Notes: The deviation in the placement position is corrected by correcting the Proper data. Attempts to perform a 100% correction will result in an over-correction, and will cause an even greater deviation (overshoot). Th…

6. Placing Dummy Parts

After initializing all heads, end the editor command mode, then use the placing

commands to place the parts.

1. Press [RETURN] to return to the initial screen.

2. Select [PAM] —> [PLACE].

3. Press the START button.

4. Press the START button again to begin part placement.

7. Dummy Parts Measurement

After the dummy parts have been placed, use the measurement command to measure

them with the board still on the XY-table. This procedure consists of measuring the

amount of deviation from the program coordinate values (nozzle center measurement

values).

1. Select [MEASUREMENT]

The XY-table begins to move, and the fiducial mark camera acquires images of the

actual positions where the parts have been placed. This is followed by statistical

processing.

2. Deviation display

i) Select the following commands:

[EDITOR] —> [NOZZLE TYPE] —> [SELECT NZL]

(select the number of the nozzle being measured)

ii) Check the Avg. dx, and dy values.

Note: A correction is required if the deviation exceeds 10 (0.1).

3. Proper data correction

The following is the correction procedure which must be performed at placing

heads where the deviation (Avg. dx, dy) exceeds 10.

i) When the Avg. dx, and dy values exceed 10, add half their value to the

Proper X, Y values.

Example:

Proper X

Proper Y

-7

Proper Y

-15

Avg.dx

Avg.dy

-16

Notes: The deviation in the placement position is corrected by correcting the Proper data.

Attempts to perform a 100% correction will result in an over-correction, and will cause

an even greater deviation (overshoot). Therefore, only 1/2 of the calculated value

should be added (never add the full value).

ii) If the deviation (Avg. dx, dy) is 10 or less,, repeat Step 6 “Placing Dummy

Parts” to the end of Step 7 “Dummy Parts Measurement” procedure shown

above.

8. Results Display

9. Sig. X, Y, Q (3-Sigma) Check

1. Select the [RESULTS] command.

2. The correction procedure is complete if all the sig. X, Y, Q values are 100 or less. If

any values exceed 100, repeat Step 6 “Placing Dummy Parts”, then check the sig.

X, Y, Q values again.

3. Select the [DATA SAVE] command.

Continue with the Proper data corrections for all the other nozzles.

10. Transmitting Proper Data From Machine to Host

Transmit (and back-up) the Proper data from the machine to the host (F4G or MCS).

This completes the ST11 Proper data adjustments using PAM.

Tolerance range

After the PAM measurement is completed, the following information can be output (to

the printer if connected) for all number 1 to 6 nozzles: deviation amount, deviation

average, max./min. deviation, accuracy result.

Fuji guarantees a CP-6 placing accuracy of ±0.1 mm. However, because machine

efficiency can vary due to maintenance and operating conditions, it is impossible to

group all machines into one tolerance range. Keep this in mind when deciding the best

placing accuracy for your specific machine in order to obtain better results from the

calibration process.

2.7 Placing Accuracy Verification

1. Use a mark reference board to adjust the ST11 Proper data.

2. With the Proper data set (step 1 above), perform the part placement and

measurement operations using a pin reference program. Verify that the accuracy

is acceptable.
