Power the Future of Computing: UGPCB’s High-Performance Server PCB Solutions

In today’s rapidly evolving landscape of data centers, искусственный интеллект, and cloud computing, server performance and stability are pivotal to digital efficiency. As the fundamental hardware bedrock, the quality of Server Печатные платы (печатные платы) is paramount. Leveraging deep technical expertise, UGPCB предоставляет профессионал, customized, high-performance server PCB manufacturing and печатная плата (Печатная плата в сборе) one-stop solutions.

1. Обзор продукта & Определение

A Server PCB is a complex, multi-layer circuit board specifically engineered for server-class products. Its critical mission is to host core components like CPUs, память, high-speed buses, and power modules while ensuring stable signal transmission at speeds of tens of Gbps and beyond. It is not merely a physical connection platform but the core element guaranteeing the system’s signal integrity, целостность власти, and thermal performance.

The specifications you provide (Толщина доски: 2.8mm ±10%, 22 Слои, 2/1 oz Copper Weight, 0.1/0.1 mm Trace/Space) define a typical high-layer-count, высокая плотность, high-speed server PCB. It is suitable for critical applications in mid-to-high-end dual-processor or AI server motherboards, accelerator cards, and backplanes.

2. Design Essentials & Key Technologies

The success of such advanced Проекты печатных плат hinges on mastering a range of cutting-edge technologies:

  1. Stack-up & Контроль импеданса: The complex 22-layer stack-up requires precise calculation to achieve strict контроль импеданса (typically 50Ω single-ended, 100Ω differential), forming the cornerstone of Высокоскоростной дизайн печатной платы.

  2. Назад бурение: This critical process removes the unused copper stub from high-speed signal vias (например, for PCIe, DDR buses), significantly reducing signal reflection and attenuation, and is central to enhancing signal integrity.

  3. High-Speed Laminate Application: We utilize premium high-speed materials like IT-968G & IT-180A from ITEQ. Their low dissipation factor (Дф) and stable dielectric constant (Дк) ensure signal purity and low latency. A high Glass Transition Temperature (Тг >170°С) guarantees material reliability under the prolonged high-temperature operation of servers.

  4. РТФ (Reverse Treated Foil) Медь: Its smoother surface profile effectively reduces “skin effect” losses for high-frequency signals on the conductor surface, further enhancing high-speed performance.

  5. Any-Layer HDI & Hybrid Construction: Supports high-density routing. Combined with hybrid construction techniques, it allows the use of different performance materials in localized areas (например, high-current power zones vs. high-speed signal zones) to meet specific circuit requirements.
