Dear All,

After wave soldering we clean our lead free boards with Iso Propyle Alcohol 
(IPA)even though we use a no clean flux. The boards are immersed in IPA tank 
and cleaned.Recently we are wittnessing white patches on the board after this 
cleaning process. How can I eliminate the white patches. Is there any 
alternate cleaning method available. Advance Thanks for the help.

Badri
