(5) PCB Clamp Offset

The backup table ascends to the position where a P.C.B. is chucked.

It starts ascending again after the P.C.B. horizontal clamping unit

has chucked the P.C.B.

When thin P.C.B.’s are used and chuck errors occur, enter a value

as timing with which a P.C.B. is chucked and the backup table

starts ascending again and a value that represents the position

where the P.C.B. horizontal clamping unit starts to chuck the P.C.B.

Timing [sec] : Enter a value that represents the timing

with which the backup starts ascending

again after it has stopped.

Unit: seconds

Position [mm] : Enter a value that represents the

changed dimension based on the cur-

rent position.

Unit: mm

When a minus (-) value is entered, the

height for chucking start can be changed.

Bef.Clamp Bkup Spd. : The ascending speed of the backup table

can be set in the range of 10 steps (Full

Speed to 90 Down) before the P.C.B.

is clamped.

Unit: %

Aft.Clamp Bkup Spd. : The ascending speed of the backup table

can be set in the range of 10 steps (Full

Speed to

90 Down) after the P.C.B. is clamped.

Unit: %

(6) P.C.B. Stopper Offset Y [mm]

Set the offset in the Y direction of the stopper that is used to stop

the P.C.B. in the table chute section.

Unit: mm

When the offset is "0" (zero), the P.C.B. stopper is located at the

center of the P.C.B. end plane.

Specify the offset when there is a cutout, etc., at the center of the

P.C.B. end plane.

(7) PCB Cut Offset [mm]

When the P.C.B. has a cutout at its edge and must be positioned

against the P.C.B. stopper, enter the depth of the cutout in the text

box.

Unit: mm

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.
