Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Optical System Misalignment
Cause: Thermal expansion/contraction of mechanical components, vibration from adjacent machinery, or gradual wear in positioning mechanisms leading to inaccurate PCB inspection and false defect detection.
Image Sensor Degradation
Cause: Accumulation of dust/contaminants on lenses or sensors, LED light source intensity decay over time, or sensor overheating due to inadequate cooling, resulting in reduced inspection accuracy and increased false reject rates.
Maintenance Indicators
  • Consistent false defect alarms or missed defects during routine calibration checks
  • Unusual audible vibrations, grinding noises, or irregular mechanical movements from positioning stages
Engineering Tips
  • Implement predictive maintenance using vibration analysis on motion components and scheduled thermal imaging of optical/electrical systems to detect early degradation
  • Establish controlled cleanroom environment standards (ISO 14644-1 Class 8 minimum) with positive pressure and regular HEPA filter maintenance to prevent optical contamination
