After a short evaluation time, a new configuration set with two Pareto diagrams

opens automatically. These templates are pre-configured diagrams that can be

called up from other diagrams. The vpc.template file underlies them, the

possible branchings can be configured here (see appendix for a more detailed

description).

These files should only be edited by experienced users, otherwise faulty results

or a loss of functions in the cascaded evaluations may result.

In these diagrams, it can be seen that the time filter as well as the inspection

plan filter are automatically taken over from the time axis diagram.

Both templates are preconfigured so that the pseudo defects are seen on the

left side and the real defects, on the right.

This display always makes sense during optimization, to observe not only the

inspection patterns with regard to the pseudo defects they produce, but also

their effectiveness in relation to real defect recognition.

In our example the component type 0603R is to be optimized as TOP 1.

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
