The results of fiducial centering are indicated by a cross. The x and y offset values of the fiducial

center will be entered in the fiducial data field. 6

PLEASE NOTE 6

An incorrectly centered fiducial will cause a placement offset. 6

Å Press the Esc key to quit the option and return to the Test fiducial menu.

The dimensions of the pattern structure and search area are stored in the station computer. These

figures are required for calculating the travel path for the corners test. The centering offsets of any

fiducial centering which may already have been carried out will also be taken into account in cal-

culating the travel path. 6

Following this 6

– the test will be shown on the video display as it runs,

– the header will be shown with the option, the fiducial number and the quality factor, and

– in the footer the operator fields and command sequences will be shown and a test started

which determines the fiducial’s quality factor.

Å By pressing the Return key you can repeat the test procedure.

Å You can change the position of the gantry with the arrow keys. By entering the numbers 1 - 6

you can change the step width.

The PCB camera travels into the 4 corners of the search area, and each time, issues a measure-

ment command. For each measurement command, the machine controller is provided with the fi-

ducial quality by the vision analysis unit (MVS). The worst value (which is the worst case) of the

test is displayed on the screen in the header. 6

The quality value is a figure between 0 (= bad) and 100 (= very good) and should not fall below

the value 40 for the fiducial and the ink dot. If it does, we recommend you choose another fiducial.6

6.5.6.3 Move X/ Y Axes Option

When you select this option from the Test fiducial menu, the station computer will have the fol-

lowing actions carried out: 6

– The screen will close the Test fiducial menu and will switch over to the video image. At the

same time the current camera position will be displayed and the operator field option dropped

down.

– If there is the risk of a gantry/head crash, the axis controllers will be blocked.

Å After selecting the step width (by choosing a number between 1 and 6) you can use the arrow

keys to change the camera position of gantry 1.

NOTE 6

The default teaching gantry is always Gantry 1. You can, however, select Gantry 2 for this by

using the Select gantry option (see Section 6.5.3.1 on page 213). 6

Å With Esc you can quit the option. The Test fiducial menu will be displayed again.
