AA WORKSHOP
AA Production Workshop
AA (Active Alignment) is the core process of automotive camera manufacturing: imaging live while micro-adjusting the lens-to-sensor position to lock in the optimal optical axis. TSIMSAFE operates AA process zones 1/2/3 and a class-1000 cleanroom, underpinning production consistency.
PROCESS
What is AA Active Alignment?
Conventional assembly passively positions the lens by mechanical dimensions; tolerances of focal length, threads, spacers and sensor placement stack up, so FOV and sharpness vary across a batch. Acceptable for consumer electronics — unacceptable for cars, where ADAS calibration and AVM stitching both depend on module-to-module consistency.
Before curing, AA keeps the module live and imaging: the system computes real-time MTF and optical-axis offset against a standard chart, and a six-degree-of-freedom stage adjusts lens position (translation, tilt, rotation, focus). When MTF and axis both pass, UV adhesive cures instantly to lock the position — followed by retest to cull outliers. Because the loop closes on measured results, mechanical tolerance is eliminated.
Modules produced with AA deliver markedly better FOV consistency, center/edge sharpness and wide-temperature optical-axis stability than passively assembled products — the foundation of our promise that production units match samples.
