Procedures Performed Every Day
Clean and Check the Sockets on the Socket Module
1. Use clean, dry compressed air to remove dirt from the sockets.
2. Check the sockets for wear and replace if necessary.
NOTE: The socket replacement cycle depends upon the type of
socket used and the socket manufacturer. For the most current
replacement guidelines, refer to the documentation shipped with
your sockets.
Procedures Performed Every Week
Clean the General System
General cleaning should be performed on a weekly basis. General cleaning
includes but is not limited to the following:
1. Remove all dropped devices, debris, and other manufacturing materials
from all working areas.
2. Remove all devices and manufacturing materials that may have fallen
inside the system.
3. Use dry compressed air to remove all dust and debris from the table
surface, under the machine, and from all other visible areas.
4. Dust the safety shields, inside and outside, with an antistatic cleaner.
5. Wipe the top and side skins to remove grease, fingerprints, and dust.
6. Dust the top surfaces of the input/output modules.
Clean the Vision Camera Lens
1. Dry compressed air—
Use dry compressed air to remove all dust and other foreign material
from the camera lens.
2. Lens cleaning tissue—
Clean the lens using a lens cleaning tissue dampened with isopropyl
alcohol if required.
Check the Device Probe Tips
A worn or damaged probe tip on the PNP head or the tape output PNP head
(if installed) will cause dropped devices and placement problems.
1. Check device probe tip—
1a) Check the device probe tip for cracks or tears in the rubber.
1b) If necessary, replace with a probe tip of the same size.
2. Verify vacuum on new probe tip—
2a) From the Setup window, click System.
2b) Click Gantry to open the Gantry window.
2c) Click the Vacuum switch to ON.
2d) Place a device on the probe tip.
2e) If the vacuum does not firmly hold the device, replace the probe tip
with a probe tip of the same size.
