A domestic copper-foil maker said its HVLP fourth‑generation compute copper foil
for AI servers and high‑speed optical modules is booked through H2 2027.
Suppliers must move from RTF to HVLP1–2 then HVLP3–4, with each generation
needing a 6–12 month validation cycle and 1–3 years for full system‑level
certification. Buyers including NVIDIA, AMD, Intel and Huawei Ascend enforce
strict generational requirements and certify only a handful of global suppliers.
