1-Point Recognition

Only the X and Y elements are corrected. The θ element

(expansion, etc.) is not corrected.

Fig. 3B30

2-Point Recognition

Specify fiducial mark positions so that one fiducial mark is

kept as diagonally away from the other as possible.

Fig. 3B31

Avoid fiducial mark positions aligned horizontally or

vertically with each other as shown below.

Fig. 3B32

3-Point Recognition

Specify fiducial mark positions so that the triangle are formed

by connecting the three points (three fiducial marks) be-

comes as large as possible.

Fig. 3B33

When any two of the three fiducial marks are desig-

nated to be positioned as close as possible to each

other, the results of the correction will be almost the

same as "2-Point Recognition".

2.3 Operation Data

P.E.C. recognition mode Image

When "Enable" is set in "P.E.C. recognition function", set

one of the following options as an image recognition mode.

Disable : The image recognition function is not used.

Enable : The image recognition function is used.

Fig. 3B35

When the global recognition function is used together

with the image recognition function, both recogniz-

ing actions take place but the placement coordinates

are corrected according to the result of the image

recognition.

P.E.C. recognition mode 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.

When "Enable" is selected, set the coordinates of

the fiducial marks in (C02_13), (C02_14), and

(C02_15).

1 Point: Put a fiducial mark on the center of component

placement point or a desired point around the cen-

ter.

Fig. 3B37

2 Point: It is recommended that two points (fiducial marks)

should be located symmetrically on both sides of

the center of the placement position.

Fig. 3B38

(a) When "Enable" is set in the text box, the devia-

tion of each component placement point can

be corrected.

(b) The coordinates and mark code of a fiducial

mark are designated in the placement data (P).
