Integrating 10.6 µm CO₂ Laser Marking and Stealth Dicing in a Single Device
Abstract:
The integration of 10.6 µm CO₂ laser marking and stealth dicing technologies within a single device offers a streamlined solution for precision glass processing. This paper explores the feasibility of combining these two technologies and discusses the design considerations necessary to achieve optimal performance.
Introduction:
Laser marking and stealth dicing are critical processes in the glass industry, particularly for applications such as smartphone displays, automotive windows, and solar panels. The 10.6 µm CO₂ laser is renowned for its precision and control in glass processing. Stealth dicing, a method of cutting glass using laser-induced stress, offers a clean and precise cutting solution without visible damage to the surface. Integrating these technologies into a single laser marking machine (LMM) can enhance efficiency and reduce production costs.
Materials and Methods:
To assess the feasibility of integrating 10.6 µm CO₂ laser marking and stealth dicing, we evaluated the hardware requirements, software control systems, and process parameters. The hardware must support both marking and dicing capabilities, including a high-precision galvanometer scanner for directing the laser beam and a stable laser source with adjustable power output. The software must be capable of controlling both processes, allowing for precise synchronization and coordination.
Results:
Our findings indicate that with the appropriate hardware and software, it is possible to integrate 10.6 µm CO₂ laser marking and stealth dicing into a single LMM. The key to successful integration lies in the precise control of the laser's power, speed, and path. By adjusting these parameters, we can achieve both high-quality markings and precise cuts without visible damage to the glass surface.
Discussion:
The integration of these technologies offers several advantages. Firstly, it reduces the need for multiple machines, saving floor space and reducing capital expenditure. Secondly, it streamlines the production process, as a single LMM can perform both marking and cutting, reducing the need for additional handling and potential damage to the glass. Lastly, it allows for greater flexibility in design, as complex patterns can be marked and cut in a single operation.
Conclusion:
The integration of 10.6 µm CO₂ laser marking and stealth dicing into a single LMM is not only feasible but also offers significant benefits in terms of efficiency and precision. By carefully designing the hardware and software components, we can create a system that meets the demanding requirements of the glass processing industry.
