4.1.2.3 Accessibility Problems for Various Machine / Head Configurations
SIPLACE SX4 and DX4 machines:
NOTICE
In order to access the fiducials, the ACT measuring plate has to be placed rotated by
180° in SIPLACE SX4 and DX4 machines.
Thus, if an ACT placement program is defined for a SIPLACE SX4 or DX4 machine, the orientation
(position) of the board has to be adapted to 180° in the created recipe.
Figure 4-6: Rotating board orientation by 180° on SX4, DX4
If this adaption of the board orientation is not performed, the following error message (example) is
already displayed on the SIPLACE Pro Line Control GUI during specification:
Figure 4-7: Example: Error message due to unavailable ink spots
NOTICE
Due to the problems of accessing the fiducials described above, please observe:
If the ACT has to be measured on a machine of the SX-, DX-, or X-series, in front of
which one or more SIPLACE SX4- or DX4-stations are arranged in a line, the Pass-
through function has to be activated on all machines in front of the measuring machine
that require another board orientation (0°/180°).

Twin Head in Placement Area 1:
For machines with Twin Head in placement area 1 (i.e. gantry 1 and / or 4), you can use the
following adapter to ensure the accessibility of segment 2 during placement on the plate. The
adapter is placed on the front of the plate to move the plate by a total of 50 mm to the rear in the
direction of the input belt.
50 mm TWIN adapter [03085310-01]
Figure 4-8: 50 mm TWIN adapter
If you use the "50 mm TWIN adapter" [03085310-01] in the outmost panel, you must extend the
board by 50 mm in SIPLACE Pro Desk!
► For this, enter 390 mm length instead of 340 mm in the board description that you want to use
(ACT_CC02-05_CPP_TH).

Twin Head – statistical reliability:
NOTICE
► When measuring a Twin Head, pay attention to the number of placed components
per segment to ensure the statistical reliability of the measurement result.
At least 20 components per segment should be placed!
With the setup of the tray with the glass components, pickup problems may occur for some
machine types because the components cannot be reached.
► Pay attention to the tray position on the component table or in the WPC.
Variants:
► By positioning the tray on the BE table, ensure that the components can be reached in X-
direction from both segments.
As soon as the two front rows are empty:
► Stop the machine.
► Refill the components at the front.
► Set the filling level to Full again.
This also applies for the tray setup in the WPC. The components have to be refilled in the WPC
too (e.g. WPC at the SX1/2 machine) to ensure that a sufficient number of components can be
picked up by both Twin segments.
► Possibly use the Tray in Conveyor for ACT option. This ensures the accessibility in Y-
direction.
► In order to further increase the statistical reliability of the measurement result and at the same
time ensure that each segment fulfills these requirements, you can check each segment
individually.
► To do this, omit one segment at a time in the Nozzle Configuration tab of the Setup Editor
in SIPLACE Pro, so that only one segment places all 48 components.
