7.1.1. Common Align Data

Provides details concerning the align data commonly applied to all parts.

 <Camera No.> combo box

 Fly Cam: Selects the fly camera of the head.

Memo The fly camera for recognizing each head is as follows:

 Fly Cam1: Head #1~Head #2 of the front gantry

 Fly Cam2: Head #3~Head #4 of the front gantry

 Fly Cam3: Head #5~Head #6 of the front gantry

 Fly Cam4: Head #7~Head #8 of the front gantry

 Fly Cam5: Head #9~Head #10 of the front gantry

 Fix Cam1: Select the fix camera.

 button

Sets the lighting for the camera to recognize the component. When this button is

clicked on, the following dialog box is displayed.

Figure7.8 “Camera No. =Fix Camera“ dialog box

 <Side> slide bar

Set a value for the side light. (0 –15)

 <Outer> slide bar

Set a value for the outer light. (0 - 15)

 <Inner> slide bar

Set a value for the outer light. (0 - 15)

 <OK> button

Saves the set light value and closes the dialog box.

 <Cancel> button

Closes the dialog box without saving the set light value.

Table7.1 Use of the Fix Camera Lighting

 <Size> group

 <Align Z> edit box

Set the height for recognition. Based on the component surface, if the top is to be

recognized, set - value, and if the bottom is to be recognized, set +value.

 <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

Light Use Applicable Part Remarks

Side Lights the edge of a part Chip, QFP, BGA, SOP etc

Outer Lights round edge of a

part or part surface

each pixel should be recognized in white or black.

 <Auto> check box

Check this box to set the <Threshold> value automatically.

 <Tolerance H[+]> edit box

In general, a part has a manufacturing tolerance. When the size of the recognized

part is larger than that in the registered part data, if its tolerance is not considered,

its inspection result will be no good.

Therefore, when recognizing a part, input the extent of the allowable difference

between the actual size and registered size as a percentage.

That is, when the value obtained by recognizing an actual part with the vision

system is greater than the input value, if the actual data value is allowed up to 1.3

times of the input data, the upper allowable error is 30%.

For the following chip parts, set the parameters referring to the following. For

other chip parts, it is recommended that the default setup be used.

 Chip-Circle

An allowable error is applied not to the length but to the area.

If an allowable error is applied to 10% of the diameter, the square of the

diameter must be applied. Therefore, 21% of the diameter is actually applied.

(Tolerance (H, L) = 1.1×1.1=1.21 )

 Chip-C 0402 / Chip-R 0402 / Chip-C 0603 / Chip-R 0603/ Chip-R 1005

Set it to a value greater than the one to be set by more than 10%. For example,

when setting 20%, actually apply 30%.

 <Tolerance L[-]> edit box

If the size of the recognized part is smaller than the registered part data, input the

allowable error as a percentage.

That is, when the actually recognized value is smaller than the input value, if the

actual data value is allowed up to 0.7 times that of the input data, the lower

allowable error is 30%.
