Ibiden SUPPLY CHAIN TRACE

MATERIALS🇯🇵 Japan · 4062 · TSEChokepoint

Ibiden is the world's leading supplier of FC-BGA substrates — the high-density boards that connect AI chips to server motherboards — and one of the least-visible but most consequential bottlenecks in the AI supply chain. Running at full capacity with an 18–24 month backlog, Ibiden's constrained output directly limits how fast AI server production can scale. NVIDIA is believed to hold priority allocation agreements that give it first access to Ibiden's supply.
