Table 67
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)
