Context Before

Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗

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

For Rubin, the heat spreader lid is a module made up of two separate lids. Beside the heat spreader lid, a stiffener is added to the package structure to provide even more mechanical support to avoid warpage. At the surface of the heat spreader lid, there will also be a layer of electroplated gold. The reason for this is to prevent corrosion from liquid metal TIM2, which is between the heat spreader lid and the cold plate.

⑥ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
