As autonomous driving technology evolves towards L3 and higher levels, the precision manufacturing of automotive LiDAR, the "core eye" of environmental perception, has become a critical determinant of its performance. Leveraging its advantages in high precision and stability, laser soldering technology is emerging as a core process for LiDAR sensor packaging. ULiLASER, with its proprietary technological breakthroughs, provides reliable manufacturing support for this advancement in autonomous driving.
Automotive LiDAR systems contain numerous precision electronic components with tiny and densely packed solder joints. Traditional soldering processes are prone to issues such as cold joints and solder splashing, which directly impact the LiDAR's ranging accuracy and stability. ULiLASER's laser soldering solution is centered around a "closed-loop soldering system," which establishes a dynamic feedback and adjustment mechanism by monitoring soldering temperature, laser power, and solder joint morphology in real-time. Combined with a soldering precision of ±0.01mm, it perfectly meets the processing requirements for micro-solder joints on both the transmitting and receiving ends of the LiDAR, preventing solder splashing at the source and increasing the soldering yield rate to over 99.9%.

In temperature control technology, ULiLASER's linear temperature control system demonstrates unique advantages. The PCB boards and optical components within automotive LiDAR are extremely sensitive to temperature, and conventional pulse-based temperature control methods can easily cause localized overheating. This system allows for temperature adjustments in 1°C increments, ensuring the heat-affected zone (HAZ) during the soldering process is controlled within a 0.1mm range, thereby preventing component performance degradation and laying a solid foundation for the long-term stable operation of the LiDAR.
The deep synergy between software and hardware is another key highlight of ULiLASER. Its proprietary laser soldering software supports intelligent multi-parameter adaptation, automatically calling upon the optimal process parameter library based on the soldering requirements of different LiDAR modules, such as the transmitter module and the scanning motor assembly. Meanwhile, the specialized soldering modules developed by ULiLASER enable various soldering forms, including spot soldering, drag soldering, and ring soldering, meeting the full-spectrum processing needs of LiDAR systems—from core chips to external interfaces—and significantly enhancing the flexibility of the production line.

As a technological pioneer in the field of laser soldering, ULiLASER has become the preferred partner for automotive LiDAR manufacturers with its product characteristics of "high precision, high reliability, and high adaptability." In the current era of rapid iteration in autonomous driving technology, the advancement of laser soldering processes not only drives a leap in LiDAR performance but also accelerates the commercialization of high-level autonomous driving. In the future, ULiLASER will continue to deepen its expertise in laser soldering technology, injecting more momentum into the intelligent transformation of the automotive industry.
