4.1.2.1 Procedure

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

to perform the stereo measurement when THT components are placed.

Performing Stereo Measurement

Step Action SIPLACE program

1) Enabling OSC package SIPLACE Pro

2) Setting component height (overall height and creep distance) –

Observing focus height

SIPLACE Pro

3) If a nozzle gripper is used, setting the nozzle height SIPLACE Pro

4) Enabling stereo measurement for THT pins SIPLACE Vision

5) If necessary, changing the traverse path in the stereo height

view

SIPLACE Vision

4.1.2.2 Application Example

Step 1: SIPLACE Pro

► In the Station Editor under Placement Station,

enable the OSC Package option under Installed

options.

In SIPLACE Pro the component height has to be set so that the THT pin tips are located in the

focal plane of the camera. In the focal plane, the THT pin tips are displayed most sharply, and the

measurement is most accurate. For this, the following settings are required:

Step 2: Setting overall height – SIPLACE Pro

Setting the component overall height (from the pin tips

to the component bottom).

► In the Component Shape Editor, set the compo-

nent overall height under Component Shape –

Form – Overall height (with pins).

Step 2: Setting creep distance – SIPLACE Pro

Setting creep distance = THT pin length

► In SIPLACE Pro Desk, set the creep distance =

THT pin length under Handling – Placement –

Creep Distance.

If you use a nozzle gripper, the nozzle height also has to be set.

Step 3: SIPLACE Pro

Setting parameters for the nozzle gripper

► In the Nozzle Editor, disable the Height check

height reference run under Custom Nozzle – Ad-

vancedData.

► Set the Nominal length from the nozzle bottom to

the component touchdown point under Nozzledi-

mensions.

Step 4: SIPLACE Vision

► Enable the Stereo Measurement option in the

Component shape wizard in the Meas. options.

► 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.
