The default is 0 boards.
This feature only applies while squeegees are fitted.
When a particular print stroke is being monitored, as the squeegee traverses the
image the pressure being applied is measured and recorded. Any variations in
the load being applied, as a result of insufficient tooling support or underside
components coming intocontact with thetooling are noted. Upon completion of
the print stroke, the deviation in the pressure applied over the print stroke is
determined and expressed as the tooling deviation. The tooling deviation is
calculated from the minimum and maximum values and expressed as a
percentage. If the tooling deviation exceeds the permitted threshold, as set by
the Tooling Deviation parameter in the product file, a cyclic log text file called
deviate.dat is written and the following window is displayed:
NOTE
The number of samples is the amount of pressure variations recorded during the
print stroke.
The following menu bar is displayed:
On selecting Continue printing proceeds until it is interrupted by some other
cause.
On selecting Abort printing is discontinued and the following menu bar is
displayed, to enable the board to be removed from the machine:
If the number of samples (pressure variations) during a print stroke is less than 2
or the minimum value is zero, the error message ‘Failed to determine Tooling
Deviation’ is displayed.
Display Type Sets the type of status page displayed on the monitor, options are:
Type 1; Type 2
The default is Type 1.
Fiducial Monitoring The parameter enables and disables the intelligent fiducial monitoring feature,
options are:
Smart; Normal
The default is Smart.

If Smart is selected, a Set Levels menu bar option is available.
On pressing the Set Levels key, a window opens as follows:
The Next and Previous keys move the cursor between the three parameters.
The Incr. and Decr. keys increase and decrease the value of the top two
parameters and turn the Automatic Retry ON and OFF.
The Exit key closes the window and returns to the set preferences window.
The range of values for the three parameters are as follows:s:
Score Warning Level:
Min 0
Max 500
Var’n Warning Level:
Min 0
Max 500
Automatic Retry:
Off; On
Score Warning
Level
During fiducial set up the score achieved after training each fiducial is analyzed.
If the score fails to achieve the target score by more than Score Warning Level,
an instruction box appears recommending the operator check video settings,
fiducial parameters etc.
Var’n Warning
Level
While the machine is running, the score for every fiducial located is monitored.
If for a given fiducial, the score from one fiducial to the next varies by more than
the Score Variation Warning Level, but does not fall below the minimum accept
score,a message window is displayed,warning thatthe score ofthe screen/board
fiducial is fluctuating. Fiducial relearning is advised if the problem persists.

Fiducial Search The parameter enables an auto search to be selected if a screen fiducial or board
fiducial are not found. The feature also enables a machine to run a product setup
on another machine, options are:
Custom; Disabled
The default is Disabled.
Setup If Custom is selected, an Adjust option becomes available on the menu bar:
Onselecting Adjust from the menu, a Fiducial Search StrategyWindowopens:
The menu bar changes to:
The Next and Previous keys move the cursor between the two parameters.
The Incr. and Decr. keys change the value of the highlighted parameter.
The Exit key returns to the set preferences menu.
Autosearch This parameter sets whether an automatic search can be selected following a
Fiducial Not Found Error Message. The options are:
1st Board; All Boards
The option Auto Search (F2) is added to the menu bar as follows:
Depending on the setting, the option Auto Search (F2) is available for the 1st
board or all boards of a batch, following a Fiducial Not Found Error Message.
If Auto Search is selected, the machine uses the following strategy to search for
the fiducial. The sequence continues until the fiducial is found:
1. The camera starts in the nominalfiducial position, determinedby the product
file.
2. The camera attempts to locate the fiducial within its field of view.
3. The camera stays in position and repeatedly searches for the fiducial, each
time using a different adjustment of the camera lighting.
