3.3 Operation

(C02_04)

Window Size [mm]

Set the recognition area (complete square) for the PEC recognition function. Set preferably small

values to avoid false recognition and shorten recognition time.

Fiducial Mark

• Data Input Range: 1.0 to 10.0

(C02_05)

Mark Image

Select one of the following options as an image of the mark pattern to be captured by the camera.

Select either mode according to the difference in contrast between a mark pattern and its

surroundings to get a clear fiducial images.

Bright (Normal) : Bright Fiducial/Dark Background

Dark (Inverted) : Dark Fiducial/Bright Background

Wrong mode selection causes malfunction of the recognition.

3.3 Operation

(C02_06)

Mark Level

Set the threshold levels of the fiducial marks. In normal cases, set "High".

High

: Both identity and similarity between the shape of a fiducial mark and the real image are

detected on a high level.

Middle : Either identity or similarity between the shape of a fiducial mark and the real image are

detected on a middle level.

Low : Both identity and similarity between the shape of a fiducial mark and the real image are

detected on a low level.

(a)

Identity

: Degree of identity between the shapes of the speciﬁed mark and the real

image (including the size)

(b)

Similarity

: Degree of similarity between the shapes of the speciﬁed mark and the real

image

(C02_07)

Angle [deg]

Set the angle at which a fiducial mark should be turned clockwise.

• Data Input Range: 0°, 90°, 180°, 270°

(a) A numerical value must be entered in increments of 90°.

When a value other than the speciﬁed increments is entered, the "Information" window

appears, indicating that the entered value (angle) is changed to "0°", "90°", "180°" or

"270°".

(b) When "Thru Hole / Land" is selected in the "Mark Type" (C02_02) combo box, the color

of the angle cell is highlighted and "0 deg" is set in the "Angle [deg]" text box.

Coax, Ring, Option

The brightness level for each lighting is selected from the following items.

Off Std -80% -60% -40% -20%

+20% +40% +60% +80% Auto

PEC recognition Set

Common : When selected, the PEC recognition is performed with the common setting to the

both lines.

Individual : When selected, the PEC recognition is performed with different setting for each

machine.

(C03_02)

Beam

It can be determined which beam should be used for the global and image PEC recognition

operations.

Beam 1 : Select this when only Beam 1 should be used for PEC recognition operations.

Beam 2 : Select this when only Beam 2 should be used for PEC recognition operations.

Automatic (1 or 2)

: The machine determines which beam (Beam 1 or 2) is more suitable for PEC

recognition operations and selects the better one.

Both Beam : Select this when both beams (Beams 1 and 2) should be used for PEC recognition

operations.

As for the local PEC recognition, the PEC recognition operations are performed with the beam

by which components are placed regardless of this designation of the PEC recognition beams.
