Nvidia Works Directly With PCB Material Suppliers Amid Projected 1,500-Ton HVLP4 Copper Foil Shortfall

Industry sources say Nvidia and major customers are working directly with upstream suppliers of T-glass fiberglass cloth and HVLP4 copper foil to keep next-generation AI server production and shipments on schedule as bottlenecks deepen in PCB materials. Nvidia-led buyers are said to be bypassing traditional copper-clad laminate suppliers, providing clearer order visibility and shifting to a buyer-furnished-material model that locks in key capacity more than a year ahead.

The reported intervention points to a new choke point in AI infrastructure, with HVLP4 copper foil expected to become a key constraint from the second half onward as platforms migrate from HVLP2 and HVLP3. The 2026 HVLP4 supply shortfall is projected at 1,500 tons and could widen to 2,500 tons in 2027, while T-glass fiberglass cloth for IC substrates is also tight; Nittobo controls more than half of global capacity and the 2026 supply-demand gap is estimated at more than 40%.
