Hints on Countermeasures against Failure
1.1 Classification of Failure Symptoms
The machine processes can be classified into Processes A, B, C, D, and E as
shown below.
Reference
Refer to "3. 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.
