SMT AOI/SPI/X-ray

Product Overview

The Inline Koh Young Zenith Lite is a 3D Automated Optical Inspection (AOI) system designed for inline integration within SMT production lines.

It provides reliable defect detection while maintaining smooth PCB transfer, making it suitable for factories that require inline quality control without sacrificing line stability.

Zenith Lite is especially effective where inspection reliability and production efficiency must be carefully balanced.

When Inline 3D AOI Is the Right Choice

Inline AOI delivers the best results when:

• SMT production is continuous and well-balanced

• Product mix is stable with limited variation

• Immediate defect detection is required

• Automation level across the line is consistent

• PCB transfer logic is well-controlled

In these conditions, inline inspection supports quality control without introducing unnecessary line interruptions.

Key Characteristics of Zenith Lite Inline AOI

• High-accuracy 3D inspection technology

• Compact footprint suitable for inline placement

• Stable performance under continuous operation

• Designed for real-time inspection feedback

• Supports automated production environments

These characteristics make Zenith Lite a practical choice for inline SMT inspection.

Inline AOI and Line Flow Considerations

Inline AOI must be integrated carefully to avoid unintended production issues.

Potential challenges include:

• Line blocking caused by false calls

• Recovery delays during inspection stoppages

• Increased dependency between upstream and downstream processes

To mitigate these risks, proper integration should include:

• Stable SMEMA signal communication

• Consistent conveyor timing

• Clear NG board handling strategy

• Buffer or bypass planning where needed

Typical Application Scenarios

Inline Zenith Lite 3D AOI is commonly applied in:

• High-volume SMT production lines

• Consumer electronics manufacturing

• Automotive and industrial electronics lines

• Fully automated SMT environments

In these scenarios, inline inspection strengthens quality control while preserving production flow.

Inline vs Offline AOI – Understanding the Difference

Inline AOI focuses on:

• Immediate defect detection

• High throughput

• Continuous production

Offline AOI focuses on:

• Flexible inspection

• Reduced line dependency

• Easier handling of mixed production
