Colinearity
In the case of colinearity (see camera image), the
straightness of a group with the same features is
searched for.
Do NOT mistake this type of inspection with the
coplanarity check, in which the gullwing lead
height deviations (for IVP 3D sensor also the ball
height deviation) to a calculated lead level are
determined.
This measurement function can be separately
enabled in the geometry program section
Special
Measurement
Options.
This checks the lead beginning of wraparounds on
component shapes and the lead end of gullwings
in inspection mode.
When using lead groups with three or more leads,
we check whether the lead measurement edges
are on a calculated straight line with +/- colinearity
length tolerance. This tolerance value can be
individually set for each group and is therefore
independent of the lead length tolerance value.
The lead feature position is compared to the
calculated component angle for two pins in a
group. This function is active for the following CS
types:
SOxx, QFP, SOT, DPACK, Socket,
Connector, Nonstandard

5.5.3 Rectangle
A new feature for "Nonstandard" CS types is the rectangle. The search looks for rectangles which are
either features or entire components (see the following diagrams).
The rectangle needs to be visible with the normal illumination for leads (a golden rectangular area on a
BGA does not fulfill this requirement). Rectangular shapes in 90° and squares in 45° can be programmed
and recognized.
The minimum and maximum size (NO multiple measurement at the stationary cameras) depends on the
camera resolution.

5.6 Coplanarity Measurement for Gullwing and Ball Leads
5.6.1 Coplanarity Measurement ILD2200
This coplanarity check determines the lead
height deviation for gullwings or, by using the IVP
3D coplan sensor, the ball height deviation to a
calculated lead level.
Do NOT mistake this inspection type with the
colinearity check, which determines the deviation
of the lead measurement edge to a calculated lead
straight line.
5-21: ILD2200 coplan sensor (laser class 2) of gullwings only
This coplan sensor (SST17) can be operated at
the station computers of the D1 / D3 / X2 or X3 in
combination with a TwinHead. Simultaneous
operation of the IVP 3D sensor at X machines in
not possible.
