Step16: Enter the number of leads in Number of Electrodes and press OK.
Step17: Enter the appropriate vector into the Shift fi eld. Any value from V1 to V8 is available.
Select the vector according to the Memorize to fi eld of the Adjust window.
Step18: Press Inspect. Make sure that the inspection is completed properly.

1.14 IC_Solder3
1.14.1 Inspection Overview
IC_Solder3 is the algorithm to inspect the lead length, shift, bend, solder conditions, and lifted lead
in only one inspection window with high accuracy.
Operability has been improved from the conventional IC_Solder2 algorithm and now lead bend can
be inspected.
It automatically locates inspection points (lead end, lead base, pad end) of an IC component.
The algorithm inspects a lead length, lead shift, lead bend, solder, copper and lifted lead in order.
CAUTION
If lead length or lead shift inspection is NG, all the following inspections, solder,
copper and lifted lead inspections are skipped.
CAUTION
IC_Solder3 is not available for two lighting system machine. It is also not valid in
combination with Part III 1.22 AS_Av_LeadLength.

Table 1-23 Parameter 1 of IC_Solder3
Parameter Description
Inspection parameter
Select inspection parameter from the drop-down list to set. Refer to Part III 1.14.3
Setting Procedure.
Length Enter measured value in lead length.
Width Enter measured value in lead width.
Search range
Search range for edge between lead end area and pad lead area.
Fat solder OK
Judges heavy solder amount as OK.
Dark solder NG
Judges small solder amount as NG.
White body
It is useful to search component body which is brighter than lead base (e.g.,
Connectors).
Use dryjoint
Detects dryjoint.

NOTE
When Inspect is pressed, a colored circle appears in the left side of the radio button
according to the inspection result. Red refers NG and white refers skip inspection.
1.14.3 Setting Procedure
Step1: Adjust the size of the inspection window to surround the lead base to pad end. Window
width should be same as pad width.
