Additional information in the Pareto diagram:

1 time filter (the set evaluation period is displayed)

2 program filter (the inspection plan set in the filter is displayed)

3 component filter (not set, and so marked with */*)

4 machine filter (not set, and so marked with *)

5 operator filter (not set, and so marked with *)

6 features filter (due to lack of space only the first filter entry is displayed;

the fact that others follow is recognized by the ellipses [,...])

7 total number of evaluated PCBs / indication of defective PCBs, result in

% (can also be switched to single panel display, in diagram properties)

8 total number of evaluated components / indication of defective

components, result in %. If a value is 0, the file si_sj.cnt or the CLE

entry #CLE_PINS is not maintained.

9 total number of evaluated solder joints / indication of defective solder

joints, result in PPM. If a value is 0, the file si_sj.cnt or the CLE entry

#CLE_PINS is not maintained.

The component type 0603R is responsible for a lot of pseudo defects, but which

analyses is it made up of? In order to get more precise information, the

procedure can be further evaluated according to analysis procedures, to get the

analysis name. When the left bar is clicked the following mask appears:

The number of defects (98), the feature (10002 = pseudo defect) and the

classification at the repair station (pseudo defect) are listed again. Choosing the

button "Template" brings up the next menu, in which defect overview according

to analysis process is chosen.

After clicking "OK" the next two diagrams are opened.

This time they are scaled according to analysis procedures.

Also here, the familiar filter settings (time filter and inspection plan filter) can be

taken over from the time axis diagram. In addition, the component filter is

automatically set to 0603R.

Meni_9 is obtained as TOP 1 and the only analysis process of this evaluation.

This results in the following question: are there several failed analysis windows

in one analysis process and if so, which analysis windows produce more

defects?

The results must be evaluated in order to give an answer, this time according to

window numbers, giving the following end result:
