In the digital age, characterized by the explosion of large AI models, the iterative upgrading of cloud computing, and the comprehensive penetration of 5G technology, data transmission rates are breaking through towards 448Gb/s-PAM4 and even higher standards. High-speed backplane connectors, as the "neural hub" of core equipment such as data centers and high-end servers, have their performance directly determining the stability and efficiency of the entire system. Traditional manufacturing processes are increasingly inadequate in meeting the development needs of connector miniaturization, high density, and low loss, while the precise empowerment of laser technology is becoming a key engine for solving industry pain points. In this wave, Fly Laser, with years of dedicated effort, has forged a leading position in the domestic laser industry, injecting strong momentum into the high-speed backplane connector industry with cutting-edge technology.
The core manufacturing pain points of high-speed backplane connectors are concentrated in the processing difficulties of key materials such as copper alloys. Copper materials have an insufficient absorption rate of less than 5% for traditional infrared lasers, easily leading to defects such as shallow melt pools, severe splashing, thermal cracks, and hydrogen pores, directly threatening connection reliability. At the same time, as connector size shrinks and pin density increases, the requirements for processing accuracy and thermal impact zone control reach micron-level standards, which traditional welding and drilling processes simply cannot meet. Laser technology, with its inherent advantages of non-contact processing, high-precision control, and low thermal impact zone, has become the optimal solution to these problems – achieving a welding yield of over 99%, stable electrical conductivity of solder joints, and precise processing of micro-holes, maximizing protection of the substrate from damage.
As a leader in the domestic laser industry, Fly Laser has been deeply involved in the field of laser applications for high-speed backplane connectors for many years, always taking technological innovation as its core driving force, accurately discerning industry development trends, and creating comprehensive laser processing solutions. Looking back at its development history, since its establishment in Dongguan in 2008, Fly Laser has been committed to laser technology innovation, starting from early research and development of basic equipment such as laser marking and welding, and gradually specializing in precision laser processing. In 2020, the company completed a brand upgrade, officially changing its name from "Dongguan Fly Laser Technology Co., Ltd." to "Guangdong Fly Laser Intelligent Equipment Co., Ltd.", marking a new stage of large-scale and intelligent development for the enterprise. Over the past decade, Fly Laser has not only built a modern production base spanning nearly 10,000 square meters but has also established a global marketing and service network covering core regions in East China, Central China, North China, and Southwest China, as well as more than 30 countries and regions including Brazil, India, and Thailand, achieving a leap from a regional enterprise to a global laser equipment service provider. In the high-speed backplane connector laser application field, Fly Laser, with its keen insight into industry needs, continuously iterates its technology. Addressing the core pain points of copper processing, it has developed a dedicated laser processing system, achieving a breakthrough upgrade in key technologies: using a customized wavelength laser source, significantly increasing the absorption rate of copper, effectively reducing reflection risks, minimizing spatter and porosity defects, and significantly enhancing welding penetration stability; coupled with its independently developed high-precision visual positioning system, it achieves closed-loop management of the entire process, including automatic capture and correction before welding, precise control during welding, and real-time detection after welding, ensuring impeccable processing accuracy for every weld point and every micro-hole.
In core processes such as laser drilling and laser welding of high-speed backplane connectors, Fly Laser's technological advantages are evident. Its laser drilling equipment can precisely process micro-holes with a diameter as small as 50 microns, meeting the stringent requirements of high-end HDI boards for micro-holes and narrow spacing, with a heat-affected zone of less than 0.5 millimeters, completely solving problems such as rough hole walls, residual adhesive, and copper peeling that occur in traditional processing, enabling miniaturization and high-density design of connectors; the laser welding system, with its energy output stability within ±1%, achieves efficient and reliable connection of copper, aluminum, and dissimilar metals, with welding joint strength far exceeding traditional processes and significantly reduced contact resistance, perfectly matching the extreme requirements of high-speed transmission for signal integrity. More importantly, Fly Laser's solutions can be easily integrated into automated production lines, enabling flexible production of multiple varieties and high volumes, significantly reducing manual intervention and consumable consumption, providing strong support for enterprises to improve production efficiency and save costs.
