1. Vacuum LED - Illuminates to indicate vacuum is active.
1
2. Theta Adjustment Knob – Rotates the component to allow rotational alignment.
1
3. Fine Z-Axis Adjustment Knob –Raises and lowers the position of the component while suspended by
the vacuum cup. The importance of height adjustment, in reference to focus, will be discussed later
in this manual. Note: Component will be placed incorrectly if height is wrong.

4. Z-Axis Control Knob - Rotating this knob clockwise raises the vacuum head, while rotating counter-
clockwise lowers the vacuum head.

5. Light Adjustment Ring (Iris) –Controls the amount of light entering the camera.
1
6. Focus Adjustment Ring – Adjusts the focus of the image projected onto the monitor.
1
7. Zoom Adjustment Ring – Varies the zoom ratio of the lens.
1
8. Beam Splitter Knob - Splits the observed image so that only the corners of the component and PCB
can be viewed and magnified in order to make fine adjustments and perform accurate placement
inspection. This function is not present on CSP-3500 Series Systems.

9. Center Adjustment Control Knobs - These two knobs are used for adjusting the projected image so
that it is centered in reference to the monitor.
10. Tooling Plate Holder/ Component Slide - The adjustable MPVB tooling plate is mounted here. This
is used to introduce the component into the optical path of the prism and ensure that component
pick-up is centralized in reference to the vacuum pipette.
11. Vacuum Selector Switch - When this switch is in the “microswitch” position vacuum is controlled
by the microswitch located in the vacuum head. When in the “footswitch” position, vacuum is
controlled by the FS-24 Footswitch.
12. Prism Slide Knob - Pulling this knob towards you accesses the prism to view the component and
board simultaneously. Pushing this knob
forward retracts the prism to allow the
component to be placed.
Note: An image cannot be viewed on the
monitor when the prism is retracted.
13. Z-Axis Stop - The position of this screw
determines how far the vacuum head will
travel upward or downward in the Z-Axis.
14. Foot Switch Receptacle - The FS-24
Footswitch connects to this receptacle.
