Use the following programming trick to avoid having to adjust the placement position:
When describing the body on the side of the short lead, shorten the length of the lead by the additional
length of the lead opposite. In the placement image printout, this gives the impression of a floating lead.
Alternatively, describe the body so that it includes the leads. SIPLACE Vision will not check this method
of programming.
To solve the problem and achieve satisfactory nozzle contact, you can also set a pickup offset in the CS.
These asymmetrical lead arrangements also apply to other CS types.
Joint datasets with ICOS data NOT possible: If ICOS descriptions do not include a heat sink (tab) lead
definition. There are some descriptions in which the body size is programmed incorrectly to simulate
pickup and placement symmetrical to the center point.
SW extensions: FaceDown recognition (See: New Siplace Vision Functions 702).can be programmed
and from SC 702.01 SW (SIPLACE Vision 4.1).

5.3.7.4 SOJ Component Shape (Small Outline J-Lead)
JEDEC description
Group description
Lead description
Special features
The component belongs to the SO class of components, although it is separately classified for the
illumination and filter settings.
Inspection of the lead number, position and pitch is set as a default for these leads and can not be
disabled.
We do not recommend selecting the COPLANARITY measurement option for this component
shape, since the hemispherical connection surfaces prevent reliable measurement results.
J-Leads should only be programmed when the component shape is really a J-Lead, otherwise
recognition errors could occur.
Joint datasets with ICOS data possible!
Body description: rectangular.
The Z height of the body determines the CO height for the
Z positioning profile.
The X/Y body dimensions determine the field of vision, the
Region of Interest.
The overall body outline is determined by the J-Lead leads.
This component shape has two (or more) lead groups on
the two component sides, meaning that the CO must be
asymmetrical to the body axes.
More than one group can be located on one CO side.
The leads in the groups must be identical, although their
numbers may differ!
The lead pitch and pitch tolerance must be identical in all
groups.
This component shape has so-called J–Leads, i.e.. leads
curved under the component body, in the form of a J.
These leads are defined by the lead length and width.
The leads are inside the body surface. Notches can not be
programmed.
The leads are aligned towards the body center line.

5.3.7.5 SOxx Component Shape (Small Outline xx)
JEDEC description
Group description
Lead description
Special features
SOxx with J-BEND type leads are classified as SOJ.
SOxx contain DIP, SSOP, SOP and TSOP.
Inspection of the lead number, position and pitch is set as a default for these leads and therefore can
not be disabled.
COPLANARITY measurement is possible provided the option has been installed.
Joint datasets with ICOS data possible –
SW extensions: FaceDown recognition (See: New Siplace Vision Functions 702).can be programmed
and from SC 702.01 SW (SIPLACE Vision 4.1).
(see MS-012 and MS-027)
Body description: rectangular.
The Z height of the body determines the CO height for the
Z positioning profile.
The X/Y body dimensions determine the field of vision, the
Region of Interest.
This also determines the inner starting edge of the Gullwing
leads.
This component shape has two (or more) lead groups on
two component sides, meaning that the CO must be
asymmetrical to one of the body axes.
The leads in the two groups must be identical!
The lead pitch and pitch tolerance must be identical in all
groups.
Different numbers of leads are permitted.
An offset between the two groups opposite one another is
also permitted.
This component shape has Gullwing leads i.e. the leads
protrude upwards from the IC level and point outwards in
the shape of a fan.
These leads are as wide as the solder resist contact
surface, on the board connection surface.
The lead length is significantly longer than the contact
length.
The leads are outside the body surface. Notches may not
be programmed.
