Selection and Application of Low-Loss Materials for High-Speed Optical Module PCBs

图片
        As AI large language models (LLMs), high-performance computing (HPC), cloud computing, and data center networks continue to evolve, 400G, 800G, and even 1.6T optical modules are becoming increasingly widespread. Higher data rates require higher-frequency signal transmission, placing greater demands on PCB signal integrity, impedance control, and signal loss performance.   As the primary carrier for high-speed electrical signal transmission inside optical modules, PCBs must not only achieve precise impedance control but also use low-loss materials to reduce transmission loss and maintain signal integrity. As a result, low-loss materials have become an essential part of high-speed optical module PCB manufacturing. As a professional optical module PCB manufacturer, HoYoGo specializes in the manufacture of high-reliability, high-speed PCBs. We provide customized multilayer optical module PCB manufacturing services to meet diverse customer requirements, deli...

Applications of High-Reliability PCBs in AR Smart Glasses

图片
       With rapid advances in artificial intelligence (AI), augmented reality (AR), computer vision, and wireless communication technologies, AR smart glasses are increasingly being adopted across a wide range of applications, including industrial manufacturing, healthcare, logistics and warehousing, education and training, and remote collaboration. Compared with conventional wearable devices, AR smart glasses integrate multiple functional modules — including display systems, processors, communication modules, sensors, and power management circuits — within a highly compact form factor. At the same time, they must maintain a lightweight form factor, low power consumption, and long-term operational stability, placing higher demands on system integration and overall reliability.   As the foundation of electronic systems, high-reliability PCBs provide a platform for electronic components while enabling electrical interconnection and reliable signal transmission. Th...

Applications of Glass PCBs in Communication Equipment

图片
          With the continued development of artificial intelligence (AI), cloud computing, big data, and high-speed network infrastructure, communication equipment is evolving toward higher bandwidth, greater integration, and faster data transmission rates. From data center switches and optical communication equipment to core network equipment, the growing demand for high-speed data transmission is placing  greater  demands on electronic systems in terms of system integration, signal integrity, and long-term reliability.   Driven by these trends, electronic interconnect technologies are evolving toward higher density, greater precision, and higher-speed signal transmission. At the same time, new substrate materials and advanced interconnect platforms are attracting increasing attention. Compared with conventional FR-4 substrates, glass-based substrates offer several potential advantages, including a lower coefficient of thermal expansion (CTE...
