Part III Inspection Algorithm

1.20 Barcode

1.20.1 Inspection Overview

Barcode is the algorithm to recognize 1D barcode. Register the target barcode.

The result will be OK digit number of recognized barcode is in tolerance.

Barcode is suitable for PCBs traceability.

NOTE

Refer to Part III 2.2 Barcode_Pro for 2D barcode inspection.

1.20.2 Parameter Setting

Figure 1-85 Barcode

Parameter Description

Lighting

Select a lighting that displays barcodes visually clear.

Algorithm Select Barcode.

Reduction Enter 4.

Reverse

Enter 0 if the brightness level of the barcode is lower than surrounding brightness.

Enter 1 if it is higher.

Barcode kind -

Shift[V1-V8]

Enter the appropriate vector. Any value from V1 to V8 is available.

Select the vector according to the Memorize to ﬁ eld of the Adjust window.

Version -

Memorize to -

Upper, Lower

Enter the barcode digit number in

Upper

ﬁ eld and Lower ﬁ eld. The sample value is the

digit number of recognized barcode. If the target digit and recognized digit number is the

same, the result will be OK.

Sample

This parameter shows the digit number of the recognized barcode.

1.20.3 Setting Procedure

Step1: Select a lighting that displays the barcode visually clear from the Lighting drop-down list.

Step2: Adjust the size of the inspection window to surround the barcode. Leave spaces at both

sides of barcode (make spaces three times wider than the widest blank space in the barcode).

Step3: Press Set in the right side of Algorithm. The dialog shown in Figure 1-87 appears.

Select the barcode kind and press OK.

NOTE

If BT_Autodetect for one dimension code is checked, the barcode type will be

recognized automatically. However, the inspection time will become longer.

Step4: Press Inspect. Make sure that the alphanumeric characters of the barcode are displayed

correctly on the upper right side of the dialog shown in Figure 1-85.

1.21 ASLeadLength

1.21.1 Inspection Overview

ASLeadLength is the algorithm to inspect leads length of IC components by measuring length from

lead base area to lead end area. Scanning with TopLight, brightness level of lead base area and lead

end area are bright. If lifted lead occurs, lead length is longer compare to normal condition.

If sample value is within OK range, the result will be OK.

ASLeadLength is suitable for lifted lead of IC components.

1.21.2 Parameter Setting

Figure 1-88 ASLeadLength

Parameter Description

Lighting

Select arbitrarily lighting.

Algorithm Select ASLeadLength.

Lead Top Area The inspection window size of lead end area (=yellow dotted line).

Search Range

Default is 10. Enter the bigger value to extend the search range of the lead end area.

LeadBase

The inspection window size of lead base area (=pink dotted line).

Search Range

Default is 10. Enter the bigger value to extend the search range of the lead base area.

Shift[V1-V8]

Enter the appropriate vector. Any value from V1 to V8 is available.

Select the vector according to the Memorize to ﬁ eld of the Adjust window.

Memorize to -

Upper, Lower

Make sure of a sample value of an OK lead. Enter the value (sample value plus 20) in

the Upper ﬁ eld and the value (sample value minus 20) in the Lower ﬁ eld.

Sample

Shows distance of lead end area to lead base area.
