Subject: [TN] Gloved Hands / Fingerprints / Failure Articles

Hello everyone,
 
We are in the midst of a proposal from myself and manufacturing engineering
to require use of gloves or finger cots throughout our PCB assembly process.
We had considered that it really would only be required after final
cleaning, but for uniformity would require it all steps including
population.  We have of course met with a real resistance, particularly from
the final assemblers who are stating it doesn't matter once the conformal
coat is on.  I can see at least some logic in that, and admittedly a large
portion of our argument is aesthetics (we don't want fingerprints on the
boards even after coating), but it would be really nice to have some sort of
scare tactic, like an article or something that related a PCB failure to
fingerprints or handling contamination.  Anyone have such a thing?
 
Thanks!
