1.2 Operation Data

(4) Vacuum Rel. Wait Time

Set the waiting time during which the picked P.C.B. is released

and the backup table descends.

Unit : seconds

(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

current 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

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

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

tioned 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

Only "2-Point Recognition" is performed.

(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

recognized 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

Recog. Mode

Select the recognition mode.

Mark :

This recognition mode uses fiducial marks.

Model :

The image taken with the recognition camera is regis-

tered as "Model".

This mode uses the "Model" in place of fiducial marks.

Model + Mark :

This mode recognizes the image in the center of the

model as in the mark mode, after rough positioning with

the model mode.

Code

Set the code No. of the first fiducial mark.

Auto Gain Adj.

Select whether or not the automatic gain is adjusted when the

PEC recognition is tested.

ON : The automatic gain adjustment is performed.

OFF : No automatic gain adjustment is performed.

Gain, Level

This sets the amplification rate, when the signal of the image

(taken by the PCB recognition camera) is converted to image

data showing brightness.

• When the gain is decreased, the contrast becomes

greater.

• When the level is decreased, all of the brightness be-

comes greater.

Calib. Lamp

Normal : Selected when the contrast between fiducial mark

and PCB surface is adequate.

Ring : Selected when the gold-plated mark is used for

fiducial marks.

Both : Selected when the silver-plated mark is used on the

ceramic PCB and there is slight contrast between

the colour of the PCB surface and the fiducial

marks.
