Have you contacted Cobar? They should have a sample of your batches of pasta they could analyse.

Keep in mind you'll still need to preheat the assembly to properly activate the flux/drive off volatiles in the paste. Perhaps a convection toaster oven... Add some cooling coils and a freeboard/tube to the top of your pasta cooker or turkey fryer t

Evtimov The areas analyzed are a standard oven curve according to the pasta we are using. The channels used are only for measuring the oven temperature profile, not in detail of the QFN component sector.

Evtimov thank you very much for sharing this profile, we will perform tests with this curve to see behaviors in the oven and pasta.

hello Evtimov Thanks for your answer. I will analyze the curve with our pasta supplier to reconfirm if it is adequate. It would also be helpful if you could share the tin lead curve profile to analyze. The location of the QFN is assembled by the top

Hi, Yes, all you really need to do is boil the fluid while suspending the PCB above the vapor, so it's quite easy. However I would recommend against dropping the board direct into the vapor cloud, as that would be a very fast warm up, while letting
