Industry Insight: AI Revolution Drives PCB Expansion—High-Order HDI And HLC Capacity Become Strategic Assets
Mar 21, 2026
1. Material Evolution: The New Era of Next-Gen CCL
As of March 2026, the global PCB supply chain has entered a critical testing phase for M10, the next-generation CCL (Copper Clad Laminate) material. Driven by requirements from AI giants like NVIDIA, this marks the beginning of a massive upgrade cycle for AI server hardware.
If testing proceeds as expected, mass production for M10-based PCBs is projected to ramp up by the second half of 2027. This material evolution is essential for supporting the ultra-low latency and high-speed data transmission required by next-gen AI inference clusters.
2. Capacity Trends: High-Order HDI and HLC as the New "Gold Standard"
The 2026 expansion logic within the PCB sector is clear: High-value-add production is the only priority.
- Strategic Shift: Global capital investment is now heavily concentrated on HDI (High-Density Interconnect), HLC (High Layer Count), and SLP (Substrate-like PCB).
- Performance Gains: Manufacturers focusing on these high-frequency, high-speed sectors reported net profit surges in 2025, with some industry leaders seeing growth between 270% and 370%.
3. Beton Tech: Engineering Precision for the AI Era
To align with global Tier-1 standards, Beton Tech has synchronized its production capabilities with the latest industry benchmarks. Our facility in Shenzhen is now fully optimized for ultra-fine pitch and high-layer-count AI hardware.
Technical Showcase: 6-Level Any-Layer Interconnect (ELIC)
The image below demonstrates our advanced fabrication capability in Stacked Microvias. This 6-level structure is critical for reducing signal loss and maximizing routing density in compact AI modules.

4. Overcoming Technical Barriers: The "Secret Sauce"
The leap to 50+ layers and any-layer structures requires more than just basic equipment. At Beton Tech, we utilize:
Advanced LDI (Laser Direct Imaging): Ensuring line resolution at the 30μm level.
Sequential Lamination & Step-Drilling: To maintain structural integrity and high yield rates across complex stack-ups.
High-Performance Materials: Full compatibility with M7, M8, and M10-equivalent low-loss substrates (Panasonic, Rogers, Isola).
5. Future Outlook
While market concerns regarding material price fluctuations and application delays exist, the underlying growth logic for AI PCBs remains stronger than ever. Beton Tech continues to invest in R&D to ensure that our clients stay ahead of the curve in the 2027 mass-production cycle.
