3D Application | Mobile Phone Middle Frame Inspection


Customer Requirements:

Inspect the appearance and dimensions of middle frames, back covers, and center plates, including ultra-narrow bezels (~0.2 mm). Traditional structured light systems lack the resolution, while line laser solutions are slow and less accurate—failing to meet high-throughput and high-precision needs simultaneously.


Megaphase Solution:

· Equipped with the high-resolution Sizector® S162170 3D camera (16.2MP), capable of capturing 7–8 pixels even on 0.2 mm bezels;
· <1 second point cloud acquisition per frame, ideal for inline full inspection;
· Supports multiple inspections: flatness, height difference, foreign object, and assembly;
· No scanning or motion mechanism required, eliminating motion errors and improving system stability.


Project Results:

· Successfully deployed on multiple mass production lines, enabling fast and precise middle frame inspection.
