When the end position of the first ball is (-6.0 mm, -5.0 mm) in the example in “First
element arrangement.”
Offset X : - 6.0
Offset Y : - 5.0
Offset Z : 0 (not used)
Offset Theta: 0
- Normally, enter “0” to each field of the setting item “Tolerance.”
• Next, set the element group arrangement.
To set the arrangement, the setting items “Dimension”(Point, 1D, 2D), and “Count” and
“Pitch” of the “Column” and “Row” are provided.
④
Dimension (Point, 1D, 2D),
For a ball/land element, the dimension is two. Select “2D.”
Note: For arrangement of only one column and one row, specify “2D” also.
◆ The figure shows the pitch of each element group.
- In the example, the number of lead columns located in the first element group is nine.
Enter “9” to the “Count” field displayed under the setting item “Column.”
Note: For arrangement of only one line, enter “1.”
- When the pitch is 1.5 mm, enter “1.5” to the “Pitch” of the “Column” field.
Note: For arrangement of only one line, enter “1.5” also.
- Normally, enter “0” to the “Tolerance” field.
- Since the number of lead rows located in the first element group is six, enter “6” to the
“Count” field of the “Row” setting item.
Note: For arrangement of only one row, enter “1” to the “Count” field.
- When the pitch is 1.27 mm, enter “1.27” to the “Pitch” field of the “Row” setting item.
Note: For an arrangement of one row only, enter “1.27” to the “Pitch” field too.
- Normally, set “0” to the “Tolerance” field.

Missing Elements
In the example, there is missing balls (lands) on the first element group. If there is/are a
missing ball(s)/land(s), specify this setting item also in the same manner as that of a
BGA/FBGA.
Up to four blocks of missing balls/lands can be specified per element group.
To specify a block, set the first missing ball/land position of the column and row respectively
and the number of lines having missing balls/lands located continuously in the same manner
when you set those of a BGA/FBGA component.
- If there is no ball/land on three columns from the second column and no balls/lands on
two rows from the fourth row, enter values as shown below:
“Start” of the “Column” field : 2
“Count” of the “Column” field : 3
“Start” of the “Row” field : 4
“Count” of the “Row” field : 2
Note: If there is no ball/land at five or more portions, divide the element group further, then
define those divided element groups.
●
Here, you have finished setting an element group.
● Next, define a recognition element of this element group.
Only one element can be defined per element group.
Even though you define two or more elements, they are handled as “invalid”.
Click the <Add> button in the “Element” setting field.

3. Operation on the “Element” screen
①
Type
You can specify a ball or land as an element type of ball components.
This version does not support a column.
When you specify a land as an element, you can select a circular land or rectangular land.
For a bump, specify “Ball” as an element type from the “Type” combo box.
For an electrode that is flat entirely, specify “Land.”
- In the example, a ball is used. Select “Ball” from the “Type” combo box.
②
Reference pos. (position)
The reference position of a ball/land element is the center of an element.
- Select “Center of an element” from the “Reference pos.” combo box.
③
Polarity
This item specifies the brightness of the shot image of an element.
- Normally, the light that illuminates a ball/land element brightly is used for ball
components. Select “Bright” from the “Polarity” combo box.
Note: Since a CBGA illuminates the surroundings of a ball, select “Dark.”
④
Offset
Normally, this setting item is not used. Enter “0” to each field of this item.
⑤
Element size
Enter the size of an element.
Since the shape of a rectangular land is still a square, enter the same value to both the
“Width” and “Length” fields.
- In the example, the diameter is assumed to be 0.5 mm.
Enter the following values.
Width: 0.5
Length: 0.5
- Normally, the “Tolerance” setting item is not used.
Do not change this field setting “0”.
⑥
Ball/Land
For a land, you can select a circular land or rectangular land.
Touch the corresponding check box.
- In the example, a ball element is used, so these check boxes do not appear on the
screen.
⑦
Inspection
To u c h the check box of the item to be inspected.
The check items “Diameter” and “Area” are the same as those for a BGA/FBGA. Specify
the corresponding check level in %. The default value for each check level is 50 %.
Specify the check level of the “Ball exist?” check in %. also However, the percentage
indicates the internal evaluated characteristics. Normally use the default value, “30 %.”
For a land element, this item is handled as “invalid” even though you specify this item, and
the machine does not perform the check to see if a ball exists on a component.
- Normally, the setting item “Average diameter” is not used.
- If you perform the “Diameter,” “Area” and “Ball exist?” checks with specifying the default
value respectively, the following values are used for each check:
Inspection √ Area : 50 % (default)
√ Diameter : 50 % (default)
√ Ball exist : 30 % (default)
Average diameter:
You have to click each check box only.
• Here, you have finished entering data on an element. When you click the <OK> button
at the lower right corner, the “Element Group” screen reappears.
You have finished defining the first element group. When you click the <OK> button at
