Context Before

For the mechanical structure of the Rubin package, upgrades have also been made with the addition of an upgraded heat spreader and a stiffener. This compares to Blackwell B200 and B300 packages that only have a heat spreader lid. The heat spreader lid allows more equal distribution of heat exiting the package. It also provides mechanical support for the package to prevent warpage.
Evidence
The reason for this is to prevent corrosion from liquid metal TIM2, which is between the heat spreader lid and the cold plate

Vera
② Atomic Claim
此設計是為避免位於 heat spreader lid 與 cold plate 之間的 liquid metal TIM2 造成腐蝕。
