2.5 Registering the Component Number Model
Calculate the model for each component number and register the component information in the
library.
Details of the information registered are the color parameter information needed for the 2D
inspection logic and the height information and projector’s light intensity needed for the 3D
inspection logic.
Model calculation refers to the automatic extraction of the characteristic parameters to detect
the colors and shapes of the component and electrodes.
1.
Select the "Extract Parameters (Auto)" tab.
2.
Select the component number in the Component Number List.
The thumbnail images of the currently selected component and all
the components with the selected component number are displayed
in the image display area. If you select a component number
belonging to a component number group, all the thumbnail images
of the component number group are displayed.
When the button is (locked), click to change the
component number state to not locked .
Only the image for the component numbers with the right end
progress signal bar lit ( or ) can be selected. To redo
the model calculation for the comonent numbers with lit right
end signal bar, click [Delete].
Click button in the Image Operation tool bar to display a
list of component thumbnail images in the image display area.
Refer to "2.1.2 Configuration of the Editing Screen" for the
image operation buttons.

3.
Check each component thumbnail image to determine if the image
and windows are aligned. If not, adjust the positions and sizes of
the windows.
Click a component thumbnail image or a component in the
Component Image List to select it. The field of vision on the PCB
image moves to the selected component.
Size adjustment is only possible for land windows.
The position of the Component Body Window and electrode
windows cannot be adjusted separately.
Refer to "2.1.3 Image Display Area Operation" for the image
display area operation.
4.
Select the component thumbnail image to use for model calculation
and click the corresponding checkbox in the Component Image List
or the checkbox next to the component thumbnail image.
The checkboxes for the components selected in inspection
registration are selected by default.
It is automatically judged by the destination setting of the
component of the inspection program which captured the image
if the checkboxes on the applicable image list are checked ON
or OFF. The components not included in the destination
program are checked OFF. For the components included in the
destination program, only the images of the inspection PCB
captured by the destination program are checked ON. However,
if images are present only in the master inspection program, the
PCB images in the master inspection program are checked ON.
Multiple images can be selected. Clicking the checkbox at the
header in the Component Image List can select all the images
(checkboxes) simultaneously.
For more precise extraction of characteristic parameters,
select a good component image for the model. If there are
multiple candidates with a slight difference e.g. in the electrode
color, select them all to enhance extraction precision.
5.
Repeat Steps 2 to 4 for the component numbers with no image
specified yet.

6.
Click [All Component Numbers Model Registration]. Model
calculation will be automatically performed and models will be
registered to the library.
When performing model registration for one component number
displayed on the screen, click [Registration].
When the image is not selected, the [Registration] and
[All Component Numbers Model Registration] are not
available.
7.
To learn with more model images as in mass production images,
click [Learn Again].
Pay attention that re-learning overwrites information already
configured, such as a color.
8.
To learn height again, clicking [Calculate Height] automatically
calculates the height again. To learn the height again for all
component numbers, click [Calculate Height for All Component #].
[Calculate Height] does not affect information already
configured, such as a color.
Use this function when learning height to use the 3D logic.
Perform the PCB test to calculate the height of the component
number. The median of the PCB test result is used to calculate
height.
