Good morning all,
My esteemed colleague, Dave Hillman, reminded me that I had not turned
Technet back on after some recent travels to the UK and people had some
questions regarding the status of the paper I am (still) working on with
regards to the effects of sanitizers and lotions. I checked over the
archives to see what I missed. I apologize if people thought it would be
in the IPC Midwest proceedings. It is still in progress. The intent was
to publish for Apex 2010.
I asked the IPC if they were still accepting abstracts for Apex 2010 and
was told they were, even though it was past their previously published
deadline. So I submitted the abstract, with rosy dreams of Best Of
Conference Paper, lauds and accolades and all the other silly crap that
goes through my head when I have had too much Diet Dew.
My paper was rejected by the Apex committee........... because it was
turned in after the deadline. Duh. So, they want to know if I would do
it as a Poster Session. Hell no, the work is too good for a poster
session. I am currently on "backup status" in case someone backs out of
the conference. Did not leave a good taste in my mouth.
Anyway, I am still working on the paper, though it is nearing completion.
All the testing is done. First lesson learned: never tell anyone else
in the corporation that you are doing such a study. You get bombarded
with requests to test "my favorite brand", "I like the smell of this one,
can you test it?".
I have concluded that the hand sanitizers are not an issue. They do not
significantly transfer to the substrate and I saw no significant
degradation due to the sanitizers. I looked at 3 that were essentially
62% alcohol and 1 that was non-alcohol based. The current raging debate
here is whether to allow the sanitizers out on the manufacturing floor,
which I don't want, preferring to keep them in the lavatories. With 16
confirmed H1N1 deaths in Iowa to date (2 yesterday), we have people who
would be putting this on every 10 minutes if we let them. The second
raging debate is whether those great big plastic dispensor jugs constitute
an ESD hazard. I wish I had not opened this can of worms.
The jury is still out on the lotions. I do see some degradation of
dielectric strength, SIR, and lap shear strength for adhesion (saw some
improvement though in some cases), but not a great deal.
Keep in mind that we do still have a final cleaning step prior to
conformal coating. After that cleaning, everyone is required to wear
gloves, negating the effects of hand contact. Now I am waiting for
someone to ask the question of whether they can put hand sanitizer on the
glove surfaces. Hillman, don't you dare............
I expect to have the paper finished sometime in early December. I have
some upcoming travel (i.e. plane/airport/hotel room time) so may be able
to finish earlier. I will post the executive summary of the paper to the
forum in advance.
