Core Engineering Advantages for High-End AI Hardware
Elite High-Layer Registration & Alignment: Fabricating 20+ layer boards requires flawless precision. Our advanced inner-layer registration systems and high-precision LDI (Laser Direct Imaging) ensure perfect via-to-pad alignment across all layers, eliminating potential open or short circuits.
Minimized Transmission Attenuation: By combining ultra-low-loss resin matrices with HVLP copper foils, our high-layer boards eliminate the "skin effect," successfully maintaining exceptional signal integrity at data rates exceeding 56Gbps and 112Gbps per channel.
Ultra-Dense Routing Capabilities: Our Any-Layer HDI technology allows seamless interconnection between any layer, drastically shortening signal paths and freeing up critical space to easily handle fine-pitch BGA or flip-chip components (<0.4mm pitch).
Thermal & Structural Reliability: Designed to operate continuously under high thermal loads. Every board undergoes strict cross-section analysis, thermal shock testing, and 100% AOI to ensure long-term structural integrity in data center environment conditions.
Key Applications
Our high-layer density computing circuit boards are certified for mission-critical deployments:
- AI Accelerators & GPU Modules: OAM-compliant hardware and high-wattage computing cards.
- Next-Gen Networking Hardware: High-performance 400G and 800G enterprise switch and router line cards.
- Data Center Core Boards: High-stratum server motherboards supporting heavy-bus structures (DDR5/HBM).
- Automotive Central Computing Units: Compact, ultra-reliable HDI modules for L4/L5 Autonomous Driving Systems (ADAS).
