Evidence

This compares to Blackwell B200 and B300 packages that only have a heat spreader lid

Context After

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.
