 <1.Use> check box

Set whether to use the Accept Mark.

 <2. Mark Position> group

The Accept Mark position teaching result is inputted.

 <3. Teach> group

Teach the Accept Mark position.

Procedure to teach the Accept Mark

Select the fiducial camera corresponding to the workstation to which a PCB is

loaded.

Click the <<Move> button to move to the position of the currently set Accept

Mark.

Perform adjustments so that the Accept Mark center falls on the crosshair center in

the SMVision window.

Click the <Get> button to input the current coordinate.

 <4. Mark Type> group

Select the color of Accept Mark. Available mad mark colors are as follows;

Black: the mark appears darker than the surrounding.

White: the mark appears brighter than the surrounding.

 <5. Search Area> group

Set the area to test the Accept Mark. The purpose is to limit the testing area when

recognition is interfered due to a shape similar to the mark near the mark.

<Width X> edit box

Set the range to test in X axis direction. In general, set to 6mm.

<Width Y> edit box

Set the range to test in Y axis direction. In general, set to 6mm.

 <6. Mark Size> group

The size of the Accept Mark is displayed.

<Size X> edit box

The horizontal size of the Accept Mark is displayed. The size is changed based on

the value set in the <Width X> edit box of <5. Search Area> group.

<Size Y> edit box

The vertical size of the Accept Mark is displayed. The size is changed based on

the value set in the <Width Y> edit box of <5. Search Area> group.

 <7. Parameter> group

<Threshold> edit box

The image viewed through the SM Vision window is composed of each 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.

For example, if accept mark setup is “Black” and the <Threshold> value is 100, all

values under 100 in the vision image are recognized as black. And if <Accept

mark Logic> is “White” and the <Threshold> value is 100, all values over 100 in

the vision image are recognized as white.

<Real Display/Binary> button

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

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

by MMI.

<Light> group

Set the lighting value when testing the Accept Mark. In general, set to 7. However,

adjust it properly according to the condition of the PCB and accept mark.

<Test> button

Tests the mark by using the set mark data. The user can check whether the set

mark data is correct. When the test is successful, the following message box is

displayed..

Caution If you move to another screen while editing the “Board”

dialog box, the edited data is saved automatically

 <Update> button

Save the Accept Mark data and close the “Accept Mark Position” dialog box.

 <Cancel> button

Close the “Accept Mark Position” dialog box without saving the Accept Mark data.

6.6. 2D Barcode

6.6.1. Configuration

Allows a user to know the model information of the PCB loaded into the machine by

recognizing the 2D barcode on the PCB and manage the production history by interlocking

PCB with the Lot Tracking System (LTS).

In addition, it is possible to save production time by transmitting the information from the

board recognized by the first equipment to the next equipment.
