of
Deficiency
Angular

)
was
generated
by
2
or

%
during

placement
.

.
Cause
Wrong
recognition
was
made
due
to
the
dirty
end
of
the
vacuum

was
cleaned
and
the

.
Cause
A
square
component
was
recognized
by
the
comer
detection
function
but
no
recognition
error
occurred
and
the
component
was
placed
because
X
and
Y
were
equilateral
although
it
was
on
the
skew
by
90
°
when
picked
up
.
These
two
electrical
contacts
were
recognized
as
leads
.

.
Remedy
The
component
was
recognized
as
a
leaded
one
，
so
that
a
recognition
error
occurred
when
the
component
was
shifted
by
90
°
