2.1 The Need for Station 11 Proper Data Calibrations

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

each nozzle at Station 11.

Although it is possible to measure the nozzle centers of Station 6 with the parts camera, 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

checked by a mark camera. Each nozzle is rotated to 0 degrees, 90 degrees, 180 degrees

and 270 degrees and the vision processing data for the placed parts then undergoes

statistical processing to provide an accurate measurement of the mechanical error

amount.

2.2 Notes on Using PAM

In order to use PAM, the machine’s control card ROM must be replaced with the PAM

card ROM. Production operations are not possible while the PAM card ROM is installed

in the machine. To restore the machine’s production capabilities, the machine’s control

card ROM must be re-installed.

Moreover, the CP-6 PAM does not support the following commands and functions.

Commands

• Block skip

• Recovery

• Pass Mode

• Turnover Operation

• Nozzle skip

Functions

• Nozzle skip following a nozzle-centering alarm

• Statistical nozzle skip

• HELPS

2.3 Procedure Overview

Part Data and Nozzle Assignment Table

Prepare the part data and Nozzle Assignment Table for PAM.

1. 6 types of part data must be created.

The 6 types of part data are based on the standard 3216R part data, with only the

nozzle size being specified (input item: Nozzle_size_CP6).

• Part Data

Nozzle

No.1_3216 1.1 mm Data for part pick-up with the No.1 nozzle

No.2_3216 1.2 mm Data for part pick-up with the No.2 nozzle

No.3_3216 1.3 mm Data for part pick-up with the No.3 nozzle

No.4_3216 1.4 mm Data for part pick-up with the No.4 nozzle

No.5_3216 1.5 mm Data for part pick-up with the No.5 nozzle

No.6_3216 1.6 mm Data for part pick-up with the No.6 nozzle

2. Create the Nozzle Assignment Table as shown below.

• Nozzle Assignment Table

1 1.1 12 0.050 0

2 1.2 12 0.050 0

3 1.3 12 0.050 0

4 1.4 12 0.050 0

5 1.5 12 0.050 0

6 1.6 12 0.050 0

Notes: Regarding the input items at the part data and Nozzle Assignment Table

1. Although the 1.3 mm size nozzle is used for all the PAM nozzles (Nos.1 to 6),

different sizes (in 0.1 mm increments) must be entered as shown above in the “Part

Data” and “Nozzle Assignment Table” in order to differentiate between the 6 nozzles

(this prevents nozzle changes during PAM placement operations). By entering the

nozzle sizes in 0.1 mm increments, parts will only be picked up by the nozzle number

specified in the program.

Within the vision processing system for PAM, however, all the nozzle sizes are

processed as 1.3 mm.

2. If there are not enough 1.3 mm nozzles, perform measurement by placing all 20 1.3

mm nozzles on each head in order from No.1 to No.6 nozzle positions.

PAM Measurement

The PAM measurement occurs using the 20 No.1 nozzles at the 20 heads. If an accuracy

measurement fails, it is repeated until a result is obtained.

Note: The No.2 to No.6 nozzles are not used in the accuracy measurement.

No.2 to No.6 Nozzle Measurement

The No. 2 to No. 6 nozzle measurements are performed in the same manner as step 2.
