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 rerecognition is greater than 0.1 it recognizes the angle after

correcting the angle. It 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) Generally this fuction is not

used.

<Real Display/Binary> Shows the image seen through the VisFrame in real display to which threshold is not

applied, or in the image (Binary) to which threshold is applied as recognized by MMI.

<Offset

<X> edit box

Set the X offset value to be added when the component is placed (After component

recognition, it is the value added after placement point adjustment.) If a component is not

top/down or right/left symmetry and when the component center(centroid) is calculated after

component recognition, it does not coincide with the actual component center. The purpose

of this value is to do regular adjustment by setting the offset value between the obtained

component center(centroid) and the actual component center.

<Y> edit box

Set the Y offset value to be added when the component is placed. (After component

recognition, the value added after component placement point adjustment)

<R> edit box

Set the R offset value to be added when the component is placed.(After component

recognition, it is the value added after component placement point adjustment)

<Ignore Center

Offset>

The Center Offset means that if a part was picked up at a point deviated from

the center of the part by a certain distance, it will be dumped regardless of

the part search result.

Therefore, if this function is selected for chip part, the Center Offset is

not checked when performing vision check.

That is, it means that the part will not be placed according to the search

result. If this function is not selected, the machine will dump the part when

it is picked up with its pickup point being deviated from the center by more

than 20% compared to the size of the part.

The reason to dump the part is that if it is picked up with the pickup point

being greatly deviated from the part center, the placement accuracy decreases

because the extent of the part movement becomes great according to the

corrected value after correction.

This is applied only to Chip-rect, Chip-tantal, Chip-Aluminum, Melf, etc.

<MFOV Type> Setup the type of multi-recognition. This function is activated only when

‘Fix1 Cam ~ Fix2 Cam’ is selected in the <Camera No.> combo box.

Selectable types are as follows

- None : Does not use multi-recognition type.

- Cross 2P : Performs multi-recognition of the two diagonal edges.

- Cross 4P : Performs multi-recognition of four edges.

- Linear H : Performs multi-recognition horizontally in two parts.

- Linear V : Performs multi-recognition vertically in two parts.

<MFOV Length> Input the moving distance for multi-recognition

<EX Param> Indicates the dialog box used to set up details related to recognition. In the

case of the general part, the recognition related details do not need to be

set. This is applied only to SOP, SOP2, SOJ, SOJ2, QFP, PLCC, UserIC, BGA,

Flip-Chip.

<Moveˇ>

Used for parts recognition test by manually picking up parts.

<Test>

Tests component recognition by using the set align data

Helps to specify the optimum lighting value.

Automatically finds out the component align data. If Auto Teach is successfully performed,

following dialog box is displayed

* Auto Teach is supported only for CHIP-Rect, TR, TR2,BGA, SOP, SOP2, SOJ,

SOJ2, QFP, PLCC and FLIPCHI.

<Make Image> Displays the component shape recognized by the MMI through the SMVision window

by assembling the split images after performing split recognition of the

component.
