3.8.2.1 Description
The functionality of the 6-segment revolver head is similar to that of the 12-segment revolver
head. With its standard vision module, the 6-segment revolver head can quickly and accurately
place ICs with an edge length of up to 32 mm x 32 mm. It really comes into its own when there is
a very high proportion of ICs in the placement process. The cycle time of the 6-segment revolver
head depends on the dimensions and number of component leads or bumps.

3.9 Vision modules
3.9.1 Description
Each placement system has
– two component cameras on the placement heads and
– two PCB cameras on the underside of the X axis gantries.
The vision analysis unit is located in the control unit for the placement system. The component
vision module is used to determine:
– the precise position of the components at the nozzle and
– the geometry of the package form.
The PCB vision module uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB vision module also uses fiducials on the feeder modules to determine the exact pick-up
position of components. This is particularly important for small components.
