Each placement system has 

– four component vision cameras on the placement heads and

– four PCB vision cameras on the underside of the x axis gantries.



The vision evaluation units are located in the control unit for the placement system and the

component vision system is used to determine: 

– the precise position of the components at the nozzle and

– the geometry of the package form.



The PCB vision system uses fiducials on the PCBs to determine: 

– the position of the PCB,

– its rotation angle

– and the PCB delay.



The PCB vision system also uses fiducials on the feeder modules to determine the exact pick-

up position of components, which is particularly important for small components. 
