1. Size-Driven Mode

See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.

This measurement mode can be recognized by rotating windows around the edges of the component

Procedure

I. Within the search window profiles are shown in x and y directions. By means of the gradients derived from

these and a geometric filter the approximate position of the component is determined.

II. Windows rotate around the edges of the component. For each window the profile and the gradients are

determined. The sum of the gradients is a measure of the agreement of the window angle with the position

of the component.

If the sum of the gradients reaches a maximum, the angular position of the component has been deter-

mined.

III. Under the angle determined in II the first step (I) is repeated. Now the position of the component can be

determined more exactly on the x and y axes.

Rectangles:

green: x and y location tolerances

orange: Component dimensions and tolerances sent from the station

blue: Search window for position recognition

Comments

1. The position in which the component was found must lie within the green rectangle or the compo-

nent is not mounted.

Applies to all measurement steps!

2. The component must be located inside the orange window or the measurement results should be

questioned.

3. The search windows should have the same alignment as the component and be larger than it.

Lines:

red: Component edges found

Comments:

The red lines are often covered by others and it may not be possible to recognize them.

Overlay:

grey: Profile in the respective direction of integration

blue: Gradients from the above profiles

yellow: Result of the geometric filter

red: Interpolation limits for determining position

light blue: Result of interpolation -> position

Comments:

The interpolation result should be found around the maximum of the geometric filter.

Cross:

white: Result of position recognition -> x, y, angle

Diagram:

Result function of the angle search (rotating windows).

Comments:

The minimum (corresponds to the maximum of the sum of the gradients) gives the non-interpolated

relative position. The final result (through interpolation) is displayed by a light blue line. The accuracy

of the diagram is limited by the resolution of the monitor.

2. Row-Driven Mode

See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.

This measurement mode can be recognized by a number of windows around the middle pins of a row of pins.

Procedure:

I. Position recognition takes place via the formation of profile vertical to the direction of the pins. This is used

to determine the edges of the component.

II. With two additional windows the relative position of the component can be determined.

Rectangles:

green: x and y location tolerances

light blue: A. 2 to 4 search windows for position recognition. These are located around the middle

pins of each pin row.

B. 2 Additional search windows for angle measurement. Both windows lie in the same pin

row.

Star:

orange: Result of the first scan procedure

Comments:

The star indicates the position in the pin direction. Depending on the measurement algorithm used the

middle or the tip of the pin will be displayed.

3. Corner-Driven Mode

See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.

This measurement mode can be recognized by the windows around the entire pin row.

Procedure:

●

Determine the position in the direction of pins in the light blue window

●

Determine the position vertically to this in the dark blue window

●

Calculate the position of each pin group and thus of the component

Rectangles:

light blue: Search window for the position in the direction of pins

dark blue: Search window for the position vertically to this

green: x and y tolerances

Star:

orange: Result Location of the group concerned

Comments:

Depending on the measurement algorithm selected the middle or the tip of the pin group in the direc-

tion of pins will be displayed.
