Not sure I worded this question so will ask again a slightly different way as I didn't get any responses.



If one is reflow soldering ENIG boards with a mixture of SnPb & PbF part (in particular PbF BGA's - SAC305) using a 63/37 SnPb solder what would be the preferred peak temp / time above?



Regards,

	Iain.

Joyce,



I can't say it is preferable but how does one solder a board using SnPb solder with the odd PbF part whilst trying to ensure the profile will provide sufficient time above Solidus (Werner see I've learned!) to enable a satisfactory soldered joint?



Regards,
