Advanced Chip Shooter DECAN S2 Administrator’s Guide

Gull-Wing: Leads protrude outward as QFP.

J-Lead: Leads roll inward as PLCC.

 <Algorithm> combo box

Select the algorithm to recognize the component. Available algorithms are as

follows.

 Black Body

Used in case only lead is displayed brightly on the screen since the color of the

component body is black.

 All Body

Used in case lead and body are displayed brightly on the screen since the color

of the component body is bright.

 Odd with No Lead

Used for odd shaped parts for which recognition accuracy is not important. Its

recognition algorithm is similar to that of the trimmer.

 Odd with Lead

Used for odd shaped parts with leads.

 <Lead Parameter & Group> button

Set the lead parameter and lead group.

Please refer to“7.1.1 common Align Data”.

 <Option> group

Set the align option data.For other setups, please refer to“7.1.1 common Align Data”.

 <Use Polygon> check box

In the case of the part whose recognition precision is not significantly important,

this is used to recognize the part automatically using the Auto Teach function.

Adjust the Threshold and Ex Parameter to suit the characteristics of the

corresponding part so that it can be recognized automatically.

Selecting the <Use Polygon> check box will disable the <Lead Parameter &

Group> button and <MFOV Type> combo box. This enables the <Auto Teach>

button.

At this time, in the <Body X> and <Body Y> edit box of the <Size> group, set the

size of the area in which the polygon is to be searched.

The area in which the polygon is to be searched can be set up by adding the value

entered in the <Area Margin> edit box to the value set by the <Size> group.

Clicking the <Ex Param> button will display the following dialog box. The value

from 0 up to 10 can be set in the <Body Sub Sample> edit box of the <Extra

Parameter> tab dialog box.

The value set here determines the fineness when creating the outline of the part in

the SM Vision window.

If the image displayed in the SM Vision window has a lot of noise or is unclear, set

its value to the default value of ‘0’.

If the image is clear and therefore the outline of the part can be distinguished

plainly, the part outline can be created with fine detail.

However, if the outline becomes rough due to an over-increase in the value, the

part may not be recognized correctly.

10 –Roughest Outline

1: Polygon Toolbar

 Polygon Toolbar button

When recognizing a part, the part recognition center can be designated by

dragging the crosshair with the mouse.

At this time, the center of the camera becomes the part recognition center by

default. Match the recognition center (origin point) of the polygon part to be

recognized with the crosshair center. Then the crosshair center becomes the

center of the area in which the polygon part is to be searched.

 <Direction Mark> button

Sets the part placement direction.
