 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

- Refer to „reference name (page5-21)‟ in „5.3.1mounting inspection window‟ excepting

shape.

- Created in „_BIN_0‟ format. „BIN‟ means Binary and the number means the creation order

of binary inspection window.

 Component name

- Refer to „component name (page5-21)‟ in '5.3.1 1mounting inspection window‟.

 Rotation angle

- Refer to „rotation angle (page5-22)‟ in '5.3.1 1mounting inspection window‟.

 Defect type

- Refer to „defect type (page5-22)‟ in '5.3.1 1mounting inspection window‟.

 Light type

- Set light for inspection of inspection window that completed teaching. Select light type that

clearly displays characteristic according to inspection type and inspection area.

 Image type

- Set light for inspection of inspection window that completed teaching. Select image type

that clearly displays characteristic according to inspection type and inspection area.

 X coordinate compensation, Y coordinate compensation

- If many inspection windows are group to inspect one component, position of other

inspection window can be compensated referring to X/Y offset measured in mounting

inspection window.

- X/Y coordinate compensation is to select whether to conduct position compensation

referring to X/Y offset measured in mounting inspection window.

- As shown in [Figure 5-93], if X/Y coordinate compensation is not used, binary inspection

window doe not move in offset of mounting inspection window. However, in case of using

X/Y coordinate compensation, binary inspection window moves as much as offset.

[Figure 5-76 Use example of X/Y coordinate compensation function]

 Judge as good for defect

- Change inspection result judged as defect to normal.
