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.

M/C PAM Procedure

1. Prepare the Nozzle Assignment Table in the PGO so 1.30Ø nozzles are installed at holder position

3 and 0.70Ø nozzles are installed in position 1. (Actually, the configuration does not matter other

than to make sure the nozzle # 1 is included in the center test data.) The # 1 nozzle is used as the

reference for all other nozzle locations. (It is important for the # 1 nozzle to be measured.)

2. Set the bend limit for holders 1 and 3 to 0.05mm.

3. Carry out nozzle center measurement. Select: [SET] → [MANUAL] → [CENTER] and press Start.

Make sure nozzle # 1 is measured during centering as it is the reference for all other nozzles.

If any nozzles fail the center test, change the bad nozzle(s) and run center until all nozzles pass.

4. Receive the proper data to the host computer.

5. Edit the X / Y placing offset Proper data (at the host) so all values equal 0.

6. Replace the system Rom card with the PAM Rom card, then boot by Reset Start.

7. Transmit the proper, status and programs to the machine. After transmitting the data, turn the

power OFF and reboot.

8. Load the PAM board using the loader commands on the main menu. Clamp the PAM board using

two tooling pins. Ensure the board is properly seated on the pins.

9. Load the PAM components at slot # 1 on D1.

10. First, select the Narrow PAM program and press: [PAM] → [PLACE] → [START]

11. After placement is finished, leave the board on the XY table, select [MEASURE] and press Start.

12. The Avg. dX/ dY results will appear on the monitor as indicated in figure 1.

Note: If the Avg. dX/ dY results are greater than 10, re-calibrate X0/Y0 and Xc/Yc.

Note: The unit of measurement is 1/100mm for dX/ dY. The data entered in the proper placing offset is

in units of 1/100. The average deviation is rounded up to the nearest 1/100 from an initial

precision of 1/1000.

13. If the Avg. dX/dY results are less than 10, transfer the Avg. dX and Avg. dY results to Proper X and

Proper Y (see fig. 2) Press: INCHING F + INCHING 1 together and press F4 on the display twice

to transfer the Avg. dX/ dY figures to the Proper X/Y columns. (This is only done during this time)

14. Run the Narrow program again and check the results. (fig.3) If the values for Avg. dX/ dY are less

than 2, the procedure is complete. If not, proceed to step 15.
