Software version SR.407.xx 01/2001 US Edition 11.11 Feeder position recognition
525
If the cluster data contains an entry for a track, the PCB camera on the feeder moves to the posi-
tion of the centering fiducial. Any centering fiducial offset determined by measurement is allocated
to this track, and added to the pick-up position during the pick-up process. 11
11.11.1.1 Restrictions
– Feeder position recognition cannot be used for WPC trays that are set up in the wafflepack
changer.
– Up to three fiducial positions can be defined for each feeder.
– Feeder fiducials on the right-hand side of the table (viewed in the transport direction) cannot
be measured on the 80F.
PLEASE NOTE:
This restriction does not apply to machines with a “sub-gantry camera”. 11
– If there is a feeder at location 118, and the fiducial position of the outer pick-up division is closer
to the X-axis travel range limit than the pick-up position, then the 8 mm S tape and bulk case
feeder cannot be scanned.

11.12 Fine calibration
11.12.1 Overview
Fine calibration involves measuring the machine’s placement offset and determining the required
correction from this value. The ‘Fine calibration’ measuring program is integrated into the SITEST
program, and a detailed description of the measuring procedure is given in the ‘Fine calibration’
instructions (article no. 00191655-01). 11
CAUTION
The SITEST program is password-protected. It must only be called up and used by Siemens en-
gineers or appropriately trained personnel. 11
11.12.2 System requirements
The following system requirements must be fulfilled in order to use the fine calibration program:11
Machine type S-20/F
4
Station computer software version 406.xx or later
SITEST version 406.xx or later
11.12.3 Measuring equipment and tools
The following are supplied as standard: 11
– Mapping plate (glass plate in a metal frame)
– Double-sided transparent adhesive film
– Lighting unit
– Magazine with glass components for the collect&place head and pick&place head with fine-
pitch vision module.
11
The following items must be ordered: 11
– Manual tray (waffle tray holder) to hold the magazine for the glass components
(article number 00116430-xx)

The following parts may be ordered if required: 11
– Magazine with glass components for the collect&place head and pick&place head with flip-chip
vision module (article number 00343704-xx)
11.12.4 Functional description
First select the placement program for fine calibration by selecting the ‘Cluster for fine calibration’
option from the ‘Options’ pull-down menu. Then process the mapping plate with the glass compo-
nents from a magazine on the manual tray. 11
After placement, start the SITEST program and start the ‘Fine calibration’ measuring program.
The placement head (collect&place head or pick&place head) will measure the current placement
positions of the glass components and compare these positions with the circular fiducials on the
mapping plate. The results are used to calculate the offset values. 11
The offset values are used to determine corrected values, which are then entered in the machine’s
machine data. 11
