METHODS

Scope
This
test
is
to
determine
the
ability
of
a
printed
pattern
of
solder
paste
to
retain
a
probe
placed
in
the
solder
paste
by
measuring
the
force
required
to
separate
the
probe
from
the
paste.
Time
between
printing
and
probe
placement
are
progressively
increased
to
simulate
variables
in
a
manu¬
facturing
process.

Test
Specimen
A
representative
sample
of
this
paste
should
then
be
printed
out,
using
a
stencil,
onto
clean
plain¬
glass
slides.
At
least
six
paste
deposits
should
be
printed
per
required
time
data-point.
The
final
deposits
must
be
circular,
6.3
mm
in
diameter
and
0.25
mm
thick.
Mark
the
test
speci¬
men
in
a
suitable
manner
to
identify
the
sample
and
the
time
after
printing
when
tackiness
is
to
be
measured.
The
prepared
samples
shall
be
stored
at
25℃
±
2
℃
and
50℃
土
1
0%
rela¬
tive
humidity
(RH)
until
evaluated.
The
samples
shall
not
be
stored
in
an
enclosed
cabinet
or
container,
which
allows
the
solder
paste
solvent
vapors
to
saturate
the
environment
sur¬
rounding
the
printed
paste,
thus
preventing
natural
drying
of
the
material.

Equipment/Apparatus
A
Chatillon
tackiness
tester
or
other
equipment
may
be
used,
providing
it
is
capable
of
accu¬
rately
measuring
force
when
tested
at
a
similar
velocity.
The
equipment
shall
have
a
stainless
steel
test
probe
with
a
nomi¬
nal
5.1
mm
±
0.13
mm
diameter
bottom
surface,
which
is
smooth,
flat,
and
aligned
parallel
to
the
plane
of
the
subject
test
specimen.
The
probe
shall
contact
the
test
specimen
at
a
controlled
speed
and
apply
a
controlled,
fixed
initial
contact
force.
Finally,
a
means
shall
be
provided
to
withdraw
the
test
probe
from
the
surface
of
the
test
specimen
at
a
controlled
speed
and
record
the
peak
force
required
to
break
contact
with
the
test
specimen.

Procedure
Place
the
specimen
slide
under
the
test
probe
and
center
the
probe
over
one
of
the
three
printed
pat¬
terns.
Bring
the
test
probe
in
contact
with
the
printed
paste
specimen
at
a
rate
of
2.5
mm/min.

and
apply
a

and
record
the

required
to

Take
at
least
five
additional
measurements
under
the
same
test
conditions
and
average
all
the
readings.
Record
both
the
tack
force
and
time
following

printing.
5.1
Evaluation
Initial
measurements
are
to
be
taken
imme¬
diately
after
printing.
Subsequent
measurements
of
force
shall
be
taken
as
needed
to
best
define
the
rise
and
decline
of
the
tack
force.
Tackiness
data
should
be
presented
in
graph
form,
provided
that
the
graph
with
tack
force
is
plotted
as
a
func¬
tion
of
time
after
printing.
The
data
can
also
be
reported
as
follows:
1.
Time
to
reach
80%
of
the
peak
value.
2.
The
peak
tack
force
in
grams
with
the
expected
variation.
3.
Time
over
which
the
peak
value
is
maintained
or
for
the
tack
force
to
decline
to
80%
of
its
peak
value.
