I agree you are too cold for the profile get it up to 230C and possibly allow it to dwell a little longer in preheat as opposed to pushing up the reflow zone only. Sn90/Pb10 melts at 220C so 2C hotter than your profile so you are reliant on it alloyi

This is the dilema during this transition period. Here is a tip: If you see typcial solder joints on a lead free process, but only on one component type....it probably has a significant quantity of lead in it (ex. Sn90/Pb10...and so on) If using T
