Why do we miss components on a PCBA after the SMT process?

Our company outsources PCB Assembly to a factory. Sometimes, our IQC find some components are missing on the PCB. We want to know why this thing happen.
  1. The Manufacturer placed components in the wrong position.
  2. Lack of soldering during the process.
  3. Wrong reflow temperature.
  4. Choose wrong components for the PCB.
  5. Improper stencil design and thickness.
  6. Poor de-soldering and rework of components.
  7. Poor quality of PCB.
  8. Bad design of PCB.
  9. Bad materials of PCB.
