(B) Corner recognition
Recognition conditions:
① Components whose whole shape is a regular square or rectangle
② Components whose corner angle R is 0.5 mm or less
③ Components whose linear portion length forming each side is 2 mm or
more
④ Components whose 4 corner points are at vertexes of a regular square or
rectangle
⑤ Components whose outline is not convex
⑥ Components with concave portions whose L1 is 10% or less of L2
⑦ Components whose sides are 0.3 mm or more when their insides are
imaged darkly at imaging
⑧ Components whose side roughness forming a linear portion is 0.1 mm or
less
♦ When the above recognition conditions are satisfied, corner recognition is
enabled.

(C) Center recognition
Recognition conditions
① Components whose ratio of width to length is 1:2 or more
② Components whose side portion is 0.3 mm or more (The inside of a side
may be hollow at imaging.)
When the above conditions are satisfied, center recognition is enabled.
Note: Concavity and convexity may exit on the component outline. However, they
have an effect on the center position and inclination.
In this case, adjust the placement data, etc.
4) Recognition component examples
The components to be supported by the component outline recognition function
are those whose shapes are close to a rectangle or regular square. The edges
forming an outline should be 0.3 mm or more.

reversed unlike the reality.
