NG Buffer: Simplifying Defect Management in SMT Production

The NG Buffer (bad product buffer) is a critical material handling system designed to intelligently manage and isolate defective PCBs in automated SMT production lines. 

Positioned after inspection stations such as AOI (automated optical inspection) or SPI, it ensures that defective boards are automatically removed from the main production process, 

preventing them from entering subsequent value-added steps.

Key Features and Functionality:

Automated Board Sorting: Integrates with the line's inspection software to automatically identify and divert boards marked "NG" or "Fail" by the inspection system.

Dedicated Isolation: Provides secure, isolated storage for defective PCBs, eliminating the risk of mixing them with good products and preventing costly rework errors.

Continuous Process Maintenance: Seamlessly remove defective boards, allowing the main production conveyor to run continuously, maximizing Overall Equipment Effectiveness (OEE).

Flexible Handling Options: Often equipped with multiple output lanes or designated trays, it allows for classification of different defect types (e.g., solder paste issues, component placement errors), simplifying analysis.

Operator Alerts: When the buffer is full and requires attention, operators are alerted via the HMI (Human Machine Interface) or an andon, streamlining workflows.

SMEMA Compatibility: Utilizing a standard interface design, it seamlessly communicates with upstream and downstream equipment on the SMT production line.

Key Benefits:

Enhanced Quality Control: Enforces strict "quality gates" to ensure only qualified products enter production.

Improved Efficiency: Eliminates the need for manual intervention during board removal, reducing labor and potential errors.

Enhanced Traceability: Creates a clear audit trail of defects, facilitating rapid troubleshooting and improving yield.

Process Optimization: Provides a physical buffer, separating the inspection process from subsequent stages, preventing line downtime.
