       During semiconductor manufacturing, wafer inspection, metrology, and electrical testing equipment are used to evaluate wafer defects, critical process parameters, and the electrical performance of semiconductor devices, respectively. Different types of equipment vary in testing targets, signal types, and operating methods, placing different demands on signal transmission, electrical connections, and long-term operational stability. As important components of these electronic systems, PCBs provide electrical interconnections and signal transmission paths for various functional modules.   HoYoGo is a professional  wafer inspection equipment PCB  manufacturer with capabilities in high-reliability, high-precision, multilayer, and high-speed PCB manufacturing. To meet the requirements of wafer inspection equipment for signal transmission, circuit precision, complex interconnections, and long-term reliability, manufacturing these PCBs requires particu...

        AI computing, cloud data centers, and high-performance computing platforms handle large volumes of network, storage, and security-related data traffic. DPUs (Data Processing Units) can handle tasks such as network transmission, storage access, security, and infrastructure management, offloading some infrastructure processing workloads from host CPUs. As DPU network bandwidth and host interface speeds increase, high-speed interconnections on accelerator cards place greater demands on PCB signal transmission performance, manufacturing precision, and long-term reliability.   DPU accelerator cards typically integrate DPU chips, high-speed network interfaces, memory, power circuits, and other functional components, and connect to server systems through high-speed interfaces such as PCIe. Different products vary in network speeds, interface configurations, board architectures, and functional designs. PCB materials, stack-up structures, and interlayer interconn...

       AI training, inference, and large-scale data processing involve frequent read and write operations for models, datasets, and intermediate data, placing high demands on the data throughput and access efficiency of server storage systems. NVMe (Non-Volatile Memory Express) SSDs based on the PCIe interface are widely used in server and data center storage systems. In some AI servers, local NVMe SSDs are used for system storage, data caching, and temporary data read/write operations, providing high-speed local storage support for computing workloads.   AI servers can be configured with NVMe SSDs of different specifications and form factors according to system architecture and storage requirements. As PCIe data rates increase, meeting signal integrity requirements calls for tighter control of PCB material properties, circuit fabrication precision, impedance, and via structures. Different servers and NVMe storage devices vary in interfaces, board  structur...

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...
