(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application
report, SPRA953.
(2) The thermal data is based on JEDEC standard high-K profile – JESD 51-5. The copper pad is soldered to the thermal land pattern. Also,
correct attachment procedure must be incorporated.
