PCB Material Update | September 2026
Cost pressure is building again across the PCB supply chain.
Copper remains near historic highs, while electronic glass cloth, copper foil, CCL and prepreg continue to face tighter supply and further price adjustments. On August 28, Kingboard announced a 10% increase for its full range of FR-4 laminates, with some thin-glass prepregs rising by 20%.
The pressure comes from more than copper: limited glass-fabric availability, higher resin, energy and logistics costs, and strong demand for high-speed materials from AI and data-center projects.
The actual impact will vary by material grade, layer count, copper weight and stack-up. For upcoming projects, earlier forecasts and material confirmation can help manage both cost and lead time.
At Yuwei Electronic, we will continue monitoring the market and providing transparent, practical sourcing support.
