the temperature rises +3c to 5c, so chose the x3 setting according to your jovy machine errors (how much the temp spikes after the profile is completed).
Do not move the upper heater to parking mode after the profile is completed, wait for five to seconds then move the upper heater to parking mode while reflowing. when removing the IC move the upper heater immediately after removing the IC.
this profile settings are working for me , pls work on junk boards and check the profiles efficiency & do not blame me if it fails, i am just trying to help you.

I burnt one board already with Jovy now i have found your profile & will use it. I am sure to get result. Can you please tell me if I should add Flux before starting preheat or after the preheat is complete. Thanks
