China's tungsten curbs disrupt supply of micro drill bits used for AI chips, Nikkei Asia says
Without the tiny tools, substrate and circuit-board makers cannot drill the connections that join the parts of an AI chip package.
China's export controls on critical metals have disrupted supplies of micro drill bits, small components used in the AI chip supply chain, Nikkei Asia reported. The curbs on tungsten are what is hitting the drill bits.
The part is narrow, but it is a real choke point. Without micro drill bits, substrate and circuit-board makers cannot drill the vias, the tiny holes that connect an AI chip package. A shortage would therefore bite further down the chain than the restrictions on the GPUs themselves.
That is the larger point. The contest over AI chips now reaches raw-material inputs, not just finished hardware or software. If the disruption persists, it raises the risk of delays in AI hardware production that no export-licence decision in Washington would clear.
