Step 6: Station software
► Set the recommended acceleration values from
the teach function.
► Click on Start.
The test is automatically performed and the Execution test dialog displayed.
The results are displayed in the Results test dialog.
Step 7: Station software
► Check the results.
► Click on Upload acceleration values to program-
ming system.
The upload to SIPLACE Pro is not available until the recommended values have been tested.

4.2 New Features and Changes with R18-2
70 Bedienungsanleitung OSC Package User Guide OSC-Paket 11/2019
4.1.6 Increased Placement Force for Twin VHF Placement Head
An increased placement force up to 100 N is supported for the Twin VHF placement head.
Restrictions
●
The increased placement force to 100 N is only possible for the Twin VHF placement head,
item no [03096701-03]. Placements with a force greater than 70 N are not supported on sta-
tions with software versions < 710 and Twin VHF placement heads with a functional status <
[-03]. Such placements will be forced onto stations with station software version ≥ 710 by
SIPLACE Pro.
4.2 New Features and Changes with R18-2
In this chapter all features are listed that have either been newly introduced or have been updated
with R18‑2.
4.2.1 Placement of Snap-in Components – Improved Teaching
With R18-2, there has been an update for the placement of snap-in components introduced in
R16-2 (please refer to 4.1.1 "Placement of Snap-In Components" [}53]).
If the next board is already present in the input section, it will be moved in but not placed until the
settings for the first board have been confirmed.
In case of an error the stored data can be reset via Line Control GUI.
Restrictions
●
The improved teaching procedure for placement of snap-in components is not supported on
the SIPLACE CA4 / CA4 V2 placement machines.
4.2.2 Stereo Measurement for Gullwings and Pattern Features
With R18-2, there has been an update to the stereo measurement feature introduced in R16-2
(please refer to 4.1.2 "Stereo Measurement for THT Pins" [}57]).
From R18-2, the stereo measurement is also supported for the Gullwing and Pattern Features lead
group types. The same procedure is used for the measurement as for the stereo measurement of
THT pins.
NOTICE
Considering the height measuring range
Since Gullwings are often not in the same plane as the THT pin tips, the height measuring
range must be considered:
SST25: +1.94 mm to -3.9 mm around the calibration plane ("+" is in the direction of the
camera!)
SST33: +3.6 mm to -7.2 mm around the calibration plane.
► Follow the work steps that are described in section 4.1.2 "Stereo Measurement for THT
Pins" [}57].
► Please also refer to section 4.1.3 "Customer-specific Pattern Features" [}61].

4.2.3 Stereo Measurement – Measurement Parameter 4x Image Capture
With R18-2, there has been an update to the stereo measurement feature introduced in R16-2
(please refer to Stereo Measurement for THT Pins (from R16-2)).
From R18-2, the 4x image capture measurement parameter can be used in the stereo measure-
ment. At each position four images are taken, each offset in the X and Y directions by a half pixel to
each other. As a result, features which are smaller than the specified minimum size can be recog-
nized. The height measuring range is halved with the 4x image capture: with the SST 33, only the
height range from 1.8 mm to -3.6 mm is measured.
Example
4x image capture
Additionally, the traverse path can be shortened to reduce the lighting differences of the images.
Please also refer to section 4.1.2.3 "Tips and Tricks" [}60].
► Follow the work steps that are described in section 4.1.2 "Stereo Measurement for THT
Pins" [}57] with the following exceptions:
Step 4: SIPLACE Vision
► First, enable the stereo measurement as de-
scribed for the THT pins.
► Then activate the 4x image capture parameter
under Position.
