Internally die-referenced thermal transfer plate

Abstract

This disclosure describes an electronics device that effectively removes heat from the SoC, which increases its efficiency and extends its useful life by spreading heat in the thermally conductive plate before transferring it across the interface. Surface area is a significant factor in TIM thermal performance, so this increases the performance substantially when using the same type of TIM pad. This device allows the use of lower performance TIM pads that resolve the issues of high die pressure and non-resilient behavior of high thermal conductivity TIMs. Additionally, the device mechanically isolates the SoC from the heatsink, which reduces stress and provides improved thermal performance.
