So I have one question about Ronald Lasky's article. He wrote: "The man in
the photo above, from this article, is reclaiming solder to sell to a metals
merchant.  It is almost certainly lead containing solder.  He will cook his
supper from the same pan that he is using to gather the solder.  In a short
time, as RoHS compliant products become dominant, the solder will not
contain lead.  I think we will all sleep a little more soundly knowing
this."

Why is he going to sleep better knowing that this guy will continue to eat
out of this same pan long after lead is out of the solder? I guess over time
the lead will leach out ;-) This guy will continue to eat out of this pan
after melting numerous different lead-free solders. I'm sure glad that there
will no longer be any hazardous materials left in recycled electronics after
the switch to lead-free solder. I feel a nap coming on :-)

In the words of Raymond Barone's wife Debra; "Idiot!"

That Ronald Lasky would publish such garbage is both disingenuous and
irresponsible. It is easy to see the money talking.

Lasky looks at RoHS 3 years later

August 18, 2009

"Dr. Ron Lasky put out a blog indicating that the transition to
RoHS-compliant electronic components has been a success. In his blog, "RoHS
3 Years Later
http://www.indium.com/blogs/Dr-Lasky-Blog/RoHS-3-Years-Later/20090726,12
,3433/ ," Lasky - who has spent 10 years following the lead-free movement -
notes that more than $1 trillion dollars worth of RoHS compliant electronics
have been manufactured "without significant incident." He notes that the $1
trillion figure is derived by the total parts produced since the July 1,
2006 RoHS deadline and includes parts that go into countries that don't have
RoHS laws. Since most component manufacturers did not run two lines of
compliant and non-compliant parts, even parts going into areas without RoHS
laws were RoHS compliant.He explains that part of the success of the RoHS
conversion was the lack of hard monitoring by the European Union. The
relaxed compliance atmosphere allowed the industry to make a smooth
transition without interruptions in supply of electronic parts and finished
goods."

"Lasky also notes the unintended benefit of the RoHS conversion. "In
third-world countries, electronics are recycled for usable electrical
components and scrap metal," says Lasky. "Almost all of this recycling is
performed unsafely. With RoHS-compliant products, this unsafe recycling will
be done more safely.""

How would Lasky know this to be true?  Where's the data?  Dr. Henning
Leidecker at NASA Goddard Space Flight Center
http://www.msnbc.msn.com/id/21151552/wid/11915829/ has advised me that there
are failures. NASA is sworn to disclose them or they would not be told about
them.  Catch 22.  Why?  Lawsuits, that's why!  

Has anyone died due to failures in Medtronic pacemakers (which were subject
to an FDA recall due to tin whisker shorts)?
http://www.fda.gov/ICECI/Inspections/InspectionGuides/InspectionTechnica
lGuides/ucm072921.htm  FDA does not say in this report.  There is nothing in
the open literature that I've been able to find.  That leads me to conclude
that the cases were settled out of court and the records sealed. Does anyone
here know otherwise? 

According to this blog
http://scadaperspective.com/pipermail/scada_scadaperspective.com/2008-Ju
ne/000748.html there are failures (again, the company experiencing them is
not mentioned):

"... according to the factory manager of one of the largest industrial
automation and embedded computing companies in the world, it isn't fiction.
What they've done is increase infant mortality testing, heightened quality
requirements, gone six sigma, and they are still seeing a sharp rise in
warranty claims due to solder issues."

Isn't 3 years too soon to tell?  Three to five years is the expected time
for whiskers to grow long enough to cause shorts.  Lets not pop the
champagne cork just yet.

Se also http://www.calce.umd.edu/tin-whiskers/TINWHISKERFAILURES.pdf

It is premature to suggest at this time that there have been no "significant
incident" failures due to tin whiskers.

Unless the persons doing the analysis knows how to detect them (10% of them
are visible to the naked eye, the rest require magnified inspection and
special lighting, knows where to look for them (presuming they are not
vaporized in the shorting incident), how would Lasky be so certain such
incidents never happened?
