Chris,
Congratulations on your successful weekend, now the fun really starts with
a whole new life ahead of you. I contacted the product manger of MS2 who
is a friend of mine and and asked him to contact you. Hope he does this
real soon.

Hello all,
I am here and I have survived... I have been blessed with a positive answer
- that being YES! We spent a wonderful 2 days at an 130 year old mansion
being pampered to death and eating tasty food to boot! The night went
perfectly with a 6 course meal with the 3rd course being served in a
vintage serving tray with the ring wrapped around a white tulip by our own
personal 1800's vintage server. This is when the crying started and I
started my spiel on one knee. After the crying had ceased (for 3.68
minutes) and asked her for her hand in life she said yes. So thank you all
for your words and now I am considered a fiancé as well as a future husband
to a wonderful young woman.
Thank you very much - it is nice to know that you all are not only an
excellent resource for the industry, but for life as well. God Bless...
As far as George's concerns - I have similar ones when I started the
investigation into this fluid. I have requested ALL quality documentation
from this manufacture as well as all test data (long and short) to aide me
in the qualification of the material into our processes. The requests were
made in November of 05 and I have yet to receive anything, even after a
second request. So maybe they just don't have the information, have the
information but it is inadequate, or forgot all about my requests
altogether.
So where does the oxidized material reside within the solder - these things
do not just up and disappear. If they are broken down but not out, then are
they suspended somehow so they do not come into contact with the CCA's
metallurgy during soldering (unlikely) or are these "byproducts" now part
of the solder thus part of the solder joints on the CCA?
Don't know... I'm sure that some of the metallurgy experts within these
rooms might better answer these questions.

First off, I hope all went well for Mr. Schaefer last weekend and hope to
hear a positve verdict.
I got to thinking last weekend (dangerous and smokey) and having seen the
material at APEX and observed the dross and surface tension reduction, I
was impressed. BUT, what are the breakdown or oxidation byproducts and can
there be any trace incorporation of this liquid organic into the molten
solder itself. If it is, does this tend to create a compressive stress and
facilitate the generation of whiskers? I would tend to think there would
be no miscibility at all but i would like the thoughts of more
metallurgically educated minds than mine.

Subject: [TN] Solder Surfactants in the solder pot
Hello all,
Has anyone within these walls used the newer flavors of solder surfactants
or is considering using them in their solder pots for wave? Since the cost
of Lead Free solder is so high and the dross production will be
significantly greater, we have been considering the use of this material to
reduce dross production thus reducing costs. There is a brand name called
MS2 technologies which is distributed through or made by PK Metals. There
is a material for Pb free soldering and Pb soldering depending on what you
are using. I have ordered some of this liquid material to determine the
effect it has on dross production and other components of flow soldering
(i.e. joint integrity, affects on the metals inside the solder pot,
increased or decreased wetting ability, and quite a few more components).
So if anyone has some insight into the new solder surfactants, I would
appreciate you help and guidance.
Thank You in advance and hope you all have a great weekend. I know I will
(maybe... hmmmm!) because I am proposing to my girlfriend this weekend -
hopefully she say's yes - I need all of you prayers ha ha! Chow!
