Position and Function of the Individual Star Stations
Star station 1:
▪ Pickup cycle
The nozzle is lowered towards the component. After a vacuum has been produced with the help of
the valve positioning function, the nozzle takes the component from the feeder module.
▪ Placement cycle
The nozzle, together with the component, is lowered onto the PCB that has been moved into place.
The valve is positioned to cut off the supply of vacuum to the nozzle. A brief burst of air separates
the component from the nozzle and the component is placed onto the board.
Star station 3:
▪ Abwurfzyklus bei D4/D4i/D3/D2/D2i
(Bei D1/D1i wird in Sternstation 1 in den P&P-Abwurfbehälter abgeworfen)
The valve is positioned to cut off the supply of vacuum to the nozzle. Defective components are re-
jected from the nozzle with a short air blast of compressed air and are discarded.
Star station 7:
▪ The component is optically centered.

Star station 9:
▪ Pickup cycle
The nozzle is rotated into the "pickup" position.
▪ Placement cycle
The component is rotated into the correct placement angle with the help of the DP axis.
Between star station 11&12
▪ The "presence" and "height" of the component at the nozzle is checked by the component sensor
(optional).
