Leveraging deep expertise in de alta velocidad, con cuenta de alta capa fabricación de PCB, UGPCB has developed this flagship 26-layer server PCB for next-generation High-Performance Computing (HPC), Servidores AI, and cloud data centers. It is engineered to deliver exceptional electrical performance and reliable physical structure to support extreme computational loads.
Product Definition & Descripción general: What is a High-End Server PCB?
A high-end server PCB is a complex, multi-layer circuit board designed to host core components like CPUs, memoria, high-speed interfaces (p.ej., Pítico, CXL), and power management units, and to establish ultra-high-speed, highly reliable electrical connections between them. It is not just a mechanical substrate but a critical platform for ensuring signal integrity and power integrity at GHz frequencies. Este UGPCB product features a sophisticated 26-layer PCB stack-up, utilizing advanced materials and processes specifically engineered for demanding applications like big data processing and AI training.
Core Design Points & Principio de trabajo
The primary function of a server PCB is to provide a low-loss, low-interference transmission path for high-speed digital signals and high-current power delivery. Its design revolves around several key principles:
-
Integridad de señal (Y): The use of materiales de alta velocidad (tg 170) and precise control over trace width/spacing of 0.08mm/0.09mm minimizes signal attenuation and distortion, ensuring error-free data transmission at rates of tens of Gb/s.
-
Integridad de poder (PI): The incorporation of 2oz heavy copper (2/2 onz) for power and internal planes reduces DC resistance and temperature rise, delivering ample and clean power to high-power chips like CPUs/GPUs.
-
Control de impedancia & Fondos de fondo: Strict impedance control is applied to high-speed channels. A key innovation is the use of backdrilling technology to remove the unused conductive stub (barrel) of plated through-holes, eliminating signal reflection points—a core process for enhancing signal quality in PCB de alta velocidad.
-
Gestión Térmica & Fiabilidad: A finished board thickness of 2.97mm ±10% y high Tg 170 material provide excellent mechanical strength and heat resistance, ensuring the PCB remains stable and reliable under the prolonged, high-temperature, full-load operation of servers.
