5.1 Classification of Failure Symptoms and Helpful

Hints on Countermeasures against Failure

5.1.1 Classification of Failure Symptoms

The turret movement can be classified into Processes A, B, C, D, and

E as shown below.

Refer to "1. Outline of Actions" in "Section 2" of the instruction manual

(Volume 2: Operation (Supervisor)) for the outline of actions.

Process A : A component is picked up at Station #12 and transferred

to Station #3.

Process B : The component recognition function is implemented on

the component at Station #3.

Process C : The placement angle is corrected at Station #3 and the

subsequent stations and the component is placed on the

P.C.B. at Station #6.

Process D : The component is placed on the P.C.B. along with the

movement of the X/Y table.

Process E : The component-placed P.C.B. is discharged.

Fig. 4B29

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 in Processed D and E.

Failures can further be classified as shown in the table below.

Placement Error Components are turned vertically.

A recognition error occurs.

Components drop.

5.1.2 Helpful Hints on Countermeasures against Failure

• The first helpful hint on countermeasures against failure is to catch

precisely what kind of symptom is produced and how frequently the

symptom appears.

• The second helpful hint is to grasp the tendency (environment and

condition) of a failure.

Shown below are the concrete items to be checked.

(1) Check if the failure occurs on specific components.

(2) Check if the failure occurs on a specific production lot.

(3) Check if the failure occurs on a specific machine.

(4) Check if the failure occurs at a limited stage.

• The third helpful hint is to find in which process the failure occurs.

In normal cases, a failure after component placement is found in

the final inspection process. In such a case, it is required to track

the failure by checking all processes and specify the process in

which the failure has occurred.

It is very important to grasp a failure symptom precisely on these

helpful hints. Precise capture of a failure symptom makes it pos-

sible to track the factor and make a plan to take countermeasures

against the failure. If a failure symptom is grasped negligently,

ineffectual countermeasures may be taken and it may take much

time before the proper countermeasures are determined.

Especially, as for less failures (low generation rate), it is necessary

to take data accurately, examine the factors as a result, and ex-

ecute measures against such failures.
