>Michael,
>The company in question is Canada's Nortel Networks.  The work was carried
>out in Great Britain with input from Ottawa.  One hundred and fifty
>telephones were produced with tin/copper based solder paste and solder in a
>wave solder machine.  All soldering was done in nitrogen.  The boards were
>FR-4 with Entec 106A.  Some components came lead free, others were stripped
>and recoated and some were used as is.  As stated elsewhere by another
>writer, Ken Snowdon of our Harlow Lab would be the person to contact for
>more information.  Also, the Harlow lab (England) has authored a number of
>papers in the open literature you should be able to find.  Use Chris Tanner
>as your search key.  Most of these will be papers in proceedings of the IPC,
>SMI, Nepcon and the SMART group in Great Britain.

>> Chris,
>> Thank you for this information.  I do have a question you might be able to
>> answer. I have read that Japan's Nortel has built a lead-free telephone.
>> This means that the phone's PC boards have no lead in them.  Do you know
>> what they use in the place of HASL and Sn/Pb etch resists?

>> >>Dear Leadfree Subscribers:
>> >>
>> >>The IPC is hosting an international summit on lead-free electronic
>> >>assemblies from October 23-28 in Minneapolis, Minnesota.  At the summit,
>> >>the Environmental, Health, and Safety Committee of the IPC will hold a
>> >>session on Monday, October 25th from 9 AM to noon, entitled: "The
>> Problems
>> >>and Promise of Lead in Electronics."
>> >>
>> >>The session is designed to help illuminate the public policy debate over
>> >>the continued use of leaded solders in the electronic industry, focusing
>> on
>> >>the environmental risks posed by leaded solders and the environmental
>> risks
>> >>posed by possible alternatives.  It is designed to help members
>> understand
>> >>both the fact and fiction behind the debate so that members can
>> voluntarily
>> >>decide which solders will work best for their own particular
>> applications.
>> >>
>> >>As you may know, the European Union is proposing to ban the use of lead
>> in
>> >>electronic devices by the year 2004 due to concerns that, when disposed
>> of,
>> >>electronic devices will leach lead into groundwater. However, some
>> industry
>> >>representatives contend that such concerns are unwarranted or could be
>> >>addressed through other policy options, such as increased recycling.
>> >>Futhermore, there is concern that alternatives to leaded solders could
>> pose
>> >>other environmental problems.
>> >>
>> >>This session is designed to illuminate the issue so that participants
>> can
>> >>better understand the environmental impacts associated with the
>> industry's
>> >>continued use of leaded solders.  The IPC is currently soliciting papers
>> >>for this session.  Currently, the format of the session is very open.
>> >>Possible topics include:
>> >>
>> >>- the environmental risks posed by leaded solders in electronics
>> >>- the environmental risks/benefits of alternative solders
>> >>- policy options for reducing the environmental risks posed by leaded
>> >>solders (International, federal, or state)
>> >>- cost-benefit studies of leaded solders or their alternatives
>> >>- Life Cycle Analysis of leaded solders or their alternatives
>> >>
>> >>Again, the purpose of this panel will be to help clarify the science
>> behind
>> >>this issue so that the IPC members become more aware of the
>> environmental
>> >>risks associated with leaded solders and their alternatives.
>> >>
>> >>Please e-mail me directly if you are interested in participating in this
>> >>session.
>> >>
>> >>Sincerely,
