7.3.2 Teaching of the User Defined Template

The basic operation for teaching the template is explained as follows:

1. Move the cursor to the mark position whose data is to be taught.

Note that the X and Y coordinates of the mark must be entered before teaching

the recognition mark.

Figure 7.3.2.1

2 Press the CAMERA key of the HOD to start teaching operation with a camera.

The camera moves to the XY-coordinates of the mark at this point, and the

selected mark appears on the monitor screen. If no mark appears on the

monitor screen, check to see if the entered coordinates are correct.

If you do not select a camera as a teaching device, an error sound beeps, and

the machine cannot perform teaching recognition.

3. Use the +Y and/or –Y key of the HOD to select which direction the recognized

image data is to be rotated: positive or negative. After selecting the rotating

direction, press the ENTER key.

Note: The machine detects a white part as a mark. Whether the mark is

recognized as white or black with respect to the board color depends on

the contrast between the mark and the board, and on the light level for

the camera’s field of view. Normally, the mark is recognized as white. If,

however, there are lands, patterns, or silk printings around the field of

view of camera, the mark may be recognized as black with respect to the

board color. In this case, normal correction is impossible. Reverse the

black and white by pressing the +Y or -Y key on the HOD so that the

mark appears as white. If a mark is recognized as black against the

board, press the +Y or -Y key to reverse the black and white so that the

mark can be recognized as white.

4. Adjust the scale frame.

Set the top, left, bottom and right sides of the scale frame with the direction key

(+Y, -Y, +X and/or –X) to adjust the size of the scale frame

The FAST key changes the moving distance of the scale frame.

The camera picture and a rectangle frame appear.

Set the top and left scale frames first. Adjust them

so that they match with the top and left of the mark.

When adjustment is complete, press the ENTER

key.

In the same manner as above, set the bottom and

right scale frames.

When adjustment is complete, press the ENTER

key.

5. Adjust the noise cut level.

Use the +Y and/or –Y key of the HOD to adjust the noise cut level around a mark

so that the mark can be viewed clearly, and the noise around the mark can be

reduced as much as possible. After adjusting the noise cut level, press the

ENTER key to confirm it.

6. Select “PR” as a mark on the mark selection screen.

Use the +Y or –Y key of the HOD to select “PR”, and press the ENTER key to

confirm it.

Note: Only when you select a board mark, you can select “PR”. When you

select an IC mark, the machine automatically skips “PR”, and you cannot

select it.

7. Adjust the center of the template.

Move the crosshair cursor within the scale frame to adjust the center of the

template.

Use the direction key (+Y, -Y, +X and/or –X) to move the cursor. After adjusting

the center, press the ENTER key to confirm the center position.

Note: If you select a mark other than PR, the machine will not set the center of

the template.

8. Adjust the mark detection range.

Use the direction key (+Y, -Y, +X and/or –X) to adjust the scale frame.

After adjusting the scale frame, press the ENTER key to confirm it.

Note: To readjust the scale frame, press the VAC ON/OFF key of the HOD to

display the previous setting screen.

You have finished recognition teaching of the user-defined template here.

After recognition teaching, “(*)” appears next to the mark data, and it indicates

that the mark data is taught already. Perform recognition teaching for all of the

marks to be used.

When you press the CANCEL key of the HOD while the machine is teaching, it

finishes the current teaching operation. (Note that data you have entered so far

becomes invalid.)

Even though you press the CANCEL key, any device will not move.
