ULiLASER presents real-world AA + Laser Soldering + 3D Inspection results at EAC 2025 — LiDAR yield climbs to 97.5%, HUD throughput up 40%, headlight savings of ¥6M per year.
EAC 2025 — the Easycar Automotive Industry Conference & Expo — brought 10 000+ automotive professionals together to map the future of smart driving. ULiLASER was there with a message that resonated across booth discussions: Active Alignment, precision laser soldering and 3D visual inspection are not separate steps — they are one system.
About ULiLASER
Founded in 2016 and based in Shanghai, ULiLASER focuses exclusively on fully automatic laser soldering, with five proprietary control-software suites, a growing portfolio of utility patents, and hundreds of automotive production lines delivered worldwide.
Active Alignment — the core of camera, LiDAR, HUD and headlight manufacturing
AA (Active Alignment) technology dynamically calibrates lens-to-sensor parallelism and optical-axis intersection to achieve the clearest, most uniform image — critical as automotive cameras move past 8 MP.
For LiDAR, AA holds laser-emitter-to-receiver optical-path error to ±0.01 mm, underpinning the precision required for L3+ autonomous driving. For HUD systems, three-dimensional calibration of projection lens, mirror and display module eliminates ghost images and beam drift. On automotive headlights, AA ensures accurate optical-component alignment for consistent, safe beam projection.
Laser soldering — non-contact precision where heat is the enemy
ULiLASER’s laser soldering platform runs closed-loop constant-temperature control with responsive PID algorithms, feeding solder models in real time to hit the ideal weld profile. Its non-contact nature is what makes it safe for fragile optics in LiDAR and HUD, while still delivering high-strength joints for LiDAR transceiver chips and HUD electronic modules.
3D visual inspection — catching what 2D misses
A real 3D visual-inspection module covers every surface of automotive cameras, LiDAR, HUD and headlights. It finds subtle defects 2D inspection simply cannot — improving accuracy, cutting rejects and feeding data back into traceable quality records.
Real results, real customers
Three case studies ULiLASER shared at EAC:
- A LiDAR maker pushed first-pass yield from 88% to 97.5% with a complete AA + Laser + 3D AOI line
- A HUD producer lifted throughput by 40% and cut aftersales failures by 70%
- A headlight manufacturer climbed from 90% to 98.2% yield — saving more than ¥6 million (≈US$830 000) per year
“Smart driving’s next leap depends on manufacturing precision,” said ULiLASER’s conference representative. “The equipment line is not the place to cut corners.”
