In 2026, the global heavy copper PCB market reaches roughly $614 million, up from $564 million in 2025, as EV powertrains, renewable inverters, and AI power modules drive demand. Yet manufacturers face margin pressure: copper prices have climbed about 30% year-over-year, with CCL lead times stretching to six months. The segment is forecast to expand at a 7–10% CAGR through 2033, rewarding suppliers that can secure upstream capacity.
