The Groq 3 server racks, expected to ship in the second half of 2026, will contain 256 Groq LPUs across 32 compute trays, interconnected by complex 52-layer circuit boards. Each rack's PCBs require 384 sheets of Q-Glass Copper Clad Laminate, valued at an estimated US$120,000 per rack for the CCL alone. Demand for these servers is projected to be between 12,000 and 13,000 racks across 2026 and 2027.
Groq's server design highlights the extreme material and manufacturing complexity of next-gen AI compute, driving demand for specialized high-layer PCBs and advanced laminates.
