Explanation
Lead Group E 1
Activates the setting of Lead
Group 1E (1).
Common
Ruler Offset E
Lead Number: 1E
Sets the number of rows in
the vertical direction.
Reflect LL.: 1E (mm)
Lead Width: 1E (mm)
Sets the diameter of the
balls.
Lead Pitch: 1E (mm)
Sets the ball pitch in the
vertical direction.
Find Pos X: 1E (mm)
Sets the reference position X
of the ball in the vertical
direction.

Group
1
Find Pos Y: 1E (mm)
Sets the reference position Y
of the ball in the vertical
direction.

Note:
The parameters other than those shown in Table 67 are not used, and should be set to 0.
(1) Special 1: Polarity judgment function
This function is used in the Simple BGA Recognition mode to judge polarity
based on whether the specified ball exists or not.
Option 1: Column number of the ball for polarity judgment in the horizontal direction.
Option 2: Row number of the ball for polarity judgment in the vertical direction.
Option 3: Polarity Ball: (0:None, 1:Exist)
(2) Special 2: The Standard BGA Recognition mode runs in this mode.
Option 1: Lower 8 bits of the index number for the ball position information
Option 4: Upper 8 bits of the index number for the ball position information
Option 2: Binarization correction parameter
Option 3: Recognition flag
(3) Special 3: Simple recognition of ceramic BGAs
This is used for recognition of the BGAs whose base is made of white ceramic.
The ball position definition information is not used.
Option 2: Ball Exist Threshold Level
The following is the actual example of the recognition.
Bit position
Excessive Ball check: (0: None, 1:Exist)

(4) Special 4: Recognition of ceramic BGAs (Using the ball position information)
This is used for recognition of the BGAs whose base is made of white ceramic.
The ball position definition information is used.
Option 1: Lower 8 bits of the index number for the ball position information
Option 4: Upper 8 bits of the index number for the ball position information
Option 2: Threshold value for judging whether the balls exist or not
