Copper-clad laminates (CCLs) can contribute to over half of PCB costs, and copper makes up most of the cost of CCLs. In Q2, CCL vendors issued price increase notices ranging from 5% to 10% to PCB makers, and an additional wave of price hikes is on the horizon. PCB manufacturers have bolstered safety stocks to minimize increased CCL costs, while customers are pulling in PCB demand to reduce the impact of material price increases.
