1. First- pls give a name and contact information with notes so 
that replies can be sent to you directly, which is often faster 
than posting them on the TechNet.
2. You will probably get lots of information on potential sources 
of sulphur contamination- such as packaging cartons etc. made by 
the Kraft process, but one that is not often obvious is the 
storage of PWBs and components near the employees cafeteria.
Enterprises that serve breakfast in their canteens often cook 
eggs...and the resulting sulphur in the air ends up on the PWBs.
Not obvious--- but it has happened.
