We are having an issue with an entire lot of BME280 sensors that have been reflowed onto our design. During reflow we followed the exact recommended curve for the BME280.

This did not work for us. It seemed to only improve the sensors by 2%. Are there any other methods to reconditoning these sensors? Is there any known eratta or other issues not listed in the data sheet?
