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

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 values>>

A total of eight 60-pin glass parts are placed as shown in the figure above.

The glass board and parts form a vernier scale (1 graduation is 0.005 mm).

Measure how many graduations the conforming location (location 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 degree’s value – 180degrees’ 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 input value sign table.

i) After the values are input, place the parts again in automatic operation (step 5), and carry

out measurement to obtain accuracy within the allowable tolerances.

j ) If the placement accuracy falls within the allowable tolerance ranges then input the data

into a QP242E Camera 6 Placement Accuracy Table (Excel file: QP242E camera6placement

accuracytable.xls) and obtain a printout of the table.
