6.6. Affixing the Payload to the Stage
The payload should be flat, rigid, and comparable to the stage in quality. For valid system performance, the
mounting interface surface should be flat within 1 µm per 50 mm.
The stage tabletop features tapped holes for mounting the user’s payload. These are the only features that
should be used to attach a payload to the stage. Mounting-hole sizes and patterns will depend on the stage
model ordered; see the CAD drawings in Section 10.6 for details.
Prepare the payload mounting surface and the stage table with precision flat stones to remove any burrs or high
spots. Clean the payload mounting surface and the stage table with the appropriate cleaners (isopropyl alcohol).
For optimum performance, the payload center of mass should be centered on the stage tabletop. If the payload
is not centered, the rotating mass will not be balanced about the axis of rotation. Imbalance, especially at higher
rotational speeds, can cause vibration, excessive error motion, and possibly damage to the stage.
Do not attempt to modify the stage table in any way. Customer modifications may damage the
stage.
The screws used to attach the payload to the stage table should not thread into the stage
tabletop any more than the depth shown on the CAD drawing. Longer screws may damage the
table.
Do not overtighten the payload mounting screws.
Do not exceed the maximum payload specified for the A-62x stage.
6.7. Multi-Axis Configurations
Multi-axis configurations of the A-62x series stage are not available at this time without customization. Please
contact PI for a quote if you require a multi-axis system.
