Slant virtual plane allowance
This is displayed when the slant virtual plane detection is set to
"Enable (Manual)". Enter the slant virtual plane allowance value.
When "0" is set, the slant virtual plane detection will
not be decided.
Accuracy
Auto (Default) :
The measurement accuracy (standard/high accuracy) is
automatically set, based on the component data.
Standard :
The test is performed at standard-resolution level.
SOP, QFP, Connector:
This is set when the lead pitch is 0.4 mm or more.
BGA, CSP :
This is set when the ball pitch is 0.8 mm or more and the
ball diameter is 0.5 mm or more.
High accuracy :
The test is performed at high-resolution level.
SOP, QFP, Connector :
This is set when the lead pitch is less than 0.4 mm.
BGA, CSP :
This is set when the ball pitch is less than 0.8 mm and
the ball diameter is less than 0.5 mm.
Luster condition
Auto (Default) :
The component characteristics (lead luster degree) are set
automatically. In the case of leaded components, the half-
luster lead is set. In the case of BGA and CSP, the luster
ball is selected.
Luster :
The component characteristics (lead or ball luster degree)
are set to "Luster". In the case of leaded component, when
the surface is palladium- or gold-plated, the lead is strongly
reflected, set it to "Luster". In the case of the ball, "Luster"
is usually set.
Half-luster :
The component characteristics (lead luster degree) are set
to "Half-luster". With a general leaded component, set it to
"Half-luster".
Non-luster :
The component characteristics (lead or ball luster degree)
are set to "Non-luster". When the lead or ball is not a
reflected component, set it to "Non-luster".

Laser power
Auto :
The laser power is set to "7" (Maximum).
From 1 to 7 :
The laser power can be changed between 1 and 7. When
the lead (ball) is reflected too much and there is a bright
alarm error, reduce the laser power.
Dark cut level set
Auto (Default) :
The dark cut level is set to the following values, depending
on the settings for component characteristics.
In the case of Leaded Components
Luster: 60, Half-Luster: 40, Non-Luster: 20
Solder Ball Component
Luster: 40, Half-Luster: 40, Non-Luster: 20
Manual :
The dark cut level can be set manually.
Dark cut level
This is indicated when the dark cut level is set to "Manual". It
is set when the dark cut level has to be adjusted, depending
on the lead image, resulting from checking the indicated
distance and image of the V. bend detection sensor head
after recognition test.
AGC range
Auto (Default) :
The AGC (Auto Gain Control) is set to "2" for gull wing and
J bend leaded components. It is set to "3" for straight and
solder ball components.
From 1 to 5 :
The AGC can be set in the range of 1 and 5.
When the difference between reflections of leads is
great and the V. bend detection result is not stable,
reduce the value.

XY posn detn
Auto (Default) :
The XY posn allowance is set automatically. Normally, it is
set to 0.3 mm.
Disable :
The XY posn detn for each lead is not decided.
(Unavailable)
Enable :
The XY posn allowance is set manually.
XY posn allowance
It is displayed when the "XY posn detn" is set to "Enable".
The XY posn allowance for each lead is entered.
Lead sampling posn set
Auto (Default) :
If the lead shape is gull wing, it is set to "0.1 mm"; if J
bend, it is set at a value corresponding to a half the lead
length.
Manual :
The Lead sampling posn sis set manually.
This function is valid only when the lead shape is gull wing
or straight.
Lead sampling posn
It is displayed when the "Lead sampling posn set" is set to
"Manual". The location where the lead height is detected is
designated depending on the distance from the lead end.
