Operation
)
for
the
scope
of
actions
.
Process
A
:
A
component
is
picked
up
at
Station
®
5
and
transferred
to
Station
⑤
.
Process
B
:
The
component
recognition
function
is
implemented
on
the
component
at
Station
⑤
.
Process
C
:
The
placement

)
and
the
component
is
placed
on
the

Based
on
these
processes
，
failures
can
be
divided
roughly
into
the
following
two
types
.
•
Failure
before
Component
Placement
This
type
of
failure
occurs
mainly
in
Process
A
.
•
Failure
after
Component
Placement
This
type
of
failure
occurs
mainly
at
Processes
A
，
B
，
C
，
D
，
and
E
.
