Part III Inspection Algorithm

1.13 IC_Solder2

1.13.1 Inspection Overview

IC_Solder2 is the algorithm to inspect lead’s length and shift, solder condition and lifted lead in one

inspection window with high accuracy.

It automatically locates “inspection points” (lead end, lead base, pad end) on an IC component.

Inspection ﬂ ow is as following; lead length, lead shift, solder, copper, and lifted lead.

CAUTION

If lead length or lead shift inspection is NG, all the following inspections, solder,

copper and lifted lead inspections are skipped.

CAUTION

IC_Solder2 is not available for two lighting system machine. It is also not valid in

combination with Part III 1.22 AS_Av_LeadLength.

Parameter Description

Engineer Mode

Engineer Mode enables to set detailed settings for parameters.

To set parameters with bar charts, remove the check mark.

Lead length

Enter measured value in lead length.

Lead width

Enter measured value in lead width.

Range

Search range for an edge between a lead end area and a pad lead area.

This lead Displays measured lead length.

Fat solder OK

Judges heavy solder amount as OK.

Dark solder NG

Judges small solder amount as NG.

Use dryjoint Detects dryjoint.

White body

It is useful to search a component body which is brighter than a lead base.

NOTE

Check a radio button. The corresponding histogram appears in the lower right side

of the screen.

NOTE

When Inspect is pressed, a colored circle may appear on the left side of the radio

button for some inspecton results. Red refers NG and white refers skip inspection.

1.13.3 Setting Procedure

Step1: Adjust the size of the inspection window to surround the lead base to pad end. Window

width should be the same as pad width.

Step2: Lead length and width will be displayed in the upper right corner of the dialog if left-clicking

a lead base and dragging the pointer to opposite corner of the lead end. Enter the window

size shown in the upper right side of the dialog in Lead length and Lead width.

CAUTION

Do not measure the lead size at the lead of the selected inspection window,

otherwise the inspection window is misaligned.
