Rick,
Although the IPC LF and TN Forums weren't set up to question the logic
of governments, they were set up as you indicate to share
non-proprietary technical knowledge. IPC and the standards that they
generate have always been "Data Driven". I for one have to applaud John
Burke for setting up his Pushback web site and for trying to get the
technical participants on the IPC forums to share and collect their
technical data to put some sanity into the Pb-Free arena and begin to
let decision be made based on data.
Regards,
George

What do ya'll say we kill this email thread? Other people have access to
this forum and IPC did not really set it up to question the logic of
government forced LF, but instead to help each other in the industry as
we stumble thru the process by distributing non-proprietary technical
knowledge to help us with implementation issues.. :<

Hello Keith,
Although the word "Reliability" is not specifically used, the RoHS
directive (2002/95/EC) does cover this aspect under Article 5
"Adaptation to scientific and technical progress".

ref you statement:
"Regarding the reliability issue, the use of lead in solder in
applications where reliability has been identified is an issue is either
exempt or is currently the subject of a request for exemption. I
understand that these exemptions will remain in place until there is
evidence that the alternatives are reliable."
where is this stated in the directive or SI for RoHS other than
infrastructures etc.

John,
I don't pretend to be an environmental expert but if you read the WEEE
Directive you will see that the objective of the RoHS Directive is to
remove hazardous substances in order to enable the management of the
recycling and recovery of Waste Electrical and Electronic Equipment, one
of the most rapidly increasing waste streams. This will have a positive
impact on all of the environmental areas you quote as being impacted by
change-over to lead-free solder.
Regarding the reliability issue, the use of lead in solder in
applications where reliability has been identified is an issue is either
exempt or is currently the subject of a request for exemption. I
understand that these exemptions will remain in place until there is
evidence that the alternatives are reliable.
Regards
Allen

Good morning electronics industry!
For all of those people out there who cannot understand WHY we are
removing the lead in solders I have put up a web site as both a
discussion as well as an informational forum.
It makes some points and provides a feedback vehicle for those among us
who feel that it was not necessary and actually may be environmentally
detrimental.
And whether you agree with it or not please take the time to read
through it - the feedback is valued. If you like it, pass this email
along to your Colleagues.
Here is the link:

Kind regards,
John
