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.

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.
