Large-scale AI training and inference require high-speed data exchange between servers and compute nodes, placing greater demands on network bandwidth and data transmission efficiency. As a key component of data center networks, switches handle data forwarding  and high-speed interconnection between compute nodes and network devices. High-speed Ethernet connections such as 400G and 800G are already used in some AI and high-performance data center networks, while data center networks continue to evolve toward higher bandwidth.   As switch port speeds, channel counts, and data throughput increase, PCB manufacturing faces more stringent requirements for low-loss material performance, circuit fabrication precision, impedance control, and multilayer interconnection.   PCBs provide electrical connections and signal transmission paths for switch chips, high-speed interfaces, power circuits, and other functional modules. In high-speed data center switches, PCBs need to support no...

        As data centers, cloud computing, and AI infrastructure continue to demand greater  network bandwidth and data transmission capacity, 800G high-speed connectivity has been adopted in some high-performance data center switches, routers, and other high-speed networking equipment. Higher data rates impose stricter requirements on PCB materials, circuit fabrication, impedance control, and interlayer interconnections.   PCBs provide electrical connections and signal transmission paths for switch chips, high-speed interfaces, power circuits, and other functional modules. In 800G network equipment, PCB materials, stack-up construction, and manufacturing precision also need to meet product requirements related to high-speed signal integrity and power integrity.   Different 800G network devices vary in port configuration, board architecture, interface type, and inter nal interconnection, so PCB materials, stack-up structures, and circuit configurations ...
