There is a test failure for a PCA board. The failure must be analyzed and the cause logged as a defect. The appropriate disposition for the defect must then be determined and logged.
The material ACME_PCB_3451
is a PCA board.
The operation PCB_TEST_ANALYZE_REPAIR
is being performed at resource PCB_STATION.
A PCA board with SFC number ACME-3451-000004
is to be processed at this operation.
In NC Client Maintenance
, you have retrieved your NC client (for example, LOG_NC
) and selected the Can Log Primary NC Code
and Log Secondary NC Code
checkboxes
to ensure logging of all three types of NC codes.
Proceed as follows to log a test failure:
In default Operation
POD, choose the operation PCB_TEST_ANALYZE_REPAIR
and resource PCB_STATION
.
Enter SFC number ACME-3451-000004
in the SFC
field and start it.
The external event: test fails at the bottom left test point with failure code F1-22
.
Select the FAIL
NC code in the NC Selection
plug-in.
Enter Test P358 failed with failure code F1-22
in the Comments
field in the NC Data Entry
plug-in.
Enter the Ref Des value from the test point, in the Ref Des
field in the NC Data Entry
plug-in.
Enter the failure ID and choose Add
button in the NC Data Entry
plug-in to log the FAIL
NC code.
Proceed as follows to analyze and log a defect:
Choose the NC Tree
button in the POD.
In the NC Data Tree
, select the NC code you logged and choose the Return to POD
button. Secondary NC code groups and codes are displayed in NC Selection
.
External event: examination and test of component finds that the component has a bent lead that is not making contact.
Choose the COMPONENT
NC group and the LEAD-BENT

test, analysis and repair example:
Recommendation
We recommend adding a Comment
field to the data type for the DONE
NC code to enable the user to comment on the specifics of the repair or the condition of the component.
