Table 5
Caution:
In Table 5, the reference lead positions are displayed as the Find Pos.
In this way, the component data can normally be created just by specifying the minimum
necessary data.
1.4 Precautions concerning the component data definitions
This section describes points to notice on component data setting.
1.4.1. ReflectLL.
Caution is required in recognizing to the lead length. When the component is read as an
image, the lead may appear different in the image from the actual image.
The bent parts of the gull-wing shaped leads look black in the image and are hard to be
recognized.
In this case, it is necessary to specify the data using the shape that is visible on the image,
rather than the actual component shape. As can be expected from the item name “ReflectLL.”
on the data definition screen, the length of the portion that is visible in the image is supposed
to be set on the screen.

1.4.2. Component sizes (chip component)
When the chip component (capacitors) and other components whose tip is rounded, the
component size on the image may be different from the actual component size.
In this case, the size on the image should be set.

2. Details of the component data setting
As already mentioned, it is possible to create the data for the standard components with the
minimum necessary data.
In the component recognition mode, the components are divided into the groups shown below
and the data is created for each mode.
<IC components>
1) 2-pin components
2) Mini-mold transistors / SOTs
3) Power transistors
4) SOP Recognition mode
5) QFP Recognition mode
6) SOJ Recognition mode
7) PLCC Recognition mode
8) Off Lead
<Connector components>
1) Single-direction Connector recognition mode
