These are precision resistors definitely plated with SAC305 - ... it's in 
the suppliers spec and in their part numbers, and we have talked with them 
about it.


Good feedback so far, thanks everyone.   If there is more feedback, I'd 
appreciate it.


Regards,

David Fischer

Subject: [TN] SAC Plated Passives with SnPb Solder Paste

Good Day,

I am aware of the nuances of mixing SAC solder ball BGA's with SnPb solder
paste, but are there any concerns, cautions or steps to take when 
soldering
SAC plated passives (chip resistors, chip caps) to a PCB using SnPb solder
paste? 


Thanks,
