AA, Laser Soldering, and 3D Vision Inspection: The Optimal Combination for Enhancing Automotive Camera Production Capacity and Yield

With the accelerating popularization of intelligent driving technology, the market demand for automotive cameras, which serve as the "eyes" sensing the external environment, is experiencing explosive growth. However, traditional production processes are increasingly struggling to meet the requirements of high-precision, high-volume production. Breaking through the dual bottlenecks of capacity and yield has become a critical issue that automotive camera manufacturers urgently need to address. Leveraging years of deep industry experience, ULiLASER has innovatively integrated AA (Active Alignment) technology, Laser Soldering technology, and 3D Vision Inspection technology to create an optimal solution package for automotive camera production. This has successfully assisted numerous companies in achieving a leapfrog improvement in both production efficiency and product quality.

Three Core Technologies, Building a Closed-Loop Production Advantage

AA technology is a core process in automotive camera production, achieving precise alignment between the lens and image sensor through active adjustment, ensuring imaging quality. However, this is merely the first step towards high-quality production; the subsequent soldering and inspection stages are equally crucial.


ULiLASER's Laser Soldering technology serves as a powerful tool to guarantee soldering quality and efficiency. Unlike traditional soldering methods, laser soldering utilizes a high-energy-density laser beam to instantly melt solder, offering significant advantages such as rapid heating speed and a minimal heat-affected zone (HAZ). This characteristic is critically important for automotive cameras which integrate delicate optical and electronic components internally, effectively preventing damage to sensitive parts caused by heat diffusion during soldering and ensuring stable product performance. With its independently developed precise laser energy control system, ULiLASER's equipment can maintain laser energy output error within a very small range for solder joints of different specifications, ensuring uniform and robust solder joints, and significantly reducing the probability of defects such as voids or cold joints.


Furthermore, 3D Vision Inspection technology equips quality control with penetrating insight. ULiLASER's 3D Vision Inspection system employs advanced structured light imaging and deep learning algorithms to perform comprehensive, high-precision inspection of the automotive camera's appearance, internal structure, and soldering quality. Whether it's a subtle solder height deviation or internal assembly defects difficult to detect with the naked eye, they can be quickly and accurately identified. The inspection precision reaches 0.01mm level, and the inspection speed achieves processing multiple products per second, enabling 100% full inspection during the production process and ensuring that every shipped automotive camera meets stringent quality standards.


AA technology ensures precise alignment, laser soldering achieves reliable connection, and 3D vision inspection guarantees quality. These three technologies are interconnected, forming a complete production closed loop from assembly to soldering to inspection, providing robust assurance for high-quality, high-efficiency automotive camera production.

Extensive Practical Experience, Serving Numerous Industry Leaders

ULiLASER's technical strength in the field of automotive camera production has been rigorously tested and refined through numerous practical projects. Over the years, ULiLASER has established deep cooperative relationships with many leading domestic automotive camera manufacturers, providing them with customized production solutions.

When serving a well-known automotive electronics supplier, the company's existing production process suffered from low capacity and unstable yield rates. The ULiLASER team conducted in-depth research into their production process and identified heat damage from traditional soldering and oversights in manual inspection as the main issues. Based on this, we deployed the complete AA + Laser Soldering + 3D Vision Inspection solution. Following the project's implementation, the client's automotive camera production line achieved a 200% increase in capacity, and the yield rate surged from the original 88% to 99.5%, significantly enhancing the company's market competitiveness.

Another company, specializing in the R&D and manufacturing of high-end automotive cameras, faced challenges with welding and inspection of complex camera structures during new product mass production. Leveraging extensive technical experience, ULiLASER specifically optimized the laser soldering path planning and 3D vision inspection algorithms, successfully overcoming technical hurdles and helping the company smoothly achieve large-scale production of new products. The product quality received high recognition from terminal automotive manufacturers (OEMs).

Similar successful cases are abundant throughout ULiLASER's development history. The successful delivery of each project is inseparable from ULiLASER's strong technical R&D team, comprehensive after-sales service system, and deep understanding of industry demands. From solution design, equipment production to installation and commissioning, and personnel training, ULiLASER provides professional, efficient services throughout the entire process, ensuring the rapid and stable operation of the client's production system.
