Oh well you asked for it..
I was looking through the EU web site for the latest round of exemptions,
Swatch has an exemption request in on the latest round.Why? - Well being a
typically efficient Swiss based company they started to task of RoHS
conversion years ago. After 2 years of intensive research they implemented
the process in mass production in June 2005, they started shipping and found
massive problems with reliability due to tin whisker growth which caused
them to stop shipping. They believe that this will be a problem with any
pitch under 800 microns or around 32 thousandths of an inch.
They have switched back to tin lead solder, and have applied for an
exemption the document is on public display at the EU web site - here is the
link which I have made into a small link here

If that site overloads don't blame me but do send me comments please through
the site or by response to this email.

Subject: Tin whisker position and China translation
Just saw the iNEMI press release on tin whiskering, tin whiskering is now
official??.... I also found on line the AeA translation of the China RoHS in
the full version which might be a useful document. I have put the links in
the library at <http://www.rohsusa.com/> http://www.rohsusa.com under the
new technical papers banner, so just click on it, to get to the new papers
and links. There are more to go up there but it's getting a bit late.
I just had a really interesting email from a consultant in New Zealand who
applied for an exemption in 2004 for lead in solders on environmental
grounds - which apparently never made it through the TAC. I have asked him
for permission to put the whole thing on line at the web site, but take this
opportunity to quote a snippet from his e-mail:
===========================================================================
===========================================
The submission was unminuted in the unofficial TAC minutes but was minuted
in the official minutes of the meeting 10 December 2004. The TAC overturned
it with the comment "entry 19: as this is normal solder it should not be
studied:" This is the only official record of the submission ever being
made. I decided not to pursue further action as being a small
company.............
Curiouser and curiouser
I will advise when I have the full thing on line and will link to his web
site. If you do go to the RoHSUSA web site check out the "my 2 cents"
feature if you want to get your views exposed to a large audience fast.
Have a great day all.

Subject: 100000 hits at Push back - thanks to all
Thanks to all those that have been interested enough to go to the web site I
put up 13 days ago. The site has taken over 100000 hits in that period.
This week, to enhance the blog section I am putting up two new features, the
first is an anonymous ftp site so that people can upload photo and text
examples anonymously as they find issues without necessarily dragging the
company name into the issue.
The second item is a list server to enable people to discuss the items on
the blog site, make improvement suggestions for the site, and be able to
discuss the defects presented as they are sent in.
If you want to be advised of upload instructions for the anonymous ftp site,
or want to subscribe to the list server when we get it up please let me know
by email or at http://www.rohsusa.com <http://www.rohsusa.com/>
It is by the way free, and no we are not making any revenue from this
operation it is a service to the electronics community. If you have not seen
it yet swing by the blog site at http://www.rohsusa.com/blog if nothing else
you might appreciate the English sense of humor..
Kind regards.
