6|Function description
ð The PCBs will only be fed into the module it the next module is empty. This
way, the PCBs are prevented, for example, from remaining too long in the
module due to a jam. However, this function can extend the cycle times.
Permanently fixing PCBs
ü To permanently fix PCBs during processing:
a) Activate the [Fix horizontal permanently] checkbox.
ð The PCBs are aligned in the module and then laterally fixed until processing is
completed. If the checkbox is not activated, the PCBs are only aligned and then
released again. You can activate this function separately for all available fluxer
and soldering modules
Manually compensating for the PCB deflection
Due to the heating and weight of the components, the PCBs get bent during pro-
cessing. Thereby, the distance [Z] from the solder nozzle to the soldering joint
changes. The machine corrects this error if an offset value is specified. The control-
ler takes into account the deflection and corrects the distances accordingly.
ü To compensate the [Board deflection] in machines without deflection measure-
ment:
a) Select the current soldering module from the [Data source] dropdown menu.
b) Determine the deflection of the board at the point of greatest deflection. This
is generally a point in the middle of the PCB.
c) Enter the deflection in [mm] into the [Correction] input field. Enter a positive
value if the board bends downwards. Enter a negative value if the board bends
upwards.
ð The deflection of the board is now taken into account by the controller and the
[Z] distances to the solder joints are corrected accordingly.

6.9.10 Settings of the Versaeye inspection system (option)
If the Versaeye inspection system must be used in the soldering program, it must
be configured in the machine control.
With regard to this, please also read the Versaeye inspection system (option)
[}269]chapter.
In order to use the Versaeye inspection system in the soldering program, the Exit
unit must be enabled in the soldering program.
Activate the [Exit unit] in the soldering program
ü Activate the [Exit unit] in the soldering program:
a) In the [General soldering program data] dialog, enable the module checkbox at
level 1.
ð The [Exit unit] module is now enabled and can be used in the soldering pro-
gram.
Setting the conveyor speed
ü To set the conveyor speed:
a) In the [General soldering program data] dialog in level 3, click on the input field
of the conveyor section.
b) Enter the conveyor speed in [%] of the maximum possible speed value.
ð This is the speed at which the board is conveyed into the next module.
Performing extended settings in the [General additional data] dialog
ü To perform extended settings:
a) Open the [General soldering program data] dialog.
b) Below Level 6, click on the
button in the corresponding module.
Open the [General additional data] dialog. The yellow square indicates how often
the dialog has already been opened.

6.9.11 Working with deflection measurement
If your machine is equipped with deflection measurement, you can use this func-
tion to automatically compensate for the printed circuit board deflection. A sensor
reads the height [Z] in two pcb points. The controller uses said readings to calculate
the deflection and correct distances accordingly.
ü To set reference positions:
a) Enter a Reference position [X] and [Y] each time. The pcb should not deflect in
this position, and no component should be positioned on the lower side of the
pcb. This position should preferably be on the pcb edge.
b) Enter a Measuring position [X] and [Y] each time. In this position the pcb
should be deflecting at the most, no component should be positioned on the
lower side of the pcb.
c) Enable the [Use] checkbox.
ð Only the controller takes into account the pcb deflection. Before the actual sol-
dering process, the sensor compares the [Reference position] with the [Meas-
uring position] and determines the deflection. In this ways the machine cycle
time can be extended.
