5.2.3.3 Standard Placement Workflow
Standard Placement
In this mode (light barrier down) the placement force at the CP20P Head is around 2N.
During the production, a nozzle scanning run is performed after 350 head cycles (can be set by
SIPLACE service if required) and after the completion of the board currently processed.
The nozzle quality check can be configured in four different levels via the station interface.
Pick Up Procedure
With early vacuum move to pick up position the vacuum generator switches the vacuum on before
the Z Axis moves down.
"Contactless": The first component is picked up with standard mode to determine the Z Axis down
position, the picked component is rejected. The next components are picked up with the absolute
position of Z Axis down.

Placement Procedure
"High force": Placement force depends on current of Z Axis, to determine end signal of Z Axis down
and vacuum generator switch to air blast.
Reject Procedure
"Defective" or "missing" is determined by:
●
Optical centering
●
Component sensor
Temperature Compensation
The temperature sensor is regularly checked and offset value will be calculated and will be used to
increase placement accuracy.
