I. Root Causes of Component Misplacement

1. Human Error
   • Manual placement inconsistencies in printed circuit board assembly processes
   • Operator fatigue during high-volume PCB prototyping runs
2. Process Variability
   • Inconsistent solder paste deposition affecting multilayer PCB design
   • Thermal expansion causing component shifts during reflow soldering
3. Equipment Limitations
   • Legacy pick-and-place machines struggling with 01005 component placement
   • Inadequate AOI coverage for complex high-density interconnect (HDI) PCB structures
