⑦ Components whose component shape is not convex.
When the above conditions are satisfied, side recognition is enabled.
(3) 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.
0.1 mm or less

6.4.3 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.
Black components cannot be recognized.
The machine can recognize the center of a component if the length of its longer side
is twice or more the length of its shorter side.
In the component drawing shown in the following table, the black/white is reversed
unlike the reality.

Setting the Vision Recognition Pattern for a BGA/FBGA
Component
6.5.1 “Vision recognition pattern settings” dialog box (BGA/FBGA)
On this dialog box, set the parameter for the recognition pattern used for a BGA or
FBGA component. When you click the <OK
> switch on the Vision data screen, the
machine displays this dialog box. See Table 6.5.1.1 for each item displayed on this
dialog box.
