 64 thousand dollar question inflate into the 64 million
dollar question?

Are lead free questions worth a thousand times more?

Of course, the $64 million question is: If that IS the case, then what 
type
of solder was used... SAC305, SN100C, etc., etc. And who made it? I 
suspect
we'll never know.

Subject: [TN] Lead-Free Problems?


I thought this was worth sharing. The Chicago Tribune has an article;
"Coolest electronic gear way to hot for its own good". In the article
they write:

"The Xbox's failure problem has generated more than 1,100 complaints to
ConsumerAffairs.com, an online publisher of consumer news and recall
information.

Adam Carpentieri, who said his online repair site, Xbox360-pros.com, had
fixed more than 2,000 systems, surmised that the culprit was the
lead-free solder Microsoft used to comply with European Union standards
for reducing hazardous materials in printed circuit boards.

As the solder repeatedly heats and cools, it cracks away from the
circuit board's tiny copper connections, causing them, in turn, to
separate and fracture."

Could that possibly be?
