Board Definition
The model selected from the “Board Definition” dialog box is selected
automatically and the corresponding combo box is disabled.
For a Block PCB
Select the model for which setup will be performed and set other items.
<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
Set the size of Top / Bottom mark in X direction.
<Size X> edit box
The X position value of the Top / Bottom Mark.
<Size Y> edit box
The Y position value of the Top / Bottom Mark.

Advanced Chip Shooter DECAN S2 Administrator’s Guide
Memo The shape of the Top / Bottom Mark is limited to square or round.
The minimum size of the Top / Bottom Mark is as follows:
In the case of a square: horizontal, vertical angle 0.5mm or more
In the case of a round: a diameter of 0.5mm or more
<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.

Part Registration
Chapter7. Part Registration
The <Part> command is used to register components necessary for PCB operation and edit
data.
Part data is composed of “Align Data” and “Common Data”.
Align Data
Consists of information related to part recognition
Common Data
Consists of parameters related to part feeding device, nozzle for part pickup and
placement, pneumatic condition and driving speed
The component data managed by MMI include PCB Part, Local Part, and Standard Part
DB.
PCB Part: Parts registered in the PCB file
Local Part DB [UPD.mdb]: Parts registered after installing MMI in the equipment
Standard Part DB [STDUPD.mdb]: Simultaneous installation with MMI is DB
managing the data for standard parts (Read only)
Each PCB controls component data on all components operated on the corresponding PCB
and saves the component data in the Local Part DB of the machine.
To create component data for a new PCB, component data stored in the Local Part DB can
be copied. To create component data for a new component whose data is not stored in the
Local Part DB, data for a similar component stored in the Local Part DB can be copied and
edited or standard component data can be copied from the Standard Part DB and edited.
The Standard Part DB is a DB of generally used components developed and supplied by
this machine manufacturer. The relationship between component data is shown in the
following.
