Chapter 6 General-Purpose Vision Component

General-Purpose Vision Components 6.1

Overview of a general-purpose vision component 6.1.1

The following types of components are handled as a general-purpose vision component

- Components having multi-pitch leads, components having various sized leads, and

components having leads at not-regulated positions (these components are called

“multi-lead” components.)

- Area array components having two or more arrays (called “complex array components.)

- Components having balls/lands on not-regulated positions (called “random component”.)

- Components having a side or corner (outline-recognition components)

• The components above are classified into the following sub-component types:

− Multi-lead component: Lead component group

− Complex array component and random array components: Ball component group

− Outline-recognition component: Outline-recognition component group

A group of the same recognition elements is called an “element group.” In other words, an

element indicates a lead or a ball, and an element group indicates a group of elements of the

same size (leads or balls).

For a general-purpose vision component, a group of elements that are arranged in the same

manner is handled as one element group. By defining each element group, the system can

obtain the center of the component. A general-purpose vision component shown in Figure

consists of four element groups.

(3) Shape and size specifications of an outline-recognition component group

- The specifications of the corner/side shape are the same as those of the

outline-recognition component group.

(See “*Recognizing conditions for outline recognition components” of Section 4.3.5.2

(12) “Vision data” 13) “Outline-recognized component.”)

- A filled circle and square marks can be used.

A mark whose size is from 2 mm to 10 mm can be recognized with the VCS (54mm

view).

Procedure for Creating Data on a General-Purpose Vision Component 6.1.3

To create data on a general-purpose vision component, create data on each element group.

To create data on each element group, enter:

① Element information (such as whether an element is a lead or a ball, and size and shape of an

element)

② Number of elements and pitch between two consecutive elements

③ Distance between the component recognition center and the first element*

* The first element is defined as shown below:

− For a ball component: the first element is a ball located at the bottom left corner of an element group.

− For a lead component: the first element on the bottom side is located at the leftmost position, that on the

right side is located at the lowest position, that on the top side is located at the rightmost position, and that

on the left side is located at the top position.

Example: For the following general-purpose component, create data on four element groups (in

mm).

How to enter “1 Element information” is not described here. See the next page for

the detail on how to enter data.

• First element group

− Number of elements and pitch between two consecutive elements ⇒

Number: 30, Pitch: 1

− Distance of the center of a component to be recognized to the first element ⇒

X: - 14.5, Y: -4

• Second element group

− Number of elements and pitch between two consecutive elements ⇒

Number: 4, Pitch: 1.5

− Distance of the center of a component to be recognized to the first element ⇒

X: 21.5, Y: 4

• Third element group

− Number of elements and pitch between two consecutive elements ⇒

Number: 31, − Pitch: 1

− Distance of the center of a component to be recognized to the first element ⇒

X: 15, Y: 4

• Fourth element group

− Number of elements and pitch between two consecutive elements ⇒

Number: 4, − Pitch: 1.5

− Distance of the center of a component to be recognized to the first element ⇒

X: - 17, Y: 4

When you enter information described above, data on a general-purpose vision component is

created completely.
