Note 1 : The "?" in the program name is the relevant module number (1 ~ 6).

Note 2 : Camera type "I" represents an index nozzle type and "S" represents a single nozzle type.

The number preceding the I or S indicates the camera type.

Note 3 : For camera type 4I, 4S, 6I, 6S, 7I, and 7S use a back light nozzle but carry out front light

processing.

Note 4 : A size 60 fluorescent seal must be affixed to the back light nozzle used with camera

type 2S, 3S, 4S, and 7S. (A 47 square fluorescent seal can be used as a substitute.)

Note 5 : Since the part data and nozzle data for the 20.0 back light nozzle used with camera

type 4S and 7S is processed using a nozzle size of 15.0, set the nozzle type item in nozzle

data to "129" so that nozzle check will not be performed.

Note 6 : The fluorescent seal used with camera type 2S, 3S, 4S, and 7S is larger than the nozzle

changer and as a result nozzle change should never be carried out.

1) Camera Type 1I and 1S

a) Install a 1.3 size back light nozzle on the relevant module.

b) Set a QP1/QP2 95-001 board (prepared with double-sided tape) on the ICM conveyor.

c) Transmit the placement program SEIDO_C1_M?_I or S to the machine.

d) Set a feeder loaded with 3216 Pam chips in the specified slot and enable automatic operation

to place the 3216 PAM chips.

e) Use the DT-451 (651) to carry out automatic accuracy measurement and then check the

placement accuracy.

How to operate the DT-451 (651)

1) Set a QP1/QP2 95-001 board with 3216 PAM chip placement completed, in the board holder.

2) Click [F1] Origin on the computer operation display screen and wait for zero set to finish.

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.

0degrees

90degrees

270degrees

180degrees
