Refer to "4. Surface Mounting Mechanism" in "Chapter 1 (Vol. 1: Guide)" for
the outline of actions.
Process A : The placement head moves to the feeder base and picks up a
component.
Process B : The head moves to the area where the component recognition
camera is installed and a component recognition process is
taken there.
Process C : The placement angle is corrected while the head is moving to
the PCB positioning section.
Process D : The component is placed on the PCB.
Process E : The component-placed PCB is discharged.

Based on these processes, failures can be divided roughly into the following two
types.
Failure before Component Placement : This type of failure occurs mainly in
Processes A, B, and C.
Failure after Component Placement : This type of failure occurs mainly at
Processes D and E.
