Jim,
There is more at stake than just solderability.  Finger salts and oils can
create corrosion and metal migration problems when mixed with the humidity
in the air.  In addition, you can have problems with conformal coat
adhesion because of hand oils, especially if you use those anti-static hand
lotions.  We don't worry about it too much at Rockwell because all of our
boards go through a cleaning prior to conformal coating.  But, as we
transition to no-clean assembly, we know that handling will be a issue an
we will have to train our operators to work on an "edges only" basis.
