5.3.7.6 PLCC Component Shape (Plastic Leaded Chip Carrier)
JEDEC description
Group description
Lead description
Special features
Inspection mode is set as a default for these leads and can not be disabled.
The illumination is set to J-Lead classification.
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 or, in the most common special
case, square.
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 four lead groups on the four
component sides, meaning that the CO must be
symmetrical to the body axes.
The leads in the groups must be identical!
The (pitch) and pitch tolerance must be identical in all
groups.
The number of leads in the groups may differ!
This component shape has so-called J–Leads, i.e..leads
curved in the shape of a J.
The leads are arranged on one level, parallel to the surface
covered by the component and are curved under the
component body, in the shape of a J.
The leads are as long as the contact length.
The leads are inside the body surface. Notches may not be
programmed. The leads are aligned towards the body
center.

5.3.7.7 QFP Component Shape (Quad Flat Pack)
JEDEC description
Group description
Lead description
Special features
Inspection of the lead number, position and pitch is set as a default for these leads and 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 or, in the most common special
case, square.
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 four lead groups on the four
component sides, meaning that the CO must be
symmetrical to the body axes.
The leads in the groups must be identical!
The lead pitch and pitch tolerance must be identical in all
groups.
Different numbers of leads are permitted.
Multiple lead groups are possible per side.
This component shape has so-called Gullwing leads i.e.
leads with level contact surfaces.
The leads are connected to the IC level and are then curved
down to the contact surface, standing away from the
component body in the form 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 contact length must be programmed shorter
than the lead length.
QFN (Quad Flatpack NO lead) are classified in the same
manner since the features (silver from black) comply with
the typical QFP arrangement.
The leads are outside the body surface. Notches may not
be programmed.

5.3.7.8 Socket Component Shape
JEDEC description
Group description
Lead description
All lead types are permitted for this component shape.
The leads are inside the body surface. Notches can not be programmed.
Socket with a 90° lead alignment (pointing outwards) could also be recognized as QFP.
Special features
Inspection of the lead number, position and pitch is currently not available and can therefore not be
enabled.
In many cases, the socket has leads which have half the width of the contact in the socket frame. In
this case, only the width of the socket frame (visible metal surface) is programmed.
Theoretically, a round Socket could also be programmed.
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).
Body description: rectangular.
The Z height of the body is the height in the CO center.
The X/Y body dimensions determine the field of vision, the
Region of Interest.

One or more groups are permitted.
The leads in the groups must be identical!
The (pitch) and pitch tolerance must be identical in all
groups.
Different numbers of leads are permitted.
The lead groups may be aligned inwards or outwards.
