7.8.2 Custom tab
The Custom tool is based on the
QFP tool. When opening the custom
edit page, all the treatment areas are
automatically placed according to the
component features.
Check that these parameters fit on
real components.
Load a real image on the camera dis-
play and adapt the parameters.

7.8.3.2 Parameters
Tick Active processing (A) to active the
component body detection.
In Body color (B) select the color of the
component body (dark or bright).
Select the Light level (C) used for the
body detection.
In Angle detection section, define the pa-
rameters for the component angle detec-
tion. The body angle detection is done
with an helicopter Edge:
Select the Side (D) of the component you
want to use for the angle detection.
Offset XY, Width and Length (E) of the
edge window.
Angle and Step (F) of rotation for the ro-
tating edge.
Contrast and Filter Half-size (G) edge
tool parameters for detection.
In Width and Height detection sections,
define the parameters for the component
width and height detection.
Expected width and Tolerance (H) of the
body width.
Contrast and Filter Half-size ( I ) edge tool parameters for detection.
Offset XY, Width and Length (J) of the edge window.
Press TEST (K) button to execute the 3 previous detections and see the results.
Expert mode (L) allows to access all parameters of this window. If this window is not
ticked, only some parameters are displayed.
The width and height body detection are done with 2 double transitions edges.
The edge windows are realigned with the results of the previous step (the 1st
step is the Angle detection).

Without Expert Mode
The option Expert mode (J) is not
ticked.
Select the tab to edit the wanted side of
1st component.
Select the pin number (
A
) you want to edit.
The Pitch (B) allows you to increase or
decrease the pitch size between pins.
With Offset all leads position (C) you
can modify the offset of all leads.
Tick Apply to all sides (D) to apply
these modifications to all sides.
Click on Display (E) button to see
modifications in the image window.
Increment (F) determine the value of
increase (or decrease) of pitch and off-
set of leads.
