a. Recipe:
This shows the recipe (measure plan) as an image, which is used in the project.
This is the only tab which is not depending on the filter settings above.
b. Scan:
This view is only active in the printer mode “Single”!
The evaluation is the same as with placement machines.

The ”number of Valid:”
means the number of

e. Value table:
In this table all measured values are listed in numbers.

a. Zeigt das Ergebnis der selektierten Messung, abhängig von den Filtereinstellungen
oberhalb.
In a printer project, in printer mode „Point2Point“ the Offsets of all the activated
measures are displayed („Board2Board“-view).
Evaluiation lines:
- Sigma limits (green lines) show, at which offset value the given accuracy class (e.g. 6
Sigma) is reached with the present measured values.
In the example above, the accuracy class of 6 Sigma (cmk >2.0) is already reached at the
value +7µm/-7µm in X direction. The specification limits are +/- 20µm (red Line).
- Regression Line shows the offset trend (flowing average) of the result.
- Mean and Median: Both average lines can also be displayed in one diagram. Different to
the regression line, these lines are always straight leveled.
