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?
