Hi all,
 
We recently had a number a failures on MOSFETs and set samples for
analysis.  The analysis from the supplier said that some chemical
contamination occured and it's related to an halogen subtance.  
 
Can anyone tell me in a board fabrication process where such a
contamination occur?  Are fluxes containing halogen substances, cleaning
products etc.
 
Thanks in advance!
