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.

– The rinse cycle is carried out via the rinsing station, in a rinsing tank provided for this pur-
pose (see Fig. 11.9 - 10
).
– The time can be set to between 0 and 600 minutes.
Number of rinse cycles: 11
– If you have set a time for automatic rinsing, then you can also set the number of rinse cy-
cles.
– This can be set to between 1 and 10 rinse cycles.
11
Automatic brushing after 11
– A time can be set for activating the brushing cycle, in order to clean the centering nozzle
and dispensing needle. During this cycle, the fluxer head moves over the rinsing tank to
which a brush is attached.
– A brushing cycle is carried out automatically when the machine is switched on, regardless
of the set brushing time.
– The brushing cycle is carried out via the rinsing station, in the rinsing tank provided.
(see Fig. 11.9 - 10
).
– The time can be set to between 0 and 120 minutes.
11
Number of brushing cycles 11
– If you have set a time for automatic brushing, then you can also set the number of brushing
cycles.
– This can be set to between 1 and 10 brushing cycles.

Flux application during the test run: (this function is only to be used by trained person-
nel) 11
– Flux dots can be applied to a PCB but not component placed in order to check the dots, and
find the optimum setting.
– Select the Processing off option from the Software options menu.
– Check the Apply flux during test run check box [X].
Flux dots will now be applied, but no components will be placed.
– The machine can also be run continuously without fluxing and without placing.
– Select the Processing off option from the Software options menu.
– Uncheck the Apply flux during test run check box [ ].
