1.2.4 P.E.C. Recognition

(1) P.E.C. Recog. Function

It can be selected whether or not the P.E.C. recognition function

should be used.

2PT. : The machine performs the tow-point recognition.

OFF : The machine does not perform the P.E.C. recognition.

One of the options ("OFF", "1PT.", "2PT.", and "3PT.")

can be selected. However, the machine perform the rec-

ognition only when "2PT." is selected.

(2) Center Recognition

It can be selected whether or not the machine should perform the

center recognition.

ON : The machine performs the center recognition.

OFF : The machine does not perform the center recognition.

When the center recognition function is used, a fiducial mark is

recognized once and the camera is moved to the position where

the recognized fiducial mark is located at the center of the visual

field. After that, the fiducial mark is re-recognized.

The positional accuracy is improved because the mark is recog-

nized at the center of the visual field (the spot of the lens with less

distortion).

(3) Fiducial Mark #1

X [horizontal] and Y [vertical]

Set the coordinates of the first fiducial mark.

Unit: mm

Code

Set the code No. of the first fiducial mark.

(4) Fiducial Mark #2

X [horizontal] and Y [vertical]

Set the coordinates of the second fiducial mark.

Unit: mm

Code

Set the code No. of the second fiducial mark.

(5) Recog. Adjust Correct

It can be selected whether or not the recognition adjustment point

(the center point to correct positional deviation between the P.C.B.

and the screen frame) should be specified to correct the align-

ment of the P.C.B. with the screen.

ON : The specified parameters in the "Recog. Adjust Point X"

and "Recog. Adjust Point Y" text boxes become the recog-

nition adjustment point.

OFF : The P.C.B. center is automatically specified as the recog-

nition adjustment point.

(6) Recog. Adjust Point X (horizontal) and Y (vertical)

Set coordinates as the recognition adjustment point to correct the

alignment of the P.C.B. with the screen.

Unit: mm

The specified parameters become valid only when "ON" is set in

the "Recog. Adjust Correct" text box.

1.2.5 Screen Recognition

(1) Scr. Recog. Function

It can be selected whether or not the screen recognition function

should be used.

2PT. : The machine performs the two-point recognition.

OFF : The machine does not perform the screen recognition.

One of the options ("OFF", "1PT.", "2PT.", and "3PT.") can be se-

lected. However, the machine perform the recognition only when

"2PT." is selected.

(2) Center Recognition

It can be selected whether or not the center recognition should be

performed.

ON : The machine performs the center recognition.

OFF : The machine does not perform the center recognition.

Mark Y is recognized once and the camera is moved to the posi-

tion where the recognized fiducial mark is located at the center of

the visual field. After that, the fiducial mark is re-recognized.

The positional accuracy is improved because the mark is recog-

nized at the center of the visual field (the spot of the lens with less

distortion).

(3) Fiducial Mark #1

X (horizontal) and Y (vertical)

Set the coordinates of the first fiducial mark.

Unit: mm

Code

Set the code No. of the first fiducial mark for screen recognition.

(4) Fiducial Mark #2

X (horizontal) and Y (vertical)

Set the coordinates of the second fiducial mark.

Unit: mm

Code

Set the code No. of the second fiducial mark for screen recogni-

tion.
