9.4 Travel Profiles - Placement
9.4.1 Z-Axis Down
9.4.1.1 Standard Mode - Placement: Z-Axis Down
The placement force is roughly 2.4 N in this
operating mode, with light barrier down on the
C&P12.
End position signal for X/Y and star axes:
All 3 end position signals available
Perform vacuum test "before placement". This
determines whether the CO is at the nozzle.
Z-axis starts:
Positioning of Z-axis downwards
LB up switches:
Electromagnetic valve for air kiss ON
Release signal for function LB down
LB down switches:
End position signal for positioning Z-axis
down;
And valve adjusting drive pickup/placement
position ON for air kiss

9.4.1.2 Placing with Increased Placement Force: Z-Axis Down
Benefits of Operating Mode "Increased Placement Force"
With this "higher placement force" function, you can:
Reliably set large components and components with large contact surfaces into the soldering paste/
adhesive!
However, this option makes the placement procedure around 20 ms longer than the standard
placement procedure!
The placement force is 3 -5 N in this operating
mode, with current sensor.
End position signal for X/Y and star axes:
All 3 end position signals available
Perform vacuum test "before placement", to
determine whether the CO is at the nozzle.
Z-axis starts:

9.4.1.3 Placement: Z-Axis Upwards "Creep to Target Position"
Benefits of the Special Mode "Creep to Target Position"
The "slow approach to placement height" option allows you to:
FLIP-CHIP components with their ball-type leads can be dipped into the filler material on the board
without trapping any air!
However, this option makes the placement procedure around 20 ms longer than the standard
placement procedure!
In the case of LRU/LRL 503 and SIPLACE Pro,
this placement type can "only" be programmed in
the CS "for SR/MC 503 stations and higher".
End position signal for X/Y and star axes:
All 3 end position signals available
Perform vacuum test "before placement", to
determine whether the CO is at the nozzle.
Z-axis starts:
Positioning of Z-axis downwards, the selected
speed profile switches over to minimum speed
1 mm before reaching the placement height.
LB up switches:
Electromagnetic valve for air kiss ON
Release signal for function LB down
LB down switches:
End position signal for positioning Z-axis
down;
And valve adjusting drive pickup/placement
position ON for air kiss
