12.6.17.1Overview
NOTE
For the execution of test commands 3 and 8 see Section 12.6.18, Run Data Protocol (German: ADP).
You can utilize test command 4 (see Fig. 12.6.9) to check whether the laser track strikes the leads.
- The component to be measured is optically centered after test command 4 is called up. Instead of being
moved over the coplanarity sensor, it is moved over the camera., i.e., the measurement process is there-
fore simulated.
- The midpoint of the IC camera (crosshairs) corresponds to the focus point of the coplanarity sensor.
12.6.17.2Procedure (> V 403.xx)
● Execute only in case of software version 403.04 -> D:\DAT\SST.MA, speed factor:
If this value is > 200 reduce the value to 200 (= higher accuracy).

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.
