AI infrastructure bottlenecks shift back to leading-edge capacity and CoWoS packaging

Supply chain constraints for AI infrastructure have reportedly shifted back to leading-edge foundry capacity and CoWoS advanced packaging availability, rather than power supply. Additionally, the PCB manufacturer Meiko Electronics is noted to have limited exposure to the AI GPU market.
Context
The AI infrastructure landscape is facing a critical supply-side shift as bottlenecks move from power availability back to leading-edge logic capacity and CoWoS packaging. Analysts report that TSMC 3nm and 2nm wafer demand is currently outstripping supply by nearly three times, a gap expected to persist through 2027. While earlier constraints focused on data center power, the current squeeze is defined by the inability to fabricate and package high-end GPUs and ASICs fast enough to meet hyperscaler demand.
Major players like Nvidia, AMD, and Google have reportedly booked out TSMC's CoWoS capacity through at least mid-2026, forcing secondary vendors to seek alternatives like Intel’s EMIB and Foveros packaging. While companies like Meiko Electronics are integral to the high-end PCB and substrate supply chain for AI servers and smartphones, their direct exposure to GPU-specific packaging bottlenecks remains limited compared to Tier-1 foundry and OSAT partners. This structural tightness is driving a transition toward a fragmented backend ecosystem as firms prioritize domestic packaging pathways to bypass Taiwan-centric capacity limits.
