[6-25] Pickup_Height_IPD_Z0
* If measuring with a dial gauge, be sure that the gauge is calibrated.
* Measure all MFUs at module 1, then use the MFU where the measured result was closest to
the average value to measure all modules. This measurement should also be performed at
modules with MTUs.
1) Mount a 10mm adjusting nozzle in the holder.
2) Place a device jig at the MFU’s number 1 position (left end).
3) Lower the Z-axis until the bottom of the nozzle makes contact with the surface of the device
jig which was mounted at the previous step. At this position, set a dial gauge on top of the
nozzle disk.
4) Slowly lower the Z-axis to find the point where the dial gauge begins to move.
5) The point where the dial gauge begins to move is the Z0 position. Execute the following
command sequence to automatically enter this data (Pickup_Height_IPZ0): [DEVICE] à
[ORG.POS.Z] à [SET].
6) Place the device jig at the MFU’s number 21 position (right end), then repeat steps 3 and 4
above to verify the Z0 position.
7) Verify that the positional difference between the MFU’s number 1 and number 21 (number 31
at 800mm module) positions is 46 pulses or less.
* The Proper data value is the average value for all MFUs (numbers 1 and 21, or numbers 1
and 31).

[6-26] Mark Camera Repeat Reading Accuracy
1) Transmit the program used for the placing accuracy measurement (see chapter 9) to the
machine.
2) Adjust the conveyor width to accommodate a PCB which is appropriate for the program, then
place the PCB at the IN conveyor.
3) In the step operation mode, specify sequence number 1, then press the START button to load
the PCB.
4) After the PCB is clamped, mark reading begins with the head positioned at the specified
coordinates. When mark reading is completed, the mark’s deviation amount displays at the
monitor and the START button is enabled.
5) Record the first reading result.
6) Specify the number 1 sequence again and record the displayed reading result.
7) Repeat this procedure 5 times for the same sequence.
8) Take the difference between the maximum and minimum recorded reading results and
calculate the X and Y direction deviations. Tolerance: 10 (0.01mm) or less
9) After performing an idling operation for 30 hours, repeat steps 1 through 8 above.
* Use only PCBs with good-condition marks when performing the above measurements.
[6-27]
After completing all the required procedures (described above) at all the modules,
proceed to the next chapter.
