6.1.1 Manual Alignment
Manual Alignment is generally used when there are no eyepoints for Auto
Alignment. It may also be used when making one or two cuts on a single
Workpiece in order to test the results of a Recipe before it is put into use.
Likewise, Manual Alignment is a part of the Teach Alignment procedure
(see
section 6.1.3.2).
Once Manual Alignment has been performed, the Workpiece can be cut,
using the parameters defined in the Recipe.
Manual Alignment comprises the following steps:
• Aligning the Workpiece, to ensure the Streets are parallel to the Blade
• Defining the Cut Position.
6.1.1.1 Aligning a Workpiece
The first step in Manual Alignment is aligning the Workpiece parallel to
the Blade, by aligning the Reticle in the Field of View (FOV) with a
selected Street.
To Perform Manual Alignment:
1 From the Manual menu, select Vision > Manual Alignment,
or click in the toolbar. The display automatically switches to the
Video Workspace, where the first step to be performed by the User is
displayed in the Wizard.
2 Follow the direction given in the Wizard.
3 Position the horizontal line of the Reticle along the edge of a Street on
the Workpiece using either the X/Y-Axis Controls or by double-clicking
Note: As Manual Alignment is performed by the operator of the System, the
accuracy achieved depends upon the skill of the operator and is therefore
subject to human error.
Note: If a cut map for the wafer already exists, the system goes to the defined
cut position. To perform the alignment manually click Back.
Note: Adjust focus and illumination
