I have a customer who is concerned about Ionic contamination due to
bromines/bromides. I have explained to the customer that the flame
retardant in FR-4 material is based on bromine. Also, the flux that we use
for the HAL is Hydrobromic Acid based, this is used instead of Hydrochloric
Acid based flux to cut down on the chloride contamination.

If anyone has information concerning this subject, I would appreciate any
and all information. I can be contacted at:
