Following is posted for one of our clients:

"I have a vendor that has installed a closed system conformal coat spray
machine in the middle of an area where surface mount and through hole
processing occurs.   The coating being used is silicone based.  I'm
concerned about silicone contamination of other materials in the work area,
due to unintentional migration (overspray in the atmosphere, fumes/gasses
from curing process, etc.) over time, that could affect the soldering
processes.  Are there any specifications or guidelines for SR coating
controls in a printed circuit board assembly house?  Is this a valid
concern?  Does anyone have a good or bad history of a similar situation?"

Thanks for inputs anyone has. Jack
