(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
The following is the actual example of recognition.
