Hi Every One.

I need information on Migration

Question
1.  What will cause Electrical Migration

Reason :

We are seeing Dendritic Migration between components

As of now we are applying conformal coating trying to stop the migration.  

Question:

1. Is there a rework to prevent this condition.

2.  Any study or data out there on reliability as far as using this method 
to stop the migration.


Any information at all will be greatly appreciated.
If more information is needed please ask.  This is all I know as of now
I will do my best to get what ever is needed.
