Wide boards tend to deflect during placement such that, under certain circumstances, the compo-
nents can no longer be placed with the desired accuracy. Highly curved PCBs also affect the
placement accuracy. This problem can be easily rectified by fitting magnetic pin supports on the
lifting table.

Every Collect&Place head has a separate vacuum generator that supplies the holding and place-
ment circuit with the vacuum that it needs. The vacuum generator works on the Venturi principle.
The HF/3 machine's compressed air consumption is approximately 550 Nl/min, which means that
the compressed air supply must be dimensioned accordingly. If the owner does not have sufficient
capacity locally, the associated investment costs would be high, so we supply a vacuum pump that
will provide the necessary vacuum.
Other advantages of using the vacuum pump are:
– It roughly halves the machine's compressed air consumption.
– It reduces the input pressure.
– The placement machine can be easily integrated into existing lines.
– The ongoing operating costs reduce according to the energy costs.

The vacuum pump is maintenance-free and 100% oil-free. They have sufficient capacity to supply
the holding circuits of the Collect&Place heads.
