Shares related to printed circuit board (PCB) manufacturing are experiencing a collective uptrend.

At the time of writing, KB LAMINATES (HKEX: 01888)

was up 7.13% at HK$5.305, while KINGBOARD HLDG (HKEX: 00148)

gained 3.15% to HK$6.225. VGT (HKEX: 02476)

rose 3.73% to HK$4.228, and DELTON (HKEX: 01989)

advanced 2.97% to HK$1.70.

Catalysts for the Movement

The move follows news that major copper-clad laminate (CCL) suppliers, including Kingboard, have begun issuing price increase notices for the third quarter.

The hikes, generally in the range of 10% to 15%, mark the second industry-wide price adjustment this year, following an 8% to 10% increase implemented in March.

Notably, one producer has raised prices seven times since 2025, primarily driven by tight supply and rising costs of upstream raw materials.

Analyst Perspective on Growth

Analysis suggests that the AI PCB supply chain is accelerating its procurement activities in the second quarter of 2026.

The release of new production capacity to meet orders for next-generation AI server platforms is expected to support a continued trend of strong quarter-on-quarter earnings growth.

From a longer-term viewpoint, the PCB industry chain is innovating across multiple dimensions, including new materials and technologies, to address challenges in AI data centers such as the need for faster signal transmission, higher integration, and improved thermal management.

These advancements are anticipated to unlock significant future growth potential for the sector.
