Edge Computing Motherboard PCB Assembly: Ultra-Dense, High-Speed Design for AI-Driven Infrastructure
Our 12-layer HDI PCB assemblies are engineered for edge computing applications requiring PCIe Gen5 (32GT/s), 100Gbps Ethernet, and AI accelerator integration (e.g., NVIDIA Jetson AGX Orin, Intel Xeon D-1700). The 0.3mm pitch BGA routing and laser-drilled microvias (<50μm) enable 12,000+ I/O connections in a compact 240mm x 180mm form factor, reducing signal integrity losses by 40% versus standard 8-layer boards.
High-Speed Performance
- PCIe Gen5 Signal Integrity: Embedded capacitance layers and differential pair routing maintain <10dB insertion loss up to 16GHz, passing IEEE 802.3ck compliance.
- 100Gbps Ethernet Support: QSFP-DD cage integration with pre-emphasis/equalization ensures BER <10⁻¹² over 100m OM4 fiber.
- AI Accelerator Optimization: Thermal via arrays under BGAs reduce junction temperatures by 15°C for NVIDIA Orin’s 170W TDP.
Industrial-Grade Reliability
- Extended Temperature Range: -40°C to +85°C operation validated via HALT (Highly Accelerated Life Testing) with 1000 thermal cycles.
- IP67 Conformal Coating: Parylene-C layer provides 15-year corrosion resistance in humid/dusty environments (e.g., smart factories, outdoor 5G base stations).
- Shock/Vibration Resistance: Underfill epoxy for BGAs and rigid-flex connectors withstand 50g peak acceleration (IEC 60068-2-64).
Manufacturing & Compliance
- 7-Day Expedited Build: From DFM review to 1000-unit production, including X-Ray/AOI inspection and functional testing (e.g., PCIe link training, BIOS validation).
- Certifications: IEC 61000-4-6 (CSA), FCC Part 15, CE, RoHS, ISO 9001:2015.
Ideal For:
- Industrial AI (predictive maintenance, robotics)
- Smart city infrastructure (traffic management, surveillance)
- 5G edge servers with low-latency processing
