3.3 Pickup/mount vacuum levels
3.3.1 Pickup vacuum level
When a nozzle descends and picks up a component, no air is allowed to
enter the nozzle so the vacuum pressure sensor detects a higher negative
pressure. When this detected level becomes higher than the preset pickup
vacuum level, the machine determines that the nozzle has picked up a
component. (There are other parameters the machine uses to check compo-
nent pickup.)
The pickup vacuum level should be preset for each head or nozzle, for a
level slightly higher (offset value: 5) than the minimum vacuum level
maintained when the nozzle is open (no component at the nozzle).
When measuring the vacuum level by selecting “All Nozzle Common” (see
step 1), attach Type 72 nozzles to all heads in advance.
1 Run the Vacuum Level command.
1. Select <3/3/B1 ADJUST TARGET> − ”Vacuum Level” and press the
[ENTER] key.
2. Select “Each Nozzle” or “All Nozzle Common” and press the [ENTER]
key.
3. Select A table” (or “B table”) − “ALL” − ”Pick” and press the [ENTER]
key.

3 Select the nozzle type to perform test.
When the Measuring Nozzle Selection box appears, select the nozzle to
perform vacuum level test and press the [ENTER] key. (The Measuring
Nozzle Selection box does not appear when “All Nozzle Common” was
selected in step 1.)
4 Change the nozzles by following the instructions that
appear on the operation monitor.
When changing the nozzles manually, always press the emergency stop
button.
5 Cancel emergency stop and press the [ENTER] key to start
test.
Pickup vacuum level is measured for about 8 to 20 seconds, and the
results are then displayed.

3.3.2 Mount vacuum level
When a nozzle descends to mount a component on the PCB, the vacuum
pressure at the nozzle is instantaneously inverted to a positive pressure, so
the vacuum sensor detects a lower value. When this detected level becomes
lower than the preset mount vacuum level, the machine determines that the
component has separated from the nozzle and is now mounted on the PCB.
The mount vacuum level should be preset for each head, at a level slightly
lower (offset value: 5) than the maximum vacuum level maintained when
the nozzle opening is sealed.
When measuring the vacuum level by selecting “All Nozzle Common” (see
step 1), attach Type 72 nozzles to all heads in advance.
1 Run the Vacuum Level command.
1. Select <3/3/B1 ADJUST TARGET> − ”Vacuum Level” and press the
[ENTER] key.
2. Select “Each Nozzle” or “All Nozzle Common” and press the [ENTER]
key.
3. Select A table” (or “B table”) − “ALL” − ”Mount” and press the [ENTER]
key.
