Waiting time for the PCB conveyor 11
– The time for which the PCB remains in the station until it undergoes further placement. This
ensures that the flux dries reliably, and the component cannot “float away”.
– This time is measured from the last flip-chip component to be placed,
– and can be set to between 0 and 40 seconds.
PLEASE NOTE
Setting this waiting time can have a detrimental effect on line utilization. 11

Automatic rinsing after: 11
– To prevent the centering nozzle and dispensing needle from crystallizing after a long break
between flux applications, a time can be set after which the rinse cycle starts. This means
that the preset rinse cycle is carried out immediately before the next flip-chip is placed, ac-
cording on the selected placement sequence.
– A rinse cycle is carried out automatically when the machine is switched on, regardless of
the set rinsing time.
