4.2.3.3 Preparing for Calibration

To ensure that customer setups do not need to be changed, a black calibration tool carrier is moved into

PCB conveyor 1, is optically centered and clamped into place, the presence of the white balance

calibration tools is checked and illumination calibration (white balance process) is started.

NOTE:

The XML files for the white balance process are created before beginning measurement. To

view the data for the current calibration in the XML file, perform the balance process (with 603/

604.01) again; without saving the data when you exit SITEST. The files will then be in the folder

C:\SR-Daten\FCCS

X Go to

Calibrate illumination

in the

Calibrate

Entire Machine

menu.

X In the calibration menu for the entire machine,

you can specify the camera for which the

process is to be conducted (all/placement

area1/placement area2/head).

X The width adjustment will then automatically

set the width of conveyor lane 1 to the width of

the tray.

X The nozzles required for the illumination

calibration will be shown, as will the current

head setup. You may need to terminate the

menu, in order to configure the nozzles at the

head or to pick them up from the nozzle

changer.

X If you have a second placement head at the

gantry, the setup for this will be shown in a

separate window.

X The SITEST software will now request that

you place the calibration tool carrier into the

input conveyor. (Do not push in as far as the

input conveyor sensor!) Confirm each step

with the OK button. In this step, the tray is

moved into the processing area and is

clamped into place.

4.2.3.4 The Illumination Calibration Process

X The PCB camera is positioned to check the presence of the calibration tools. Fiducial recognition

determines whether all the calibration tools are present.

X The PCB camera centers the 3 fiducials for

position recognition of the calibration tool

carrier.

X Illumination calibration is now performed for

the PCB camera.

(see diagram of standard PCB camera)

X Tray position recognition is performed again.

X The gantry placement head picks up its

appropriate calibration tool for the component

camera.

X The calibration tool is placed under or above

the respective component camera, the

balance process is performed and the

calibration tool is returned to where it was

picked up from.

(Here you can see a video image of the C&P6

component camera.

X The calibration process is repeated for the

cameras of the second gantry in the

placement area or for the second placement

head of the gantry.

4.2.3.5 Continuation

X Once the calibration process has been completed, the technician needs to confirm this and then

have the carrier transported through to the output conveyor.

X When exiting SITEST, a message will be issued, informing you that machine data still need to be

saved. If you confirm this message, the values determined will be written to the camera EPROM.

X For report purposes, an XML file is created for each camera, in the

C:\SR-Daten\FCCS

folder.

This file is assigned a time stamp in its file name.

X In an ideal case, this file should be created before starting calibration.

However, the technician currently needs (SR/MC 603/604) to manually create these files in the

individual camera menus and select the respective storage paths (e.g.

C:\SR-Daten\FCCS

X From SR/MC SW version 605, the respective EPROM data is saved before and after the white

balance process, in a file in the

C:\SRDaten\FCCS

folder.

The file name contains the following:

- gantry name

- camera type name

- before/after calibration

- date stamp

Example:

Gantry_1_CameraID_25_after_FCCS_2008_06_06_14_01_28.xml

The illumination tool carrier is moved into

placement area 2 and the calibration process is

repeated, according to the machine configuration.

camera option for the TWIN/P&P head.
