Cleaning the PSV7000 Machine
General Machine Cleaning
General cleaning should be performed on a weekly basis. General
cleaning includes, but is not limited to, the following listed item.
WARNING: Vision hazard! Pressurized air or debris blown
into the eyes or skin could cause bodily damage. Always use
care and wear protective eye goggles when cleaning with
pressurized air.
1. Remove all dropped devices, debris, and other materials from all
working areas.
2. With air and power OFF, remove all devices and materials that
may have fallen inside the machine.
3. Use dry, compressed air to remove all dust and debris from the
work surface and from under the machine.
4. Dust the safety doors, inside and outside, with an antistatic
cleaner.
5. Wipe the top and side panels to remove grease, fingerprints, and
dust.
6. Dust the top surfaces of the input/output modules.
Cleaning the Device Position Sensor
Fingerprints and excessive amounts of dust or other residue on the
optical windows of the Device Position Sensor will degrade the per-
formance of the sensor. The sensor is mounted on the bottom of the
PNP head.
If the sensors are not providing a good image, it may be an indicator
that the windows need cleaning.
For instructions to turn
OFF the air, see page
4-9.

Check the Sensor Windows
To check to see if the sensor windows are currently providing a good
image:
• Open the Gantry window in the AH700 and click Check Image.
The wavy line should be smooth. If it is jagged, clean the win-
dows. For more information and an image, refer to the on-screen
Help.
Clean the Sensor Windows
Requirements
• pre-moistened wipes (PN 5700410), or
• lens tissue (PN 570041)
To clean the sensor windows:
1. Brush dust off the sensor windows using a camel-hair brush
such as an artist brush.
2. Remove fingerprints or other oily deposits; either use pre-moist-
ened wipes or moistened lens tissue or cotton swab with a small
amount of isopropyl alcohol.
CAUTION: Product damage hazard! Wiping back and forth may
re-deposit the debris and may damage the window glass. Wipe in
a single direction, lift and repeat.
3. Wipe each window once IN A SINGLE DIRECTION.
4. Using a dry tissue or swab, lightly wipe each window IN A SIN-
GLE DIRECTION to remove any remaining alcohol or acetone
residue.
The cleaning wipes are
part of the Self-Service
Spare Parts Kits.

Pick and Place Probes
The workspace Pick and Place head has two probes which require
periodic maintenance. The headings below describe maintenance.
Checking the Probe Tips
Worn or damaged probe tips on the PNP head can cause dropped
devices and placement problems.
1. Check the probe tips for cracks or tears. If necessary, replace
with a probe tip of the same size.
2. Test the probe tip—
2a. At the Setup window, click System > Gantry.
2b. Click the Vacuum switch to ON.
2c. Open the safety door and place a device on the target probe.
2d. If the vacuum does not firmly hold the device, replace the
probe tip with a probe tip of the same size.
Checking the Probes
Check that each probe is not loose. Tighten the set screw on the stem
if necessary. If you suspect or hear an air leak (and your style of probe
has a set screw):
1. Remove the set screw on the probe stem.
2. Pull off the probe stem and check the O-ring. Replace if neces-
sary.
3. Reassemble.
Cleaning the Probe Tips
To clean the Probe tips:
1. Move the PNP head to a convenient position by clicking one of
the yellow labels on the Gantry window. The Tool position is rec-
ommended.
2. Open the safety door.
3. Wipe the tip
with alcohol wipes (Data I/O PN 570-0410-001) or a
damp cloth.
Note: Do not touch the probe tip with bare hands. Finger oils can
cause small devices to stick.
