Pick Up Workflow
A - Rotate component into placement angle
B - Placement angle correction after optical
centering
1. Vacuum measurement pick up/ place
circuit
2. Vacuum measurement holding circuit
3. Optical centering (SIPLACE Vision)
If a component fails the optical centering (identify error), then this component remains on the
nozzle. After all other components have been placed the failed component will go to the reject
cycle.

Pick Up Workflow detailed
Pick up vacuum is by default always on.
Holding circuit of each segment is always on if vacuum pump or compressed air is on.

Automatic head offset correction (TX micron only)
●
The PCB camera centers the fiducial after
clamping to determine the exact position of
the board.
●
Max. 20 components will be picked up.
Components are then centered under the
component camera.
●
Automatic head offset correction:
– 25µm @ 3σ:
Every 60 min. 3 fiducial marks on the
Xfiducial bar are checked.
– 20µm @ 3σ:
Every 60 min. all fiducial marks on the
Xfiducial bar are checked.
– 15µm @ 3σ: Every 40 min. :
- The head offset is checked using the
calibration tool on the Xfiducial bar.
- All fiducial marks on the Xfiducial bar
are checked.
- All fiducial marks on the Yfiducial bar
on the vacuum tooling are checked.
– 25/20/15µm @ 3σ:
Every 5 min. the head offsets are
calculated using max. 20 components
of the current job which were picked up
this head cycle.
●
Place components on PCB according to
the program.
NOTICE
Calibration nozzles
For TX micron machines in every nozzle changer at least 1 calibration nozzle (4257) has to
be setup.
In both calibration pockets a calibration tool must be available.
This is necessary to ensure that the automatic head offset correction can take place.
