pixel.Each pixel has a unique value between 0 and 255 according to the

seen degree of brightness. Here, ‘Threshold Value’ indicates the border

value deciding whether each pixel should be recognized in white or black.

That is, setup the limitation for deciding if the image pixel should be black

or white when checking a bad mark.

The value can be adjusted by entering a numerical value in the edit box.

Check the <Auto> check box to automatically set up the <Threshold>

value.

 <Size X> edit box

Displays the area size in the X direction.

 <Size Y> edit box

Displays the area size in the Y direction.

 <Pos X> edit box

Displays the X coordinate of the area center..

 <Pos Y> edit box

Displays the Y coordinate of the area center.

 <Rotation> combo box

Selects the rotating angle of the direction mark. The rotation angle can be

selected according to the direction mark type as follows:

Triangle:

Circle: The angle cannot be selected.

H Mark:

 <Polarity> combo box

Select the color of fiducial mark. Available colors are as follows.

- White: the mark looks lighter than the surroundings.

- Black: the mark looks darker than the surroundings.

 <4 Way Search> check box

This function ensures that even when IC parts are supplied in an irregular

direction, they are mounted normally. When the <4 Way Search> check box is

selected, the head adsorbs a part, is rotated by 4 different angles (0/90/180/270

degrees), and then recognizes the direction mark of the part. At this time, the

recognized angle can be reflected to the mounting angle, and parts can be

mounted properly and according to the direction of each part.

The function can only be used for IC parts whose shape is circular but whose

internal pattern is QFP. (This function cannot be used for Ball type parts such

as BGA.)

 <Outline> button

Shows the image seen through the Vision in real display to which threshold is

not applied, or in the image (Binary) to which threshold is applied as

recognized by MMI.

 <OK> button

Saves the align data and closes the dialog box.

 <Cancel> button

Closes the dialog box without saving the align data.

 <Move> button

Used for parts recognition test by manually picking up parts. Please refer to “Common

Align Data” for more information.

 <Test> button

Tests component recognition by using the set align data. Please refer to “Common

Align Data” for more information.

 <Make Image> button

Displays the component shape recognized by the MMI through the SM Vision window

by assembling the split images after performing split recognition of the component.

 <Image Capture> button

Helps to specify the optimum lighting value. The lighting is gradually changed

automatically and the images are saved. The user can check the best image and

identify the optimum lighting value. Please refer to “Common Align Data” for more

information.

7.1.4.1. Lead Parameter

Sets the lead Parameter and lead group of the lead component.

Figure7.25 Screen showing “Lead Parameter” setting in the dialog box for “User IC Lead

Parameter & Group “

 <Lead Parameter> group

Set the lead parameter.

 <No.> column

Displays the lead parameter number. Possible range is 0 –7.

 <Width Type> column

Set the lead width.

 <Width Max> column

Input the maximum allowable lead width. (Input value = Lead Width + Allowable

Error). That is, even though the recognized lead is a maximum of 1.2mm when the

actual lead width is 1mm, if this recognized value is allowed, the maximum

allowable lead width will be 1.2mm

 <Width Min> column

Input the minimum allowable lead width. (Input value = Lead Width - Allowable

Error). That is, even though the recognized lead is a maximum of 0.8mm when the

actual lead width is 1mm, if this recognized value is allowed, the maximum

allowable lead width will be 0.8mm

 <Length Type> column

Set the lead length.
