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.

3 Select the nozzle type to perform the test.
When the Measuring Nozzle Selection box appears, select the nozzle to
perform the 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 Press the emergency stop button, then seal the nozzle holes
tightly.
Seal the nozzle holes of all heads tightly with items such as carrier tape so
that air does not leak out.
5 When preparation is complete, cancel emergency stop.
Check safety, then release the emergency stop button and press the
[READY] button.
6 Press the [ENTER] key to start test.
The mount vacuum level is measured for about 8 to 20 seconds and the
results are then displayed.

3.4 Moving camera
The moving camera is installed in the head assembly and used to recognize
PCB fiducial marks or perform coordinate teaching. The focus, lighting
level and the scale of the moving camera must be adjusted correctly.
