prior
to
testing.
The
paste

shall
be
sufficient

Equipment/Apparatus
The
equipment
used
shall
be
a
spindle
type
viscometer
(Brookfield
RVTD
or
equivalent)
with
a
reversible
helipath
stand
and
pen

shall
be
used
for
tests
and
operated
at
5
rpm.
Other
equipment
may
be
used
provided
the
results
can
be
empirically
corre¬
lated
as
mutually
agreed
upon
with
the
following
test.
Addi¬
tional
shear

Procedure
5.1
Preparation
5.1.1
Open
the
supply
container(s);
remove
any
internal
cov¬
ers),
scrape
off
paste
adhering
to
the
lid(s),
internal
covers,
and
the
container
walls;
and
add
this
material
to
the
paste
in
the
supply
container(s).
5.1.2
Using
a
spatula,
stir
the
paste
gently
for
1
to
2
minutes
to
homogenize
it;
taking
care
to
avoid
the
introduction
of
air.
5.1.3
If
necessary,
gently
transfer
the
paste
to
the
test
con¬
tainer
having
the
specified
volume;
without
introducing
air.
If
the
supply
container
meets
the
volume
and
size
requirements
a
separate
test
container
is
not
needed.
5.1.4
The
test
container
shall
be
placed
in
a
constant
tem¬
perature
environment
at
25
±
0.25℃.
The
solder
paste
shall
remain
stationary
for
a
minimum
of
two
hours
to
reach
tem¬
perature
and
rheological
equilibrium.

Set
the
bottom
stop
for

travel
to
position
the
T
spindle
at
2.8
cm
below
the
surface
of
the

test
container.
The
bottom
stop
of
the
spindle
shall
be
a
minimum
of
1
cm
above
the
bottom
of
the
container.
Set
the
upper
stop
to
position
the
spindle
at
0.3
cm
below
the
surface
of
the
solder
paste.
5.2
Test
5.2.1
Immerse
the
spindle
in
the
solder
paste
and
record
data
for
10
minutes
(5
cycles).
The
temperature
of
the
solder
paste
during
the
test
shall
be
maintained
at
25
土
0.25℃.
5.3
Evaluation
Viscosity
is
to
be
expressed
at
the
value
calculated
from
the
average
of
the
peak
and
valley
of
the
last
two
cycles.
If
the
average
for
the
first
two
cycles
is
more
than
10%
higher
than
the
last
two
cycles,
the
test
is
invalid
and
additional
equilibrium
time
is
required.
Record
data
and
