We give our customers boards with no finger prints and we don't need gloves to do it. 

We provide gloves to final inspectors who they feel the need to use hand cream. 

Here to the with or without gloves touch only the sides of the board and any defect arrow is applied with tweezers.

Kevin, 
Our scare tactic is the CUSTOMER, they say "no fingerprints" we give 
them no fingerprints! We wear gloves at every step of the process.

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!
