In the first half of 2026, more than 20 Chinese printed circuit board makers disclosed capacity expansion plans as demand rose for high-end boards used in AI servers, a push that could take sector capital spending to a record high.

Huizhou-based Victory Giant Technology, a PCB manufacturer in Guangdong province in southern China, raised first-quarter capital expenditure to 3.6 billion yuan (US$530 million) from 730.1 million yuan (US$107 million) a year earlier.

Kunshan-based WUS Printed Circuit, a PCB maker in Jiangsu province in eastern China, more than doubled spending to 1.5 billion yuan (US$221 million) from 658.1 million yuan (US$96.8 million).

The surge was driven by a shift toward the high-end boards required for AI servers.

These PCBs can require 18+ layers, use 4–8 step HDI (high-density interconnect) structures, and rely on high-frequency, high-speed materials.

China already makes six of 10 PCBs globally, increasing the potential supply-chain impact of the factory build-out.
