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 into contact with the tooling 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:

Continue Abort

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.

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.

Score Warning

Level

During fiducial set up the score achieved after training each fiducial is analyzed.

If the score fails to achieve the accept 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 Variation Warning Level, but does not fall below the minimum accept score,

a message window is displayed, warning that the score of the 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:
