Figure 77 is the shape defined by the component definition. It is defined to recognize only the
pads that are arranged in a regular pattern.
Also, the pads on each corner are doubly defined by each side.

2.10.6 Flip-chip recognition : Special 2 and 3
These recognition modes are used for chips that have the balls placed in a random pattern.
A file containing definitions for each ball position is use for recognition.
With Special 2, the contour tracing based on binarization is used for recognition.
With Special 3, recognition is performed by matching the individual balls.
