Good morning Bob,
I think the fly clip would go down a storm here with the warped sense of
humour these guys have. If pos, please mail it to me...........Thanks
Best Regards

We hope the next edition of the Lead Free CookBook CD ROM will have results
of solderability trials on lead free alloys with different surface coatings.
It should also contain video clips of wetting tests which have already been
done as examples of the test only.
As a side issue the boards used in the video filming were three years old
OSP, gold over nickel and Silver using a standard test flux with very good
results. During filming the only problem we had was a fly landing on one of
the samples during test. This clip will not be on the Cookbook CD.
If any one wants the Bob Willis Solderability Fly video, goes down a storm
at technical seminars, breaks up the technical bits. The clip is only 500K
for use on PowerPoint presentations and its FREEE

Hello,
You will find, on the Multicore site,
http://www.multicore.com/default.htm <http://www.multicore.com/default.htm>
an interesting report on their lead free solder, paste and wire.
By following the lead-free links, you will reach the report
http://www.multicore.com/datasheets/msl733.pdf
<http://www.multicore.com/datasheets/msl733.pdf> in which is detailed (page
2) the wetting time of their ECOSOL lead-free solder compared to the
Sn60Pb40.
A precedent Email in the IPC lead-free forum also gave this address:
http://www.lead-free.org/ <http://www.lead-free.org/>
which contains an interesting cross table alloys/suppliers (quite
extensive). Some suppliers probably have reports as you look for (Multicore
do).
Regards.
P.S.: I have no actions in Multicore.

Objet: [LF] Solderability test results obtained with lead-free alloys
Dear colleagues,
our German standardization committee has lauched a task force to study the
influence of lead-free soldering processes to the content of existing
standards,
especially those describing test methods and evaluation critieria for
solderability and resistance against soldering heat test.
Previous investigations have shown that there will be differences in
wetting
behaviour compared to SnPb solder, which actually is used for these tests.
Has anybody already done such investigations, or has information or
links to
reports etc. ?
