11. PLCC
11.1. Side Lead Fitting
Suitable for PLCC components where the lead reflection is uneven, with
recognition not possible in the "Normal" algorithm.
When the end lead is detected, the positional relationship of the leads is
checked, and the pairing that most closely matches the component definition is
selected in order to increase the recognition rate.
Particular parameters
Lead Search The position used as the datum
of positioning is specified. In the case of
"Top", outward lead tip section is detected, and in the case of "Root", inner
lead tip section is detected.
Excessive Lead
Check
If “Check” is specified, when the component whose lead pitch and width are
same and which have excessive leads is supplied, it becomes an error. In “No
Check”, the check is not performed.
Lead Search Filter
The amount of application of luminescent spot removal is specified.
Right Angle Fitting
The extraction method of side leads is specified. If “Off”, the extraction method
by the usual distance relation is applied. If “On”, the method which give priority
to the degree of rectangular cross of two sides is applied. Usually, it specified
“Off”. When the right side leads which have the section with luminosity
unevenness are hard to be detected, if “On” is specified, a recognition rate will
increase.

11.2. NS Base Search
Suitable for PLCC components where images of the WE direction leads are
unclear, with recognition not possible in either the "Normal" or "Side Lead
Fitting" modes.
SOJ recognition occurs using the NS direction leads first, with that result
being used as a reference for detecting the WE direction leads.
Particular parameters
Lead Search The position used as the datum of positioning is specified. In the case of "Top",
outward lead tip section is detected, and in the case of "Root", inner lead tip
section is detected.
Excessive
Lead Check
If “Check” is specified, when the component whose lead pitch and width are same
and which have excessive leads is supplied, it becomes an error. In “No Check”,
the check is not performed.
11.3. WE Base Search
Suitable for PLCC components where images of the NS direction leads are
unclear, with recognition not possible in either the "Normal" or "Side Lead
Fitting" modes.
SOJ recognition occurs using the WE direction leads first, with that result
being used as a reference for detecting the NS direction leads.
Particular parameters
Lead Search The position used as the datum of positioning is specified. In the case of "Top",
outward lead tip section is detected, and in the case of "Root", inner lead tip
section is detected.
Excessive
Lead Check
If “Check” is specified, when the component whose lead pitch and width are same
and which have excessive leads is supplied, it becomes an error. In “No Check”,
the check is not performed.

11.4. Check Direction
Suitable for determining the direction of PLCC and QFP
components.
A direction judgment is made by comparing the average
brightness of the specified circle area with a 180 degrees
opposing circle area. Suitable where a polarity mark, etc., exists
on the recognition face.
Particular parameters
Lead Search The position used as the datum of positioning is specified. In the case of "Top",
outward lead tip section is detected, and in the case of "Root", inner lead tip
section is detected.
Excessive
Lead Check
If “Check” is specified, when the component whose lead pitch and width are same
and which have excessive leads is supplied, it becomes an error. In “No Check”,
the check is not performed.
Lead Search
Filter
The amount of application of luminescent spot removal is specified.
Right Angle
Fitting
The extraction method of side leads is specified. If “Off”, the extraction method by
the usual distance relation is applied. If “On”, the method which give priority to the
degree of rectangular cross of two sides is applied. Usually, it specified “Off”.
When the right side leads which have the section with luminosity unevenness are
hard to be detected, if “On” is specified, a recognition rate will increase.
Check Type When it is expected that the brightness of the specified circle will be brighter than
the brightness of a rotation symmetry position, “White” is specified. Else “Black” is
specified.
Check
Direction
The direction at which a direction judging is performed is specified.
In distinguishing 0 and 180 degrees, “2 Angle” is specified. In distinguishing 0, 90,
180, and 270 degrees, “4 Angle” is specified.
Judgment
Method
Action after a direction check is specified. When the "Error" is specified, if an
angle difference is detected, it becomes an error. An angle is compensated when
"Angle Correction" is specified.
Min.
Brightness
Difference
The difference in the average brightness of detection circles being checked in
order to differentiate the directions must be larger than this value, or an error will
occur. If 0, 50 will be set.
Direction Mark
Diameter (mm)
The diameter of the circle where brightness is measured is specified.
Direction Mark
Center X
Direction Mark
Center Y
The center position of the circle where brightness is measured is specified.
