Global High-Density Interconnect (HDI) PCB Market Opportunity – Rising Adoption of Electric Vehicles and Autonomous Driving Technologies

The fast transition to electric and autonomous vehicles presents a big growth avenue for HDI PCBs. These boards offer high wiring density, heat resistance, and electrical reliability, supporting compact control units, ADAS sensors, and battery management systems needed for EV performance.

As automakers add more electronics to vehicles, HDI PCBs are very important for handling high-speed signals and complex power circuits. Tesla’s Model 3 and Model Y production lines have begun incorporating Meiko Electronics’ high-layer HDI PCBs for power control and sensor modules, boosting reliability and space efficiency in EV electronic systems.

Analyst Opinion (Expert Opinion)

• The industry is seeing a rise in raw material costs, especially high-performance laminates like Rogers PTFE and Megtron 6, which have eroded profitability even for large-scale manufacturers. Unless supply chain stability improves and material innovations become more cost-accessible, smaller fabricators will continue to find it difficult to stay competitive.
• Despite its advantages, HDI fabrication remains capital- and precision-intensive, demanding advanced laser drilling, sequential lamination, and strict quality control. Many mid-tier PCB manufacturers do not have the technical infrastructure needed to scale efficiently, making a bottleneck that could affect market expansion in the next few years.
• The market’s high dependence on China, Taiwan, and South Korea for both material sourcing and fabrication makes it vulnerable to geopolitical risks. Western OEMs’ efforts to localize production are commendable but far from sufficient—true regional diversification remains a long-term challenge that the industry has yet to solve.
