9.3.5 PCB Mapping
With the PCB mapping the linearity of the X- and Y-guidance for PCB-camera movement is measured
in the placement area. The PCB-camera center the cross fiducials on a high precise glass plate. This
mapping plate has been measured with a measuring device and the dimensions are taken into account
during the mapping procedure.
9.3.5.1 Preparation for Mapping
X At the single conveyor the SITEST move the transport sides to 508mm wide the mapping plate is 90
degree turned.
X At dual conveyor the SITEST SW move all the conveyor sides depend of the conveyer which is
selected the conveyor for mapping to 450 mm wide the other track to 0mm. This enables you to use
the dual conveyor as single conveyor. The Mapping must be carried out for the maximum conveyor
width.
X To prepare the board and RV mapping procedure, the SITEST SW automatically sets the conveyor
sides, so that the mapping plate fits into the relevant conveyor side.
X The C&P12 must be equipped with nozzle type 956.
X The calibration tools are in the calibration pocket.
9-7: Position mapping plate and conveyor side position for single and dual conveyor
9.3.5.2 Procedure:
X Place the mapping disk or CD-ROM in the station computer and copy the measurement data for this
mapping plate.
X Put the mapping plate in the input conveyor for placement area 1 or in the intermediate conveyor for
placement area 2.
X Now appears the teach menu to teach the fixed PCB corner OK.
X PCB mapping is running.
X Then the gantry axes move the camera up to the start position. The light-colored fiducial cross will
now be centered with the help of a synthetic image.
X This results are set for the nominal coordinates. 40.000 µm in X- respectively Y- direction added for
the next fiducial nominal position.
X The deviation of the structure to this theoretical position is measured.

9.3.6 Head Mapping (C&P Head)
Head mapping measures the linearity of the C&P head X/Y guidance.
The C&P head places the calibration tool precisely on the default positions of the mapping plate. The
PCB-camera measure the placement accuracy of this placements for the whole placement area.
After the PCB mapping the placement head place at the theoretical positions of the PCB-mapping
the calibration tool.
The PCB camera measures the placement accuracy with the help of the 4 calibration tool fiducials
on the calibration tool upper side.
NOTE:
All described automatically calibration steps above, can you do manually step by step under the
sub menus (see chapter 12.1).

9.3.7.1 Transport Menu

Legend
1.
Changing the conveyor width
(only for lane 1, if dual conveyor):
You will see a submenu, in which you can select
Widened
or
Not widened
(standard width).
Widened means that lane 2 is moved together (to the limit switch), while the fixed side for lane 1
remains in its position. (max. width of lane 1 = 380 mm)
If point 4 is selected first (extra wide) this gives a max. width for lane 1 of 430 mm.
2.
Change transport mode
:
This function is used to configure the option
Long Board
.
Next menu:
normal PCB/ long PCB
3.
Show stop positions
:
shows the number of position in PA 1 and PA2, additional the offset depend on the standard position
(PCB Reference- corner). The offset for the option
Long Board
is set by SIPLACE Pro.
4. This enables you to move the fixed conveyor side in its standard position to accommodate standard
or extra wide boards (values from the conveyor control machine data).
Extra wide means that the fixed side is moved up to 26 mm. (dual conveyor lane 1 and lane 2 =
242 mm, flexible dual conveyor lane 1 = 430 mm, single conveyor = 508 mm)
5. Point 5 and 6 only with Siemens Service password active! The fixed conveyor side (
left, right
) can
be taught.
6. Save the teach data from point 5.
