An Automatic Optical Tester (AOT) is a high-precision inspection system designed for semiconductor packaging and electronics manufacturing, utilizing advanced 3D light field imaging and AI-driven defect detection to ensure product quality. It specializes in identifying critical defects in wire-bonding (e.g., ball misalignment, broken wires) and bumping processes (e.g., solder ball size deviations, planar misplacement) with sub-micron accuracy (±0.1 µm). Capable of scanning up to 20,000 units per hour, the VL Series line-scan models combine anti-occlusion capabilities and depth-aware 3D reconstruction to overcome limitations of traditional 2D AOI systems. Integrated with QA/QC platforms via USB/Ethernet interfaces, it generates actionable reports (CSV/PDF) and supports real-time adjustments in smart factories. Applications span automotive electronics, consumer devices, and advanced packaging (BGA, Flip-Chip), aligning with ISO and semiconductor industry standards for defect-free production
