► With the Set illumination option you may check

the illumination setting.

Normally, the pre-set values should not be

changed!

► Under Stereo: Fine Height View you may check

the result of the stereo measurement.

Ensure that the THT pins are in the focal plane

(yellow height line).

This is the case, if component height (overall

height) and nozzle height have been defined cor-

rectly.

Step 5: SIPLACE Vision

► If necessary, change the traverse path to modify

the vertical resolution.

► Under Stereo: Contour lines the measured height

lines are displayed in the 2D images.

This allows you to verify that exactly the THT pin

tips have been detected at the focal plane.

4.1.2.3 Tips and Tricks

Minimum THT pin length

With camera type 33, the minimum length for THT pins is 0.36 mm. If the THT pins are a bit

shorter, you may try one of the following two actions. In both cases you must check that the THT

pin tips are still detected exactly.

► Set the nominal length to 3.6 mm in SIPLACE Pro and increase the tolerance.

► Enable the Suppress checking of threshold values option in SIPLACE Vision.

Traverse path

With camera type 33, the default setting for the traverse path = 18 mm.

With this setting, the vertical resolution is high and the left and right images are usually very similar.

However, due to background reflections around the THT pin tips etc., there may be noticeable "dis-

similarities" between the left and right stereo images. In this case, a shorter traverse path can be

selected (e.g. 9 mm). Then the lighting differences between the stereo images are not as large and

the THT pins are detected robustly.

However, the height resolution is then lower.

4.1.3 Customer-specific Pattern Features

Odd shape components do not always have a shape or other structures, such as leads, which can

be used for identifying the component center and its orientation.

Examples

Component with board locks Specially shaped leads Component with curved shape,

e.g. lenses

The Pattern Feature lead group type allows the user to describe arbitrary abstract patterns on a

component. These patterns can only be created and changed in the SIPLACE Vision Editor during

teaching at the station. This type of lead group can be renamed or deleted but not created, edited

or copied in SIPLACE Pro.

The camera captures an image of the component and the user can now simply draw a frame

around single features or attributes and mark them for the Vision system. A special algorithm will

then extract a model out of the marked areas which can be used to later measure and align all

components of the same type. Structures that are not needed can be deleted easily.

4.1.3.1 Procedure

The following overview lists the single work steps that have to be performed in the specified order

to describe pattern features.

4.1.3.2 Application Example

Step 1: SIPLACE Pro

► In the Station Editor under Placement Station,

enable the OSC Package option under Installed

options.

Step 2: SIPLACE Vision

► In the Component Shape Wizard, select the Non-

standard or Connectors component shape type.

► Click on Other features – Pattern.

► Select the area to be taught in the image.

Step 3: SIPLACE Vision

► Click on Remove pattern.

► Zoom in the image extract and select unneces-

sary points in the image that are to be deleted.
