7.7 Mark Camera Adjustments

7.7.1 Focus Adjustment

Note that before adjusting the mark camera the X0Y0 and the Z0 adjustments must already be

completed, and the proper data input into the machine.

1. Clamp the fiducial jig plate in the main conveyor clamper. Make sure that the two tooling pins fit

smoothly into the two holes in the jig plate. (figure 16)

2. Move the fiducial jig plate under the mark camera by inching. Set the height of the main table to Z0

as follows:

[SET] → [PROPER] → [CAMERA] → [XC/YC] → [Z0] → START

NOTE: Z0 must be calibrated before carrying out this adjustment. When focusing the mark camera,

make sure the table is set at Z0.

3. Loosen the two height positioning bolts and adjust the focus by raising or lowering the height of the

camera. (see figure 17)

4. The focus is set when the black circle and silver dot in the center of the mark camera jig are in

clear, sharp focus.

7.7.2 Mark Camera Resolution, Skew, and XC YC Calibration

1. Set the table height to Z0. Clamp the XcYc jig using pins at Z0.

2. Press SET à PROPER à ID code à CAMERA à XC/YC.

3. Jog to align the mark on the XcYc jig with the crosshairs on the monitor (fig.18) then press SET.

4. Press RETURN à Mark à START. The resolution and delta will be measured for the mark

camera.

5. Rotate the camera bracket (fig.19) in order to set Delta Q to 0. Then repeat from step 2 again.

(Tolerance ----- less than ±0.05 deg.

Mark camera resolution ----- 18.2 to 19.3 um/pixel

Mark Read Pos Xc should be in the following range:

Mark Read Pos Xc – 45100 to – 45300 (L à R flow) , – 400 to – 600 (RàL flow)

Note! If the PCB was reverse flow, R? L, (reference pin position = left), add 10000 pulses to XC.

6. If outside the prescribed range, loosen the focus adjustment bolts and adjust the height of the

camera. Re-measure the resolution and repeat until the values fall within range.

PAM (Placing Accuracy Measurement) is a function for measuring the part placing accuracy.

When PAM is started, a correction value for the station 11 (part placing station) proper data is

calculated, and the ST11 proper data is re-entered and saved in accordance with this correction value.

This data is also transmitted back to the host computer (FujiCam, F4G, MCS).

The ST11 proper data acts to correct mechanical positional errors (due to working and mounting error

amounts), resulting in a uniform correction. X and Y direction correction values are entered for each

nozzle. As the system consists of 20 heads with 6 nozzles per head, this results in a total of 240

proper data input items.

Corrections in Station 11 Proper data are required to counter the mechanical deviation of each nozzle

at station 11.

Although the nozzle centers are measured at station 6, (parts cameras) it is impossible to measure the

centers at station 11. The placement position of parts will be inaccurate without compensating for

these mechanical deviations because, it is impossible for each nozzle to stop at the exact same point.

As shown in this illustration, when a nozzle cannot move in a completely vertical direction due to

mechanical errors, the center of a part, as seen by the vision processing system, and the actual center

may not correlate.

The measurement performed by PAM involves a process in which dummy chips are actually placed on

a mark reference board, with the chip placement accuracy being measured by the mark camera. Each

nozzle is rotated to 0, 90, 180 and 270 degrees. The vision processing data for the placed parts then

undergoes statistical processing to provide an accurate measurement of the mechanical error amount.

Note: the following procedure lists the steps needed to perform PAM at the machine. For further details

on PAM and menu displays, please refer to the CP-6 PAM Operation Manual available on the Fuji

web-site.
