11.1.3 Replacing spare parts
The wafer support can remain installed when spare parts on it are replaced. You can fit either a
wafer support for 12" or for 8" wafer frames.
11.1.3.1 Replacing the complete wafer support
► Move the wafer table to the wafer change position.
► If an LDU is fitted, you will need to remove it.
► Shut down the SWS GUI and switch the machine off.
CAUTION
Disconnect the SWS from the compressed air supply.
► Switch off the compressed air supply.
► Disconnect the SWS from the compressed air supply.
► Open the cable clamps and unplug the connection and ground cables.
Fig.350: Replacing the complete wafer support
► Remove the four fastening screws (2) and lift the wafer support out of the locating pins.
► Pay attention to the black O-rings under the wafer support rails. The O-rings must stay in the
openings and may not be lost. Replace with new ones, if necessary.
12" sensor monitor
The sensor (3) monitors whether there is a 12" or 8" wafer support fitted.
► Check the input signals of the proximity switch.
► In the toolbar, select the button Manual Settings
.
► Go to the Manual Settings view and select the button Manual Subsystems and then select
IOs (see 14.2 "Manual settings" [}358]).
► Select the Wafertabletab.
ð The displays will shine:
DI11 12" adapter
The connection cable is clamped to the large wafer table adapter board.

11.1.3.2 Turning the wafer locking strip by 180 degrees (option for 8" wafer support)
There are two versions of the wafer locking strip (1). The wafer locking strip for the 12" wafer sup-
port can not be turned. The wafer locking strip for the 8" can be rotated by 180 degrees and then
fitted.
This makes it possible to process wafer frames with different locking positions and rotation posi-
tions(3) or(4) .
Fig.351: Turning the wafer locking strip
► Unscrew the two knurled screws (2) holding the wafer locking strip (1).
► Carefully lift off the wafer locking strip, rotate by 180degrees and fit again.
► Pay attention to the black O-rings (5) under the wafer locking strip. The O-rings must stay in
the openings and may not be lost. Replace with new ones, if necessary.

11.1.3.3 Setting the wafer support width
The width of the wafer support strips can be adjusted in accordance with the wafer frame. There
are two different positions (pin inside or pin outside).
Fig.352: Wafer support strip - adjusting the width
Both wafer support strips must be fitted in the same way. This means that both pins are either in-
side or outside. The diagram shows a wafer support strip with one pin (2) on the outside.
► Remove the knurled screw (1) from the wafer support strip (3). Remove both wafer support
strips.
The pin (2) must be either on the inside or outside of both wafer support strips.
CAUTION
Take care of the pneumatic hoses and cables
► Take care of the pneumatic hoses and cables. These may not be pinched or rubbed
against unprotected edges.
11.1.3.4 Replacing the driver on the clamp
The driver is the attachment for two different thicknesses of wafer frame and is fitted to the clamp.
Fig.353: Replacing the clamp driver
Two different drivers for metal and plastic wafer frames.
●
[00386221-xx] for thin, metal wafer frames
●
[00386560-xx] for thicker, plastic wafer frames
► Remove the two screws fastening the driver to the clamp and replace the driver.
► Align the driver with the two fastening screws so that it is centered and parallel to the wafer
frame (within the play of the drilled hole).
