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.
regards,
Bev Christian
Manager, Materials Engineering and Environmental Lab

> >>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.
