Hello, I will be performing a study on the temperature profile design in the reflow ovens (forced convection) of our SMT lines. Currently they are set up in the traditional 4 zone profile (soak zone included.) Has anyone switched to a 'ramp profile' (eliminated the soak zone) ? What were the benefits seen with this new profile design? What is the general opinion in regard to using a ramp profile? Thanks! Kate Bishop Process Engineering Leitch Technology Int.
