 Inspection option:

- Polarity component: Refer to polarity item (page5-23)‟ in '5.3.1 mounting inspection

window‟ Spot improvement: use this to fill inside of the character with white for binarization

of character part.

- Character/background setting: set contrast between character string and component body.

 Select „White/Black‟ when character string is white and body is dark.

 Select „Black/White‟ when character string is black and body is white.

 Matching Option

- Matching ratio

 If character string is not found using OCR‟s recognition algorithm, conduct inspection

using algorithm that is used for mounting inspection. At this point, normal judgment

reference matching value that is used.

- Search range

 Set search area to find character string that completed teaching in X/Y pixel unit.

 Pattern image screen

- Refer to „pattern image screen (page5-25)‟ in '5.3.1 mounting inspection window‟

 Character edit

- This function is used for users to directly register character in order to increase recognition

rate of various character fonts on component. The following is the way to register it.

① Click <character teaching> button.

② If font of character desired to be registered differs from font of already registered character,

select character font to be registered as shown in the figure below and enter character to be

registered in data box on the left of <Add> button and then click <Add> button to register the

relevant font.

③ To edit font of character desired to be registered, click <Edit> button in user font

 If it is found using OCR character recognition algorithm, extract characteristic of each

character to display the searched result.

[Figure 5-73 Inspection result of OCR’s character recognition algorithm]

 If it is found using pattern matching, use pattern matching to show that character string is

recognized.

5.3.5 Binary inspection window

- Binary inspection can conducts various inspections like line width, edge position, solder

ball, scratch and component center in binary image (image expressed by black and white)

or black and white image (image consisted of pixels with 255steps (black 0 ~ gray 128 ~

white 255) of luminance).

- The followings are detailed inspection types of binary inspection.

Stripe width inspection

position move inspection

solder ball inspection

Tap inspection

multiple tap inspection

eccentricity inspection

Component center

comparison inspection

1) Teaching method – commons

① Click <binary inspection window> button among operating buttons.

② Draw binary inspection window in inspection area.

③ Select inspection type.

④ Select X coordinate compensation and Y coordinate compensate. If necessary, select one or

select none.

⑤ Select whether to judge defect as normal
