5.2.2.9 Pressure Control Valve (PRV)
1. Energy and data supply
2. Compressed air connection
3. Vacuum/air kiss for pickup/placement
circuit
4. Discharged air for cooling the X linear
motor
5. Mounting for pressure control valve
●
The PRV supplies the pickup/placement circuit with vacuum during the pickup process and
switches over to air kiss during placement.
●
The valve can be replaced during service work.
●
Sensitivity against dirt and dust is reduced.
NOTICE
The PRV introduced with the C&P20 P is not to be cleaned. Otherwise the built in
protection membrane can be damaged.
5.2.3 Placement Process
5.2.3.1 Placement Positions
1. Vacuum measurement holding circuit
2. Optical centering (component camera)
3. Position of component sensor
4. Vacuum measurement placement circuit
5. Pickup/ placement position and reject
position
6. Direction of processing in C&P mode
A - Rotate component into placement angle
B - Placement angle correction after optical
centering
1. Optical centering (SIPLACE Vision)
2. Vacuum measurement holding circuit
3. Vacuum measurement pickup/ place circuit

5.2.3.2 Placement Workflow
●
Use PCB camera to center 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.
●
Place components on PCB according to
the program.

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.
