⑪ Contrast

Set the “contrast between a pin (ball) and molding section of a BGA

component”, or set the “recognition pattern for an outline-recognized

component”.

1) For a BGA

• Setting items

Table 5.5.3.1

Selection on the

pop-up menu

Recognition range Type

PWB PWB type whose molding section looks black

Ceramic

Recognizes balls on the

outer frame only.

Ceramic type whose molding section looks white

All balls Ball recognition by a pattern

All land

Recognizes all balls of a

component.

All land recognition of an LGA

If you change the setting of this item to “PWB” or “Ceramic” after you

select “All balls” or “All land” and set a ball pattern, the ball pattern is

initialized.

• How to set

When you click this setting item with the right button, the selection

pop-up menu appears on the screen.

2) For an outline-recognized component

• Setting items

Table 5.2.3.2

Selection on the pop-up

Recognition method

4sides

Recognizes a component with four sides of a rectangle. This setting is

effective for a rectangle component whose corner is unclear.

4corners Recognizes a component with four corners of a rectangle.

Center

Recognizes a component by calculating the center of the substance which

is currently being shot.

• How to set

When you click this setting item with the right button, the selection

pop-up menu appears on the screen.

3) Limitation on components depending on the recognition method

(A) Side recognition

Recognition conditions:

① Components whose whole shape is a rectangle or regular square

② Components whose linear portion (line segment) of a side is 1/2 or more of

the component outline size but whose linear portion (line segment) should

be 3 mm or more

③ Components whose side middle section is straight: 1.5 cm on both sides of

the center.

④ Components whose component angle is within 90° ± 0.5°.

⑤ Components whose sides are 0.3 mm or more when their insides are

imaged darkly at imaging

0.3mm or more

⑥ Components whose side roughness forming a linear portion is 0.1 mm or

less

0.1mm or less

⑦ Components whose component shape is not convex.

When the above conditions are satisfied, side recognition is enabled.

(B) Corner recognition

Recognition conditions:

① Components whose whole shape is a regular square or rectangle

② Components whose corner angle R is 0.5 mm or less

③ Components whose linear portion length forming each side is 2 mm or more

2.00 mm

0.5 mm

④ Components whose 4 corner points are at vertexes of a regular square or

rectangle

⑤ Components whose outline is not convex

⑥ Components with concave portions whose L1 is 10% or less of L2

⑦ Components whose sides are 0.3 mm or more when their insides are

imaged darkly at imaging

0.3mm or more

⑧ Components whose side roughness forming a linear portion is 0.1 mm or

less

0.1mm or less

♦ When the above recognition conditions are satisfied, corner recognition is

enabled.
