Hi Phil,

The intermix between SAC305 and SN100C is fine. An article that
discusses this is available at

Best regards,

Subject: [TN] mixing lead-free solders

Good afternoon,
 
As we move further into LF conversion I was curious what you, the gurus
of TechNet, thought about the possibility of mixing LF solder alloys.
 
We are converting our manufacturing operation to SAC 305 for wave and
hand solder.  We have a CM that is using Sn100C in their wave.  There is
the potential to have to manually repair a board built with Sn100C by
hand soldering with SAC 305.  Are there any reliability issues with
this?  Assume the board will be properly cleaned after soldering.
 
I haven't looked into our SMT CM and their process, but it could be
similar.
 
I'd hate to have to run three or four lines to keep each alloy separate.
As it is I must manage Sn/Pb and SAC 305.
 
Thanks in advance.
 
Phil
