In today's era of thriving autonomous driving technology, vehicles are transforming from mere means of transportation into highly intelligent mobile terminals. The core support for this transformation is the complex and sophisticated intelligent driving system. Among these, visual algorithms, serving as the "intelligent brain" of autonomous driving, undertake critical tasks such as identifying road signs, monitoring vehicles and pedestrians, and perceiving the surrounding environment. Their performance directly determines the safety and reliability of autonomous driving.
Visual algorithms are highly dependent on precise image data input, and in-vehicle cameras are the primary source for this data acquisition, serving as the "eyes" of autonomous driving vehicles. It is no exaggeration to say that the quality of in-vehicle camera performance, whether it provides the visual algorithm with a clear and sharp "eagle eye" or a blurred and chaotic "dim eye", will make a world of difference to the visual algorithm's final decision. High-quality in-vehicle cameras can capture rich and clear image details, providing an accurate and error-free data foundation for the visual algorithm, enabling it to precisely identify various complex road conditions and traffic participants, and make correct driving decisions in a timely manner. Conversely, low-performance cameras may lead to blurred images and missing information, misleading the visual algorithm and causing serious safety hazards.
Given the critical position of in-vehicle cameras in the autonomous driving system, every single process in their manufacturing is of utmost importance. AA (Active Alignment) technology and laser soldering technology play an indispensable role in this process. AA technology in in-vehicle camera production is akin to a precision craftsman with a "microscopic perspective". Under traditional processes, the alignment of lenses and image sensors often relies on manual experience, making deviations difficult to avoid, resulting in inconsistent imaging quality and persistently high defect rates. AA technology, by means of advanced image analysis systems and precision motion control devices, performs micrometer-level precise calibration of optical components. During the assembly process, it monitors key metrics such as image clarity and distortion in real-time, and upon detecting any slight deviation, quickly adjusts the positions of the lens and sensor to ensure they are in the optimal collaborative state. In-vehicle cameras processed using AA technology show significantly improved imaging quality, with a substantial reduction in defect rates caused by optical alignment issues, laying a solid foundation for the product's high-performance output.
Laser soldering technology also demonstrates exceptional advantages in in-vehicle camera manufacturing. The soldering process, serving as the link connecting various key internal components of the camera, has its quality directly related to the product's stability and service life. Traditional soldering processes, such as soldering iron welding and wave soldering, suffer from drawbacks like a large heat-affected zone and poor solder joint consistency, easily leading to issues like cold solder joints and short circuits, which reduce product reliability and lower the yield rate. In contrast, laser soldering technology, leveraging a high-energy-density laser beam, can instantly melt the solder, achieving precise soldering. In the soldering of internal circuit boards and sensors within cameras, the heat-affected zone can be precisely controlled to a minimal range, effectively avoiding thermal damage to surrounding precision components. Concurrently, its automated operation and precise parameter settings ensure high consistency in the size and shape of each solder joint, significantly enhancing solder joint strength. Following the application of laser soldering technology, the rework rate for in-vehicle cameras caused by poor soldering has significantly decreased, greatly enhancing the overall reliability of the products.
