Context Before

At CES 2026, Jensen mentioned that with the streamlined cableless design and automation assembly process, compute tray assembly time has significantly reduced from 2 hours to 5 minutes from Blackwell to Rubin. There are only three L10 level compute tray assembly partners with automation capability for the Rubin platform—Foxconn, Quanta, and Wistron.

Evidence

At L6, board level PCBA, Wistron and Foxconn are the main supplier of Blackwell and Rubin.

Context After

For L10, Blackwell had lots of different compute tray manufacturers as they buy the Bianca boards from Nvidia to sell to their clients. For Rubin, there are only three suppliers that have the capability to do automation of Rubin compute tray. For smaller ODM or OEM, they either have their compute tray made at the three automation suppliers mentioned above or they will do it in-house without automation.

② Atomic Claim

在 L6 board-level PCBA 階段，Wistron 與 Foxconn 是 Blackwell 與 Rubin 的主要供應商。
