(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application

report.

(2) JEDEC standard JESD51-X specifies this measurement at the center position on the top surface of the package. Due to the location of

the cavity opening at the center position, this measurement is not applicable.
