Werner ,
 
I understand the issues around not achieving a homogenous joint ie. >217C that is why I ran a profile peak of 232ish, which I would have thought would have been enough to provide a good joint but not high enough to cause problems with packages that are not rated for PbF.
 
Regards,
    Iain.

Hi Iain,
For a mixture of SnPb & PbF part (in particular PbF BGA's - SAC305) using a 63/37 SnPb solder, the preferred reflow profile is definitely a LF-SAC profile, NOT a SnPb-profile.

Werner
