local

Select one of the following options to determine whether or not the

ﬁducial mark on each component placement point should be recognized.

Disable :

The local recognition function is not used.

Enable :

The local recognition function is used.

Note

(a) When "Enable" is set in the text box, the deviation of each component

placement point can be corrected.

(b) A component placement point and each recognition mode can be

speciﬁed in "(D02_09) V" of the placement data (P-data) and the

coordinates and mark code of a ﬁducial mark can be designated in

(D02_12), (D02_13), and (D02_14) of the placement data (P-data).

1-Point Recognition :

Put a ﬁducial mark on the center of component

placement point or a desired point around the

center.

2-Point Recognition :

Put two points (ﬁducial marks) symmetrically

on both sides of the center of the placement

position. (A-A', B-B')

Fiducial mark

When "1 Point", "2 Point", or "3 Point" is selected for the global PEC

recognition mode, the coordinates and mark code of each ﬁ ducial mark

must be entered in the corresponding text boxes.

Zones 1, 2, 3, 4, and 5

#1 X [mm] (Horizontal) and Y [mm] (Vertical)

Set the coordinates of the ﬁ rst ﬁ ducial mark in the text boxes.

#1 Mark Code

Set the mark code of the ﬁ rst ﬁ ducial mark in this text box.

#2 X [mm] (Horizontal) and Y [mm] (Vertical)

Set the coordinates of the second ﬁ ducial mark in the text boxes.

#2 Mark Code

Set the mark code of the second ﬁ ducial mark in the text box.

#3 X [mm] (Horizontal) and Y [mm] (Vertical)

Set the coordinates of the third ﬁ ducial mark in the text boxes.

#3 Mark Code

Set the mark code of the third ﬁ ducial mark in the text box.

Reference

Refer to "(A03) PEC Recognition Mark Data" for the mark codes.

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.

Reference

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.

(A02_06)

Sequence

Set one of the following options to specify the timing of PEC

recognition implementation.

It is recommended that "After Pick Up" should be set in normal cases.

Note

The components must meet the following requirements.

When "After Pick Up" is selected, a component is picked up and the

component recognition is performed on the component while the PCB is

being transferred to the PCB positioning section.

Since the component is already picked up, it can be placed soon after the

PEC recognition operation is performed, shortening the time to ﬁ nish a

PCB.

After Pick Up :

The PEC recognition operation is performed after a

component is picked up.

Before Pick Up :

The PEC recognition operation is performed before

a component is picked up.

This parameter should be selected when the PEC

recognition operation cannot be performed with a

component being picked up.
