Subject: RE: [LF] RoHS Opposition (on Pb) isn't sound (SMT Sep 2006)



The article is not up there yet Dave the site is still showing August, I
look forward to seeing it though.



Sound scientific data will always be just that. Opinions, driven only by
commercial and political pressures will never change the facts -



I guess, given the fact that rightly or wrongly the law is in place on "no
lead soldering" we will soon find out whether or (potentially very
embarrassingly) not the emperors of the lead free solder movement have the
reliability aspects adequately covered as lead free is the only game in
town.



Whether they do or not, the environmental impact of the replacements as
stated in a plethora of sources is not going to change. The replacements
have a much higher environmental burden than leaded 63/37 tin lead.



Lead in solders RoHS legislation is NOT a "slam dunk" environmental issue,
since clearly no overall assessment of environment impact has ever taken
place by the commission, note they way the commission represent the reason
for RoHS - as detailed by this excerpt from the commission in a letter to me
:



 ==========================================================================

I reply on behalf of Vice-President Margot Wallstrom and Commissioner
Stavros Dimas.



Further to my e-mail of 30 June 2006 on the same subject, I recall that the
aim of the RoHS Directive is the substitution of lead, mercury, cadmium,
hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated
diphenyl ethers (PBDE) in electrical and electronic equipment, where
alternatives are available, in order to facilitate sound recovery and
prevent problems during the waste management phase.

 ===========================================================================



The really interesting comment in that and every other communication that I
have received from the commission is this one:



 ===========================================================================

Please note that this opinion of the Commission services is not legally
binding since a legally binding interpretation of Community legislation is,
under the Treaty, the exclusive competence of the European Court of Justice.

Yours sincerely,



Klaus Koegler

 ===========================================================================



So I guess whatever the reality of the situation at the end of the day it
will be up to the courts to decide. Whether that case is a massive loss of
revenue stream caused by substitution and subsequent failures, inability to
manufacture or failed electronics in a safety critical situation - who
knows, we can only wait and see.



I predict that the commission will make the lead in solders ban optional and
NOT obligatory by their review in 2008 at the latest.



John

Subject: [LF] RoHS Opposition (on Pb) isn't sound (SMT Sep 2006)



Hi IPC LF Listservers,



For those of us who get SMT Magazine we may have already seen the September

2006 article by Dr Ron, (Ron Lasky), in SMT Magazine's Surface Mount

Process Optimization regular column. As soon as it is available on

www.smtmag.com one of us should post the link.



The title is " "Repeal RoHS" Movement Emerges", which is a bit ODD to me

for a Process Optimization column. Oh Well !!. SMT Magazine should probably

change the column title to a free flowing opinion piece.



This opinion piece by Ron is extremely negative on anyone who opposes Lead-

Free as if they are just un-informed underclass persons. Dr Ron is not

alone in this approach. In a older good book with lots of good information

from the Univ of Maryland (CALCE) the same opinion was written for anyone

who stands for sound engineering or even asks "Just Why are we doing this?"

or  "Where's the data?" . CALCE too, was not alone for jumping on the

current political band wagon.



(For reflection is a historical data point that the first emperor of China

sealed in his mercury tomb, all his chief engineers that engineered his

tomb)



Anyway, I like Dr Ron, know him personally, and Dr Ron sometimes reads this

list. Even SO for those who get the magazine let the comments begin on his

article. I will add mine a little later.



Yours in Engineering, Dave

YiEngr, MA/NY DDave



P.S. I hope a Canadian Goose was caught by RockWellC DavyH.
