We don't use Sn50, but if we did, we'd use our paste supplier's recommendation as the starting point for developing our reflow recipe.

Who is the paste manufacturer? They are the ones who can tell you what to run.

Hi,

I agree with everyone else talk to the Mfg and ask for their recommended profiles. They should know the heating and the cooling profiles.

If you really want to do this yourself you are going to have to run several experiments to determine just how the flux works and at what temperature. Do you need to hold it at temperature (soak) or can you ramp.

Good Luck
