On May 27, PCB and laminates leader Kingboard Laminate announced another price hike – the second this year. The company will raise board prices by 10% and PP prepreg by up to 20% , effective immediately. The increase is driven by rising copper prices, tight glass fabric supply, and overall raw material cost pressure.

In April, Kingboard had already raised board and PP prices by 10%, citing resin and glass fabric shortages. The repeat increase highlights sustained material tightness in the PCB upstream.

Copper foil prices are already up 30% year‑to‑date . Overseas material giants have also moved: Japan’s Resonac raised copper clad laminate and bonding film by over 30% effective March 1. On April 1, Mitsubishi Gas Chemical ( >50% of global BT resin market) raised copper clad laminate and related materials by over 30%. BT resin‑based copper clad laminates are critical for AI chip packaging substrates.
