7.9.2.2 Reference profile creation
In Create Profile tab, enter the differente values of the profile to create.
1.
Define the position, the size and the orientation of the Profil-
er™. On the image, the Profiler
area appears in orange.
2. Define the light level.
3. In Align position on area, define the realignment op-
tion:
Select
Adjust side position to realign the profile with the side of the lead,
Select
Adjust perpendicular position to realign the profile with the end of lead,
Select
Set position on CAD position to place the profile on the CAD coordinates.
4. Choose a good lead and press the Test pin button to see the profile.
5. Click on Set Profile button to learn the profile reference.
The Profiler
can be placed on lead or on
joint, where there is a maximum of difference
between good leads and bad leads.
Profile become blue when you learn it. It became the reference for the Global
tolerance tool.

6. Press Propagate >>> button to propagate Profiler
characteristics (size, position, ori-
entation and reference profile) to all leads of the sides or component.
7. Click on Test all pin of the side button to see all profiles of the side.
At this stage, Profiler
is created. Now, tolerances which include all good lead/joint
(for
Global adjustment and Lead to lead tools) must be determined.
7.9.3 Standard mode
7.9.3.1 Tolerances of global tolerances tool setting
To set the tolerances of global tolerances tool, go in Tolerance tab.
In
Profile area (A), enter a value in Tolerance fields and press Reset button to display
the up/down tolerance lines at wanted value.
This value is in gray level. Tolerances are
constructed in relation to the reference
profile.
Tolerance (B) can be adjusted along the
profile:
1. Click on the point to move, and move it with the mouse.
2. Press Shift button on keyboard to move several points (10) at same time.
3. Use Up/Down arrows to move tolerances and keep manual modifications.
If you click on Test pin button, only the selected lead is displayed.
