Introduction
In the realm of micro-electromechanical systems (MEMS), such as frequency microsensors and uncooled infrared microsensor arrays, vacuum packaging is essential. This technique is crucial for shielding sensitive components from the detrimental effects of oxidation, gas flow, or thermal conductivity that atmospheric conditions may impose. Similarly, semiconductor chip packaging demands a high vacuum to ensure the accuracy and stability of devices, protecting the material from environmental corrosion.
Product Overview
To meet the stringent requirements of special products in unique environments, Han’s Laser has introduced a cutting-edge vacuum laser welding system. This system is designed to suppress plasma formation and enhance melt depth effectively. As the atmospheric pressure decreases, plasma is gradually reduced, leading to improved weld seam formation. The transition from Y-shaped to I-shaped seams occurs with decreasing environmental pressure, resulting in welds with a high depth-to-width ratio. The vacuum laser welder operates at a vacuum pressure down to 10-2Pa, featuring an integrated vision positioning system for automated weld capture.
Technological Advantages of Vacuum Laser Welding
1.Aesthetic Welds
Traditional welding in atmospheric conditions can cause rapid oxidation in high-temperature regions, absorbing gases like O₂, N₂, and H₂ from the air, which adversely affects weld quality and product performance. Welding inside a vacuum chamber or a glove box filled with inert gas isolates the material from air, yielding high-quality welds.
2.Automatic Positioning
The equipment comes equipped with a vision positioning system, enabling automatic capture and precision in welding operations.
3.Broad Welding Range
With a three-axis electric platform featuring travel ranges of 400mm (X), 300mm (Y), and 300mm (Z), the system provides an extended effective welding range, accommodating a variety of sizes and shapes.
4.Maintenance-Free Operation
The use of a fiber laser minimizes maintenance costs and power consumption with zero consumables required. The system boasts an electro-optical conversion efficiency of approximately 25%, highlighting its energy efficiency and low operational cost.
Conclusion
Han’s Laser vacuum laser welding machine marks a significant advancement in the field of precision welding. By mitigating environmental challenges and enhancing weld quality through innovative technology, this system sets a new standard for high-performance and reliability in challenging welding applications. Whether for intricate components of MEMS or robust semiconductor packaging, this technology ensures optimal results, propelling industries towards a more efficient and reliable future.
