Inspection and Defect Review Step by Step 5-7

During defect review, verify the defect visually. If there is a true defect, classify it accordingly

using the Defect Classification drop-down list. The data in the list comes from the Defect.ini

file in the INI folder of the software. If there is NOT a true defect, in other words, a false call is

made by the machine; press the Ignore button to have it removed from the defect list.

There is a pop-up menu for less frequently used functions. To display the menu, point the mouse

inside the dialog and press the right mouse button. The pop-up has nine items. The Skip Fixed

Parts item removes parts in the review list that have been modified. The Ignore Part item

ignores parts with multiple defects with one click. The Move Back item “undoes” the Ignore or

Next button. The Ignore item ignores a defect. Have the Auto Retest Fixed item selected will

automatically re-test parts that are modified during the review process. The Ignore Block item

ignores all defects on a selected block. The Next Slice item is for 3D inspection only. It ignores

parts within the same slice and moves on to parts in next slice. The Next 3D Site item is also for

3D inspection only. It ignores parts within the same 3D site and moves on to parts in next 3D site.

The Pause Review item pause the current review process. If the same image set was selected and

being reviewed again, the user can select to review the defect from where it was paused during

last review, instead of review from the beginning of the defect list.

You can also log the false calls. Select Vision>Recipe Option from the Main Menu. Select the

Log False Call checkbox in the Recipe Options dialog. When Log False Call is selected, the

Ignore Part button will change to a False Call button. Pressing the False Call button classifies

the defects as false calls and leaves them in the defect list. The Index specifies the classification

linked to the False Call button. For example, if the false call classification is in line 12 in the

defect.ini then the Index should be set to 12. The total number of false calls on the board is

reported in the defect report.

5-8 Inspection and Defect Review Step by Step

Recipe programmers can fine-tune the inspection recipe during defect review. An alternate

template can be added to handle new alternate component markings and the inspection pass score

can be adjusted to handle random noise in the image.

The Next button on the Review Failed Parts dialog moves to the next defect whether it is on the

same part or next part. The Next Part button moves to the first defect on the next part of the

defect list.

Inspection and Defect Review Step by Step 5-9

The following is a sample Defect.ini file:

[01] Unclassified

[02] Missing Part@S

[03] Wrong Part@S

[04] Tombstone Part

[05] BillBoard Part

[06] Skew Part

[07] Wrong Polarity

[08] Lead Solder Bridge

[09] Bend Lead

[10] Insufficient Solder

[11] Solder defects

[12] False Call

When there is a missing part defect (e.g. U1 is missing) the AXI would probably detect one

marking defect, some lead defects and many solder defects for the same reference designator

(U1). However, if U1 is missing the user probably does not care about the other defects the

system detects. To simplify defect review, the software has two main types of defects: Singular

and Multiple. One Reference ID can have only one singular defect. Missing part is a good

example of the singular defect.

In the defect.ini file the @S symbol trailing the defect description indicates that the defect is a

singular defect. Defects without @S are of type Multiple.

You can assign default classifications based on the inspection type (mark, solder and lead) to

speed up the defect classification process. The following section can be found in the YesAX.ini

file.
