The USB4 interface is becoming the standard configuration for all types of smart devices in 2025 with an irreversible momentum. From ultrabooks, flagship smartphones, and desktop workstations to in-vehicle systems, the USB4 interface—with its ultra-high transfer speed of up to 40Gbps, compatibility, and power delivery efficiency—is reshaping the connector standard. Amid this wave of technological iteration, Bubujing Technology has quietly taken a leading position in the industry.
The USB4 interface is not merely an upgrade in “speed,” but a reconstruction of “architecture” and “function.” Based on the Thunderbolt 3 protocol, it is backward compatible with USB 3.2, USB 2.0, and DisplayPort, enabling efficient integration of video, data, and power transmission through a single cable. Given such complex technological convergence, the structure and manufacturing standards of USB4 connectors have also been upgraded accordingly, placing high demands on manufacturing processes.
The development of the USB4 interface has not happened overnight. Bubujing Technology began forward-looking research and deployment of USB4 connectors as early as 2020. Through establishing its own laboratory, introducing AI-assisted simulation systems, and strengthening signal integrity testing, Bubujing has continuously conducted validation around key technologies such as 40Gbps high-speed signal transmission, high-frequency interference resistance, precision terminal crimping, and plating reliability.
Between 2021 and 2023, Bubujing’s USB4 connectors passed a series of rigorous environmental and electrical tests, including 72-hour continuous high-speed transmission tests, electromagnetic interference shielding assessments, thermal shock and plug/unplug fatigue tests. The products delivered stable results in multiple customer pilot production projects. Particularly in scenarios such as high-speed notebooks, industrial-grade mobile terminals, and intelligent cockpits, Bubujing’s USB4 connectors demonstrated superior transmission efficiency and structural reliability.
In 2024, Bubujing officially achieved large-scale mass production of USB4 connectors and now offers a full range of product solutions, including various types of USB4 female ports, male head modules, and vehicle-specific anti-shake interfaces. By introducing multiple Kyori high-speed stamping machines from Japan, FANUC and NISSEI precision injection molding machines, and 10-zone IR reflow ovens, the company ensures that every connector meets precision and performance standards in the manufacturing process.
At present, Bubujing’s USB4 connector products have obtained multiple international certifications including UL, VDE, CE, and RoHS, and meet high-standard requirements such as the IATF16949 automotive system and ISO13485 medical system. Its customer base includes well-known domestic and international motherboard manufacturers, display terminal brands, and AI smart terminal integrators, providing strong support for the full implementation of the USB4 ecosystem.
In this wave of technological revolution driven by “high-speed connectivity,” the USB4 interface is undoubtedly set to become a core standard for smart hardware over the next five years. Are you ready for a full-scale market upgrade? Choosing Bubujing’s USB4 connectors—with five years of R&D and stable mass production capabilities—is undoubtedly a wise choice for embracing the new connection era of 2025.
