Context Before

For Rubin, the heat spreader lid is a module made up of two separate lids.

Evidence

Beside the heat spreader lid, a stiffener is added to the package structure to provide even more mechanical support to avoid warpage.

Context After

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.

② Atomic Claim

除了 heat spreader lid 之外，package structure 也加入 stiffener，提供更多 mechanical support 以避免 warpage。
