1. Product Overview & تعريف

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, ذاكرة, 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, سلامة السلطة, and thermal performance.

The specifications you provide (سمك المجلس: 2.8mm ±10%, 22 طبقات, 2/1 oz Copper Weight, 0.1/0.1 mm Trace/Space) define a typical high-layer-count, high-density, 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 PCB designs hinges on mastering a range of cutting-edge technologies:

Stack-up & السيطرة على المعاوقة: The complex 22-layer stack-up requires precise calculation to achieve strict التحكم في المعاوقة (typically 50Ω single-ended, 100Ω differential), forming the cornerstone of high-speed PCB design.
الحفر الظهر: This critical process removes the unused copper stub from high-speed signal vias (على سبيل المثال, for PCIe, DDR buses), significantly reducing signal reflection and attenuation, and is central to enhancing signal integrity.
High-Speed Laminate Application: We utilize premium high-speed materials like IT-968G & IT-180A from ITEQ. Their low dissipation factor (ص) and stable dielectric constant (DK) ensure signal purity and low latency. A high Glass Transition Temperature (تيراغرام >170°C) guarantees material reliability under the prolonged high-temperature operation of servers.
RTF (Reverse Treated Foil) نحاس: Its smoother surface profile effectively reduces “skin effect” losses for high-frequency signals on the conductor surface, further enhancing high-speed performance.
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 (على سبيل المثال, high-current power zones vs. high-speed signal zones) to meet specific circuit requirements.

3. أداء & الميزات الهيكلية

Exceptional Electrical Performance: Extremely low signal loss and excellent impedance consistency meet the demands of high-speed protocols like PCIe 4.0/5.0 and DDR4/DDR5.
Ultra-High Reliability: يوافق (الذهب الغمر بالنيكل غير الكهربائي) surface finish provides a flat soldering surface and superior oxidation resistance, ensuring long-term connection reliability. The 10oz thick inner copper cores (combined with the 2/1oz design) offer robust current-carrying capacity and thermal pathways for power layers.
Precision Manufacturing Capability: ال 0.1/0.1 mm trace/space and a minimum finished hole diameter of 0.25mm demonstrate UGPCB’s top-tier expertise in high-precision تصنيع ثنائي الفينيل متعدد الكلور.
Robust Thermal Management: The 2.8mm thick board structure, combined with thick copper design, provides excellent thermal dissipation, aiding overall system cooling.
