<Size> group

Set the align size.

<Total Y> edit box

Displays the size of the whole component in Y direction. It is calculated and

displayed when <Body Y> and <Lead Length> are determined. ( <Body Y> +

<Lead Length> * 2)

<Outline> button

Displays the outline of the component by using the set align data.

<Move…> button

Performs component pickups or moves to the stage camera.

Please refer to “7.2.1.1 Common Align Data (Page 7-9)” for more information.

Tests component recognition by using the set align data. Please refer to “7.2.1.1

Common Align Data (Page 7-9)” for more information.

<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.

<Lead Pitch> edit box

Set the lead pitch

<Lead Foot> edit box

Set the length of the lead that touches the surface.

<Lead Length> edit box

<Option> group

Set the align option data.

<Area Margin> edit box

Set the limit for the image to be off the center of the screen when the component

is recognized. For example, if this value is 5mm, the component image should be

within 5mm of the center of the screen.

<Tolerance Tangential> edit box

Set the allowance tolerance when the lead is pushed to the side. Set it as a

percentage of <Lead Pitch>.

<Threshold> edit box

When there is a pre-treatment process for component recognition and the gray

level image is converted into binary, it is the value used as the criteria to

determine black and white.

The value range is 0 – 255(0: black, 255: white), and this value serves to

differentiate the component from the background. When the set value is 0, the

value is set automatically during component recognition.

<Auto> check box

Check it to set the <Threshold> value automatically.

<Binary> button

Displays the binary image of the component on the Vision Monitor screen.

<Repeat Angle> edit box

In the case of the work needed for high precision, this re-recognizes and pick-up

and placement of the component by performing correction according to the

vision recognition result. For example, if o.i is inputted for the repeat angle, it

corrects the angle after vision recognition and re-recognizes it. If the result of re-

repeats this until the result of the recognition become less than 0.1. When the

value becomes 0.1, it pick and place the component (it tries recognition up to 4

times)
