Main Features of SAKI 3Di-LD2 3D AOI System
1. True 3D Inspection Accuracy
The SAKI 3Di-LD2 captures true 3D images of every solder joint and component using a high-speed projection and multiple camera system.
It detects height variations, solder bridging, missing components, and coplanarity issues with micrometer-level precision.
2. High-Speed Inspection Performance
Equipped with SAKI’s proprietary parallel processing technology, the 3Di-LD2 offers inspection speeds up to 70 cm²/sec without compromising accuracy.
This makes it suitable for fast-paced SMT lines requiring both precision and productivity.
3. Advanced 3D Image Processing
The system’s high-resolution 3D imaging engine reconstructs each solder joint in full height and shape, allowing accurate measurement of volume, area, and height—key parameters for reliable quality assurance.
4. Easy Operation and Programming
The SAKI software interface provides intuitive program creation and flexible inspection templates. Operators can set up inspection conditions quickly using CAD data or Gerber imports, minimizing setup time.
5. Inline System Integration
The 3Di-LD2 easily integrates into any SMT production line and supports full communication with placement, reflow, and MES systems. It can automatically feedback inspection data for closed-loop process optimization.
6. Compact and Rigid Design
Despite its compact footprint, the 3Di-LD2 delivers industrial-grade stability and mechanical rigidity. It maintains long-term calibration accuracy, even in high-volume environments.
