3) Click [F2] Auto, select "qp2_indx.pgo" from the placement file selection screen, and then
click [OK].
4) Press START once it begins flashing to start automatic measurement.
5) When automatic measurement finishes and the automatic measurement completion
screen displays, click [F1].
6) Enter a file name of eight characters or less and save the measurement data.
7) Double-click [Program Manager], [Accessory], and [Note Pad].
8) Open the relevant note pad file and then select [File] and [Print] to print the file.
f) Camera type 1I and 1S placement accuracy
Check whether the accuracy follows the specification.
Placement accuracy (3 sigma) à ± 0.1mm
Once the accuracy check is completed transmit the Proper data to F4G and then save the
data.
g) If the placement accuracy results exceed the allowable tolerance ranges then carry out
calibration (Center_Offset, Final_Offset).
Center_Offset is the compensation value for offsetting the nozzle center of rotation to zero.
Final_Offset is the compensation value for offsetting the average value of all placement
parts to zero.
h) Add the Center_Offset X and Y and Final_Offset X and Y values to the original value and
then directly enter the values at the machine using the following command operation.
[PROPER], [CAMERA], [ETC], [ETC], select [Center_Offset] or [Final_Offset] for input, use
the arrow keys to select X or Y, input the value and then hit return.
  
 <<How to obtain the input value>>
As shown in the figure to the right, a total of 32 parts (3216 PAM chips) are placed.
Center_Offset X and Y are obtained using the following equation.
(0 degree’s average value – 180 degrees average value) ÷ 2
Final_Offset X and Y are obtained from the average value of all placed parts.
Obtain the sign of the input offset values for Center_Offset X and Y and Final_Offset X and Y from
the following table.

i) After the values are input, place the parts again from automatic operation (step 5),
and carry out measurement to obtain a level of accuracy within the allowable tolerances.
 2) Camera type 2I, 2S, 3I, 3S, 4I, 4S, 7I, and 7S
a) Install the respective back light nozzles on the relevant module.
b) Set each glass board (prepared with double-sided tape) on the ICM conveyor.
c) Transmit each placement program to the machine.
d) In the case of an MFU set the glass part-receiving jig in the specified slot. For an MTU set
the glass parts tray in the specified slot (tray holder). Then enter automatic operation and
place the glass parts.
e) Use the DT-451 (651) to carry out automatic accuracy measurement and then check the
placement accuracy.
1) Select the following file from the placement file selection screen.
Camera type 2 : seido_c2.pgo Camera type 3: seido_c3.pgo
Camera type 4, 7 : seido_c4.pgo
f) Camera type 2I, 2S, 3I, 3S, 4I, 4S, 7I, and 7S placement accuracy
Check whether the accuracy follows the specification. (3sigma)
* For glass parts à ± 0.1mm
* For 4 direction reed parts à ± 0.04mm
Once the accuracy check is completed transmit the Proper data to F4G and then save the
data.
g) If the placement accuracy results exceed the allowable tolerance ranges then carry out
calibration (Center_Offset, Final_Offset).
h) Add the Center_Offset X and Y and Final_Offset X and Y values to the original value and
then directly enter the values at the machine using the following command
operation.[PROPER], [CAMERA], [ETC], [ETC], select [Center_Offset] or [Final_Offset] for
input, use the arrow keys to select X or Y, input the value and then hit return.

<<How to obtain the input value>>
  A total of four glass parts are placed as shown in the figure.
 * The glass board and parts form a vernier scale (1 graduation is 0.00 25 mm) and it
is possible to measure how many graduations the conforming location (position where
the 4 leaded sides of a part match the pattern) deviates from the pattern center.
Center_Offset X and Y are obtained by (0? value - 180? value) / 2.
Final_Offset X and Y are obtained from the average value of all placed parts.
The sign of the input values for Center_Offset X and Y as well as Final_Offset X and
Y are obtained from the previous table.
i) After the values are input, place the parts again in automatic operation (step 5), and carry
out measurement to obtain a level of accuracy within the allowable tolerances.
 3) Camera type 6I and 6S
a) Install the respective back light nozzles on the relevant module.
b) Set each glass board (prepared with double-sided tape) on the ICM conveyor.
c) Transmit each placement program to the machine.
d) In the case of an MFU set the glass part receiving jig in the specified slot. For an MTU set
the glass parts tray in the specified slot (tray holder). Then enter automatic operation and
place the glass parts.
e) Use the magnifying glass with attached monitor to measure the accuracy and then check the
placement accuracy.
f) Camera type 6I and 6S placement accuracy (Flip chip Module)
Verification of the placement accuracy is complete if the results fall with in the following
specification.
Placement Accuracy (3 sigma): ± 0.03mm
Once the accuracy check is completed transmit the Proper data to F4G and then save the
