In the era of explosive growth in computing power, connector manufacturing is ushering in a "precision revolution".
AI large-scale model training clusters are continuously expanding from thousands of GPUs to hundreds of thousands and even millions of GPUs. Each generational leap in computing infrastructure places near-stringent demands on the performance and production capacity of high-speed connectors. With 224G and even 448G-PAM4 transmission rates becoming industry standards, high-speed backplane connectors, DAC high-speed copper cable assemblies, and server internal interconnect systems are no longer simply combinations of "wires" and "terminals"—they bear the massive data throughput between GPU clusters. Any tiny fluctuation in solder joint impedance or structural deviation can be amplified into a system-level failure in the signal link.
For leading computing server connector manufacturers, choosing a laser equipment supplier has long transcended the scope of equipment procurement; it is a strategic decision concerning process capability, mass production stability, and supply chain security. Fly Laser is precisely the preferred partner repeatedly validated by leading companies in this field.
Why are leading manufacturers elevating the selection of laser equipment suppliers to a strategic level？
In the field of AI server manufacturing, the precision machining of connectors and cable assemblies directly determines the signal integrity and long-term reliability of the entire system. The current challenges facing the industry are concentrated in three dimensions：
High-rebound dilemma in materials
Copper alloys and gold-plated copper terminals have an absorption rate of less than 5% for traditional infrared lasers, making them highly susceptible to spatter, unstable weld penetration, and thermal cracking, directly threatening the quality of high-speed signal transmission. Leading industry solutions have introduced 515nm green and blue short-wavelength light sources, increasing the absorption rate of copper to over 40%, thus physically solving the problems of "cold welding" and "incomplete welding" with highly reflective materials.
Structural end limit protection
The metal insert is close to the plastic matrix with a wall thickness of only 1mm. The heat of traditional welding can easily cause burns and deformation of the plastic. The leading laser process compresses the heat action time to milliseconds through ultra-high-speed scanning and precise energy control, achieving zero-defect welding that "only melts metal and does not damage plastic"
Flexible manufacturing on the production capacity side
AI connectors are characterized by small batches, diverse varieties, and rapid iteration, making production line changeover efficiency a core competitive advantage. Solutions equipped with vision-guided fully automated cutting and welding technology can achieve one-click switching of process formulas without changing fixture hardware, truly realizing on-demand production with zero changeover costs.
Fly Laser: A "Process Partner" Deeply Rooted in High-Speed Interconnect Precision Manufacturing
Since its establishment in Dongguan in 2008, Feilai Laser has always been committed to innovation in laser technology. Starting with basic equipment R&D, it has gradually deepened its expertise in precision laser processing. It has now built a modern production base of nearly 10,000 square meters and established a marketing and service network covering core regions in China and more than 30 countries and regions worldwide. In the high-speed backplane connector and AI server interconnect component manufacturing sector, Feilai Laser, with its precise understanding of industry needs, has forged a path from "equipment supplier" to "full lifecycle process partner."
Technological In-Depth Analysis: Overcoming the Dual Challenges of Highly Reflective Materials and Extremely Narrow Spacing
Addressing the high reflectivity of copper alloys and gold-plated terminals, Fly Laser's iteratively developed dedicated laser processing system employs a customized wavelength laser source, significantly enhancing the copper's absorption rate and effectively reducing spatter and porosity defects, resulting in a markedly improved weld penetration stability. Coupled with its independently developed high-precision visual positioning closed-loop system, it achieves full-process management from pre-weld automatic capture and correction to precise control during welding and real-time post-weld inspection, ensuring impeccable processing precision for every weld point and every micro-hole.
In the field of precision welding for DAC high-speed copper cable assemblies, Fly Laser's process capabilities cover the interconnection needs of 30-34AWG ultra-fine wire diameters and high-density connectors. Through precise laser energy control, it achieves a significant improvement in welding CPK value and pull-out force. Its ultraviolet laser cutting system utilizes the 355nm "photon direct molecular bond breaking" cold processing principle, achieving a cutting accuracy of ±0.005mm. In structures with conductor spacing of only 0.2-0.5mm, it precisely cuts the target without damaging adjacent insulation layers.
Mass production validation: A "vote of confidence" from leading customers' supply chains.
