CAUTION O
It is not permissible to change the entered speed factor in the case of V 404.xx.
● Restart the machine to transfer the revised data.
● Activate the submenu “Test command 4” in the menu “Software options”
● Turn the cycle mode on.
● Move the PCB into the center conveyor (placement conveyor).
● Pick up the component during the cycle mode.
The component is optically centered after being picked up.
● Use “ALT 8” to switch the camera to the monitor.
● Move the component over the IC camera:
The component is moved to a position at which the first row of leads is over the IC camera.
During this process, the IC camera simulates the coplanarity sensor.
The cross in the center of the screen represents the focal point of the coplanarity sensor.
The start and end positions of the scanning track are shown on the monitor.
NOTE
The order in which lead rows are positioned over the IC camera as shown in Fig. 12.6.10 corresponds to the
order of positioning and/or scanning during the coplanarity measurement.
During the simulation of the measurement, the error message "Measurement error! Coplanarity cannot
execute command" is reported -> you can ignore this message.

● During the next cycle the measurement of the second row of leads is simulated. Now you can check the
position of the last lead in the row, as above.
-> Where components with long rows of lead or wide spaces between leads are involved, teh start and
stop position may be located outside teh camera´s field of view and it may therfore be impossible to dis-
play tehm on the screen.
● Conduct this test for all four sides (see Fig. 12.6.10).
● If the leads are not struck exactly during this process (see Fig. 12.6.10, “Presentation Top Right”) check
the GF description (see “Operating Manual for UNIX Line Computers”) and, where applicable, the calibra-
tion.
● Abort the placement and remove the PCB.
● Deactivate the clock mode, turn off the test functions and exit the menu.

Once test command 3 or 8 in the SOFTWARE OPTIONS menu (see Fig. 1.8.1) is activated, the coplanarity
measurement of a component is performed, including the recording of the measured values. During the
execution of test command 3 a detailed file with the measured values of each individual lead is recorded too
and the final results are determined. With test command 8 only the final result if recorded.
The data is stored in the file ADP.out (Path: D:
\log
\ )
and can be displayed with editor (see Section
12.6.18.2).
12.6.18.1 Output of an Error Message while Executing the Test Command:
During the following measurement the following error message is issued:
"Measurement error! Coplanarity cannot execute command"
-> You can ignore this error message.
Cause of this message:
During simulation the component ist moved over the IC-camera, not over the sensor
Informations for errror mesages during the placement sequence (incl. this error message)
you can find in the Service Manual SIPLACE, Chapter Coplanarity (Option).
NOTE
Afterwards you see a printout of the ADP.OUT file. As a simplified example, the measuring process was per-
formed with one component with just 2 rows of 30 leads each. Per lead, the measured values , e.g., 39xxx,
occur 15 to 17 times. The measurement sequence is shown in Fig. 12.6.17.2.
It is identical with the sequence during the execution of test command. The ADP file printed out below is only
appears at the screen in german. Refer to Section 1.8.8.3 for translation.
