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.
