PROFILING AN OVEN
20200248965 · 2020-08-06 · ·

Examples are described for predicting a thermal profile of a product in an oven using temperature measurements for each zone of the oven. An example method of producing a predicted thermal profile of a product in an oven includes measuring the temperature of each oven zone using a zone temperature sensor as the product transitions through the zone, and calculating the predicted thermal profile of the product using a baseline temperature profile and the measured temperatures of each zone at the time the product is in each zone. Parameters of the predicted thermal profile may be compared to thermal targets corresponding to a process specification for the product in order to determine whether the product was processed according to the process specification.
