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

In today’s rapidly evolving landscape of data centers, inteligência artificial, and cloud computing, server performance and stability are pivotal to digital efficiency. As the fundamental hardware bedrock, the quality of Server Placas de circuito impresso (PCB) is paramount. Leveraging deep technical expertise, UGPCB provides professional, customized, high-performance server PCB manufacturing and PCBA (Conjunto da placa de circuito impresso) one-stop solutions.

1. Visão geral do produto & Definição

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, memória, 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, integridade de energia, and thermal performance.

The specifications you provide (Espessura da placa: 2.8mm ±10%, 22 Camadas, 2/1 oz Copper Weight, 0.1/0.1 mm Trace/Space) define a typical high-layer-count, alta densidade, 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 Designs de PCB hinges on mastering a range of cutting-edge technologies:

  1. Stack-up & Controle de impedância: The complex 22-layer stack-up requires precise calculation to achieve strict controle de impedância (typically 50Ω single-ended, 100Ω differential), forming the cornerstone of design de PCB de alta velocidade.

  2. Back Drilling: This critical process removes the unused copper stub from high-speed signal vias (por exemplo, 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 (Df) and stable dielectric constant (Dk) ensure signal purity and low latency. A high Glass Transition Temperature (Tg >170°C) guarantees material reliability under the prolonged high-temperature operation of servers.

  4. RTF (Reverse Treated Foil) Cobre: 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 (por exemplo, high-current power zones vs. high-speed signal zones) to meet specific circuit requirements.
