• Ball/Land

When you select “Ball” or “Land” in the “Type” field, these fields appear on the screen.

Select the shape of a ball or land. (However, the system does not distinguish the shape

currently.)

Specify whether to check the shape or not, and enter the judging

level.

− Diameter:

Specify whether to check the diameter. When checked, the

system checks each ball based on the average diameter of all

checked balls.

− Area: Specify whether to check the area.

− Ball exist?:

Specify whether to check that there is a ball or not. The initial

value “30 %” indicates that the system can detect the

condition: 20 % of a ball is cut away.

− Average diameter:

Specify whether to check the diameter with comparing the

average diameter of checked balls and the input diameter

• Outer Lead/Inner Lead

When you select “Outer Lead” or “Inner Lead” in the “Type” field, these fields appear on the

screen.

− Profile: Specify the lead type.

− Cut shape:

Specify the shape of the cut section if the tip of a lead is cut:

− Cut width, Cut length:

When you select “U-shape cut,” “Left bottom cut” or “Right

bottom cut,” enter these fields.

− Coating:

Specify the coating type of a lead. Not used at the present.

− Lead size:

For a gull-wing lead, enter the width and length of the tip of a lead that is in contact with a

board.

• Column

This screen appears when you select “Column” in the “Type” field. Not used currently.

◎ When the radio button “Point” is selected on the

“Element Group” dialog box, the menu items

shown in the right figure can be selected from

the “Type” list.

• Mark

When you select “Mark” in the “Type” field, this screen

appears.

- Matching:

Specify the tolerant range of the similarity.

The higher value you specify, the more strictly the

system judges the similarity.

(The initial value is set to “600.”)

• Side

For a component whose element is irregular-shaped (other than a circle or square),

you can cause the system to recognize a component with its side.

The bottom side is the reference side. When you

use the right side, enter “90°” in the “Theta” field of

the “Offset” menu item displayed on the “First

element position” column. In the same manner,

enter “180°” for the top side or “270°” for the left side.

• Corner

When you select “Corner” in the “Type” field, this screen appears.

- Radius:

Enter the radius of the corner section.

For a right-angled corner, enter “0.”

The reference corner is the bottom left corner when the

component supply angle is 0°.

If you want to use the bottom right corner, specify “90°”

in the “Theta” field of the “Offset” menu item displayed

on the “First element position” column. In the same

manner, enter “180°” for the top right corner or “270°”

for the left top corner.

• User definition

This column is displayed when “User definition” is selected as the “Type.”

• Allowable angle value:

Unless “Direction” is specified in the “Operation mode”

field, enter the allowable angle deviation generated

during recognition here. The entered value is applied in

both directions: positive and negative directions.

(“10 degrees” is entered as the initial value.)

The operation mode can be set when you create a

user-defined element, and you cannot change it on this

screen.

Reference side

Creating an extended array data format

When you select “Extended array data format” on the initial screen for creating a general-purpose

vision component, the following dialog box appears on the screen.

The procedure for creating data is basically the same as that for the “Element group/ Element

format.” However, for an “Extended array data format,” specify the X and Y coordinates of an

element one by one.

Specify an element in the “Location” field one by one. Enter the X and Y coordinates viewed

from the center of a component.

* Up to 256 locations can be set.
