5.12 Placement sequence for all heads
As of software version 505.xx, placement sequences are supported for all head types.
In order to achieve ideal placement performance, the placement sequence is generally calculated
and specified prior to optimization. If, however, components are to be placed above each other or if
the placement positions are very close together, the user can specify the placement sequence for
these components by changing the placement level. During the subsequent optimization of the
placement sequence, these definitions are taken into consideration and remain unchanged.
The specifications for the placement sequence are transferred to the station using the placement
program generated in SIPLACE Pro (file "aktuell.nu").
5.12.1 Restrictions
- The placement performance is no longer optimized if the placement sequence is specified in
SIPLACE Pro by defining placement levels.
- Only one placement level is placed in each head cycle -> reduction of placement performance.
- Version 505.xx of the software must be installed on all stations in the line.
5.13 Face-down recognition
When chip components are picked up, it is possible that individual components are picked up on the
underside by the nozzle. If the vision system detects this, the component is rejected in order to avoid
incorrect placement. The top and underside of the components must be clearly different in terms of
color in order to allow recognition of face-down (flipped) components.
The vision system determines the brightness level (possible values: 0 = dark through 255 = light) in
a rectangle in the center of the component.
- If the measured value is above the specified brightness threshold, the rectangle is recognized
as "light".
- If the measured value is below the specified brightness threshold, the rectangle is recognized as
"dark".
The value measured on the underside of the component is now compared with the specified
threshold. It is thus possible to determine whether the component was picked up with the underside
facing upward (i.e. flipped) or correctly.
The brightness threshold is either set manually or determined by teaching flipped components if the
difference in brightness between the two sides is low. It is also necessary to specify whether the top
side is darker or lighter than the underside.

-
Setting: it is light in the camera image
This setting is used for components where the upper side is lighter.
If the component is shown as light in the camera image, it is taken to be flipped and thus
rejected.
- Setting: it is dark in the camera image
This setting is used for components where the upper side is darker.
If the component is shown as dark in the camera image, it is taken to be flipped and thus
rejected.
5.14 Synchronous dual conveyor with PCB barcode
As of software version 503.01, the use of synchronous dual conveyors is supported. Software
version 505.01 now allows the use of synchronous dual conveyors with PCB barcode operation.
The following workflow/conditions also apply to PCB barcode operation:8
- Each board must have a barcode.
- The barcodes are read as the boards travel into the machine.
- Both barcodes are transmitted to the programming system which then selects the appropriate
recipe from the recipes configured. The panel information for this recipe is transmitted to the
station.
- If the programming system does not contain a recipe for the barcodes that have been read, the
boards are simply transported through the machine.
If the board has no barcode, or the barcode cannot be read, the station opens up a dialog box and
prompts the operator to enter a barcode by hand.
5.14.1 Restrictions
- No ink spot recognition
- No whispering down the line
- No "virtual ink spot" SOKO
