AOI is essential—but poorly optimized AOI can become the largest bottleneck in an SMT line.
AOI optimization is not about relaxing limits blindly.
It is about engineering judgment, data context, and flow awareness.
Over-aggressive thresholds
Poor golden board strategy
Optical artifacts
Upstream process variation
False calls:
Increase manual review
Create line blocking
Reduce operator trust
Risk-based inspection
Component-level tuning
SPI-aware parameter logic
AOI must match:
Line takt time
Recovery capability
Buffer availability
False call rate
Review time per board
AOI cycle time
→ SPI Optimization
→ Buffer Strategy
→ AOI False Call Optimization
