6.3.30 Placing component detailed: Z-axis downwards
Fig. 6.3 - 27 Placing component detailed: Z-axis downwards with light barrier mode
The placement force is defined by the spring in the sleeve ~2.4 N at 12 nozzle head
End signal X-, Y-, Star-axis:
– all 3 end signal available
– vacuum check before placement is executed (alternatively the component check in the
comp.sensor).
– component on the nozzle?
Z-axis starts:
– Z-axis positioning downward
LB above switches:
– solenoid air kiss ON
– enable LB bottom
LB bottom switches:
– End signal positioning downward;
– valve drive, pick up- placement position, to air kiss

6.3.31 Placing component detailed: Z-axis upwards
Fig. 6.3 - 28 Placing component detailed: Z-axis upwards
LB bottom switch:
– End signal positioning downward; valve drive, pick up- placement position, to air kiss;
– Measure air kiss pressure component placed
– Start term to move up
Z-axis started:
– Z-axis positioning upwards
LB above:
– reset solenoid for air kiss
– reset LB bottom signal
– enable start for gantry axes
Z-axis end signal (Z-axis on 0-position):
– (503) vacuum check after placement
– enable start for Star-axis

6.3.32 Placing component detailed: Z-axis downwards
Fig. 6.3 - 29 Placing component detailed: Z-axis downwards with current sensor mode
A placement force of 3 to 5 N at the C&P head.
End signal X-, Y-, Star-axis:
– all 3 end signal available
– vacuum check before placement is executed (alternatively the component check in the
comp. sensor).
– component on the nozzle?
Z-axis starts:
– Z-axis positioning downward
LB above switches:
– solenoid air kiss ON
– enable LB bottom
LB bottom switches:
– valve drive, pick up- placement position, to air kiss
current sensor on servo amplifier trigger:
– End signal positioning downward;
6.3.32.1 Advantage of placement with increased placement force
This "increased placement force" at placement offer you (on all stations):
– a good contact to the solder paste for large components / large contact surfaces to the PCB.
– A delay of ~20 ms compared to the standard placement cycle.
