You guessed right. Not hot enough to get good reflow. regards sarason

Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence o

Hi First I think you have to analize your PCB design. Heavy weight components should be gathered on one side of PCB. As I think, if you want to reflow both sides simultaneously there might be a problem. A chance that large components will drop off

I concur with your second approach. A profile needs to be tailored to the design of the board, the components, and the solder paste. Your first approach seems to try to balance lower quality soldering with a lower process complexity.
