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

In today’s rapidly evolving landscape of data centers, intelligence artificielle, and cloud computing, server performance and stability are pivotal to digital efficiency. As the fundamental hardware bedrock, the quality of Server Cartes de circuits imprimés (PCB) is paramount. Leveraging deep technical expertise, UGPCB fournit un professionnel, customized, high-performance server PCB manufacturing and PCB (Assemblage de la carte de circuit imprimé) one-stop solutions.

1. Présentation du produit & Définition

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, mémoire, 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, intégrité de puissance, and thermal performance.

The specifications you provide (Épaisseur du panneau: 2.8mm ±10%, 22 Calques, 2/1 oz Copper Weight, 0.1/0.1 mm Trace/Space) define a typical high-layer-count, haute densité, 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 Conceptions de PCB hinges on mastering a range of cutting-edge technologies:

  1. Stack-up & Contrôle de l'impédance: The complex 22-layer stack-up requires precise calculation to achieve strict contrôle d'impédance (typically 50Ω single-ended, 100Ω differential), forming the cornerstone of Conception de PCB à grande vitesse.

  2. Back Drilling: This critical process removes the unused copper stub from high-speed signal vias (par ex., 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 (Ne sait pas) 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) Cuivre: 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 (par ex., high-current power zones vs. high-speed signal zones) to meet specific circuit requirements.
