AI Servers Are Eating Thai PCB Capacity

Nvidia-tier suppliers operate at 100% utilization while non-AI fabricators run at 50%. The bifurcation is shaping which Thai factories survive the next 18 months.

The global PCB market is entering a structural growth phase driven by AI infrastructure. Output value is projected to reach USD 92.36 billion in 2025, up 15.4% year-on-year, climbing to USD 105.2 billion in 2026. Hyperscale operators deployed roughly 1.2 million AI-optimized servers in 2025, each integrating 8-16 GPU accelerators that specify 40-to-60-layer backplanes priced above USD 200 per board.

Thailand sits at the crossroads of this build-out. Victory Giant Technology, Nvidia's leading PCB supplier with a market capitalization of USD 32.6 billion, acquired APCB's Thailand business in 2024 and is rapidly equipping a second Ayutthaya factory. Gold Circuit Electronics, Taiwan's largest server PCB manufacturer and a key Nvidia supplier for networking switch trays, runs its first Thai facility at full capacity, with a Phase 2 expansion targeting ASIC server capacity by H2 2026.

A two-speed market emerges

Taiwan Institute of Economic Research analysts caution that many newcomers have built only one to two production lines so far. Non-AI demand is uncertain due to US tariff policy. Dingying Electronics Thailand reported only 50% capacity utilization in Q1 2025; Shanghai Electric Power (Thailand) suffered a RMB 51 million loss in the same period. Only AI-linked suppliers, VGT, GCE, have secured clear demand pipelines.

The split has procurement implications. Buyers chasing AI-grade boards face allocation, premium pricing, and waiting lists at the AI-tier suppliers. Buyers running consumer or industrial boards face the opposite: spare capacity, hungrier sales teams, and aggressive terms from underutilized fabricators looking to fill lines.

HVLP4 copper foil is the new bottleneck

Hyper Very Low Profile Generation 4 copper foil, required for AI server signal integrity at 56 Gbps, is in structural global shortage. Processing fees have reached USD 25-30 per kilogram, with demand expected to remain strong for 2-3 years. Thai PCB factories making AI server boards compete with global buyers for limited HVLP4 supply from Japanese mills (JX Nippon, Furukawa) and top-tier Chinese producers. The global copper foil market is further constrained by J.P. Morgan's projected 330,000-ton refined copper deficit for 2026.

“All high-end materials still need to be imported, adding transportation and warehouse costs. The Thai cluster is very much like China 20-30 years ago.”

The localization timeline

Until Panasonic's MEGTRON facility reaches operations in November 2027 and Doosan's AI-grade CCL plant ramps in H2 2028, AI-grade laminates remain import-dependent. The window between 2025 and 2027 is the procurement opportunity: AI-tier fabricators must secure imported supply through alternate channels while their captive material vendors complete Thai capacity additions.
