Hi all,

I need to find some written data on the long term reliability of rohs 
assemblies.  We don't have comply with rohs but can only get the 
parts in rohs, with BGA's being the main drive for rohs compliant solder.

Just had an assembly vendor say that a rohs bga can be assembled with 
eutectic solder paste with good results.  2 other assembly shops say 
that is not recommended.  Is there any real studies or data available 
that provides the real answer?  Also studies and data for the 
reliability of rohs?  We need our boxes to work for 10 years or more.

Thank you for your time.   What a great network for people to share 
knowledge.  I will also be going through PCD&F and google to 
(hopelessly behind on my reading)
