You should select this option when centering errors occur with standard lighting. The 4 possibilities available
here for selection enable you to match the lighting optimally to the component in question. Each of these
options contains certain combinations of the flat, middle and steep types of illumination.

5.11.1 Description of Functioning
The coplanarity laser module is used for measuring vertical bending in the connection leads of components.
The leads height is measured by a non-contact method working on the principle of laser triangulation.
The placement head picks up the component which is to be checked, centers it optically with the IC camera
and then moves each of its four sides in turn over the stationary laser beam of the coplanarity laser module.
Here each lead is scanned from the bottom up by the laser beam. The laser light scattered by the underside of
the leads is detected by a sensor and serves as a basis for calculating the exact position of the lead with
respect to the board. The positional values thus obtained are then compared with the limit value specified by
the user. If this value is exceeded, the component will be discarded or returned.

The coplanarity laser module is used in combination with optical component centering using the vision sys-
tem. Components with bent or missing leads will be detected and discarded as appropriate.
