Checkpoint 3: PICK & MOUNT INFO. parameters
Open the PICK & MOUNT INFO. sub-window in the component
information and adjust the following parameters.
• Mount Timer
Set to a value larger than the current setting.
• Mount Speed
Set to a value smaller than the current setting.
Checkpoint 4: Reference pickup/mount vacuum pressures
Referring to ”3.7 Executing the Adjust Assistant commands” in this
chapter, check and adjust the settings for reference pickup and mount
vacuum pressures.
Checkpoint 5: Nozzle
If mount errors still occur even after checking all the above points and
making necessary corrections, the nozzle may have problems. Check the
following points.
Check to see if the nozzle tip is worn or nicked.
Try using another nozzle type by changing the Required Nozzle setting
on the BASIC INFO. sub-window in the component information.

10.4 Correcting the data after mounting
test
This section explains countermeasures you should take when mounting
position errors are found in the mounting test.
1. Mounting position errors at a specific point
When mounting position errors occur at a specific point on the PCB, the
component mount coordinate data is probably incorrect. Correct the data
as follows.
Mounting position error at a specific point

Mounting position error
1 Open the Mount Info. screen in the <1/2/PRD.DATA>
mode.
2 Perform trace to the mounting position.
1. Move the cursor to the “X” or “Y” column of the data line whose
mounting position deviates.
2. Set the trace/teaching conditions and perform trace.
Press the [F9] key (or select the <1/2/B0 TEACH, TRACE CONDITION>
command), then select “A table” (or B table), “Camera” for the teaching
unit, a slow speed, and a fiducial correction setting as necessary.
Then, press the [F9] key again to perform trace. The moving camera
moves to above the mounting position. The cross cursor displayed on
the vision monitor indicates the current mounting position.
Reference
For details on the trace and teaching functions, refer to “12. Teaching and trace” in this
chapter.
3 Check the data.
If the cross cursor shifts from the center of the land patterns as shown in B,
you must correct the mount data by teaching. (You do not need to correct
the data when the cross cursor is at the center as shown in A.)

4 Perform teaching to correct the mounting position.
1. Manipulate the YPU joystick so that the cross cursor is aligned with the
center of the land patterns.
2. Press the [F10] key twice to enter the correct coordinates of the center
of the land patterns.
2. Particular component shift from the mounting positions
When a particular component shifts from its mounting position, the
component may not be recognized correctly. Open the Component Info.
screen in the <1/2/PRD.DATA> mode and run the Adjust Assistant for
the data you want to check.
Refer to “3. Creating the component information” for details on the
Adjust Assistant.
3. Mounting position shift on the entire PCB or in a particular
block
When the mounting position for the entire PCB shifts, the “PCB Origin”
settings in the PCB Info. are probably incorrect (A in the figure below).
When the mounting position for a particular block shifts, the coordinate
settings in the Blk Repeat Info. are probably incorrect (B in the figure
below).
