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.

①

Name

Name an element group to be handled. When you want to change an element group,

specify its name to edit it.

A name is automatically assigned with serial numbers. Users can change this numbered

name to an alphanumeric name (up to 32 characters).

- In the example, the numbered name is used.

②

First element position

Specify the position (X, Y) and direction (Theta) of an element group.

As the position, specify the distance (offset) from the center of a component. Normally, the

center of a component is the center of the component outline.

- If the placement coordinates set in Placement data of a production program is not based

on the center of the component outline, you can specify the coordinates of the reference

component center with coordinates different from the center of the component outline.

The figure indicates that the center of the component outline is the center of a

component.

 To be precise, the “First element position” is the distance

(offset) from the center of a component to the first element.

The direction (angle) of the element group is basically 0 degrees.

The figure shows the relation between the lines (rows) and

columns.

The first (ball or land) element positions at the coordinates of

the element (ball/land) at the lower left corner.

- This layout of elements is different from that of a standard

BGA component having balls on the outer frame.

 The figure shows the first element (ball/land) position of the component shown in the

example above.

For a ball/land element, the center of the first ball/land viewed from the center of a

component becomes the coordinates of the first (ball/land) element.
