When
the
cause
of
a
failure
lies
in
specific
components
or
lots
,
the
components
must
be
examined
first
of
all
.

are
the
cases
of

whose
factors
lie
in

Machine
-
Based
Factors
When
a
component
has
no
problem
,
check
the
main
body
of
the
machine
.
A
failure
can
be
tracked
by
checking
if
it
occurs
on
a
specific
vacuum
nozzle
or
feeder
slot
No

When
a
failure
occurs
on
a
specific
vacuum
nozzle
,
check
the
following
items
concerning
the
pertinent
vacuum
nozzle
.
①
Check
if
the
nozzle
is
abnormal
.
②
Check
if
the
vacuum
line
is
abnormal
.
③
Check
if
the
vacuum

valve
is
abnormal
.
When
a
factory
is
dusty
or
a
lot
of
components
packaged
in
paper
tapes
are
used
，
the
vacuum
nozzles
and
their
filters
get
dirty
easily
.
Therefore
,
it
becomes
important
to
clean
the
periodically
