⑦

Cut shape

Specify the shape of a lead end.

All of the settings other than “Flat” are handled in the same manner. When you select a

setting other than “Flat”, set the “Cut width” and “Cut length” fields.

- In the example, the shape of a lead end is flat.

Select “Flat” from the “Cut shape” combo box.

⑧

Coating

This item is not to be used. Select “Bare” from this combo box.

⑨

Cut width

This item is not to be used. Enter “0” to this field.

⑩

Cut length

Set this item if you select a setting other than “Flat” from the “Cut shape” combo box.

Enter the length of a not-flat portion measured from the lead end.

- In the example, the shape of a lead end is flat.

Enter “0” to the “Cut length” field.

⑪

Lead size

For a gullwing lead, enter the lead foot size here.

The “lead foot size” indicates the portion of a gullwing lead which is in contact with a board.

- In the example, the length of a gullwing lead foot is 0.5 mm.

Enter the following values:

Width : 0.2 (same as the lead width)

Length : 0.4

Here, you have finished entering element data. When you click the <OK> button

displayed on the lower right corner, the “Element Group” screen reappears.

● You have finished defining the first element group. When you click the <OK> button

displayed on the lower right corner, the “Element Data” screen reappears.

 When you have the next element group to be defined at this point, click the <Add> button to

define the element group by entering data in the same manner.

In the example, there are four element groups. Define four element groups.

Ball components (Element group/Element format) 6.5.2

This section describes the procedure for creating data on ball components (complex array

components).

1. Operation on the “Element Data” screen

- Select “Ball Component” from the “Component Type” combo box.

- Check the “Element group/Element format” check box in the “Define data format” field.

- Click the <Add> button on the “Element Group List.”

2. Operation on the “Element Group” screen

Define an element group.

An element group consists of components whose size and pitch is the same as each other.

A complex array component refers to an area array component whose size is different or

whose ball/land pitch is different from each other.

When the lead pitch is not the same even though the polarity is the same, set element

groups separately. If the polarity is the same, the size and shape of the polarity is the same

also.

In the example shown a complex array component that consists of four element groups is

shown.

◆ Description

The procedure for creating data on this component is to be described below.

The element size and pitch of the second and third element groups are the same as each

another. However, columns of elements are not aligned with each another. Define them as

two different element groups.

The posture of a complex array component is viewed from the bottom in the same manner as

an area array component such as a BGA and FBGA.

When a component has a staggered pattern of elements partially as shown in the figure, divide

them into two grid arrangement groups, then define them.
