The logic expression allows a comprehensive evaluation for judgment through combination of the
inspection result judgments for individual fillet and electrode posture inspection items, which can
facilitate the reduction of false calls.

List of Inspection Names for Fault Image and Wettability Inspection
Fault Image
Inspection Name
Description
Lifted Electrode
Judged faulty if the electrode lifts and its toe
is higher.
Electrode Protrusion
Judged faulty if the electrode bends upward
and its diagonal length is longer.
Electrode Vertical Bend
Judged faulty if the electrode bends upward
or downward.
Electrode Horizontal
Bend
Judged faulty if the electrode bends in a
horizontal direction.
Electrode Wettability
Height
Judged faulty if solder joint with the electrode
is not sufficient.
Electrode Wet
Judged as a fault if the solder wetting height
is low and forms a flat surface around the
electrode.
Electrode Wet Convex
Judged faulty if solder forms a flat line in the
proximity of the electrode.
Solder Convex
Judged faulty if solder forms a convex shape
between the solder tip and the electrode.
Land Wettability Length
Judged faulty if solder does not spread
sufficiently in the land length direction.
