Procedure
5.1
Prepare
specimens
as
required,
depending
on
the
con¬
figuration
of
the
material
under
test
(see
3.1).
5.2
Preconditioning
The
samples
and
controls
shall
be
dried
by
baking
at
1
05℃
土
2
℃
for
a
minimum
of
two
hours
to
remove
moisture.
5.3
Expose
to
Moisture
Under
Pressure
5.3.1
Place
three
pieces
of
each
type
of
material
to
be
tested
in
the
pressure
vessel,
such
that
they
are
vertical
by
use
of
a
rack
or
grooved
block,
which
does
not
cover
more
than
5%
of
the
surface
area
of
the
specimen.
If
samples
have
been
prepared
as
per
3.
1.2.
2
and
3.1
.3,
place
one
piece
of
the
base
laminate
in
the
vessel
along
with
the
specimens.
5.3.2
Fill
the
pressure
vessel
with
water
such
that
the
speci¬
mens
are
not
sitting
in
the
water.
5.3.3
Close
the
lid
of
the
pressure
vessel
and
seal
the
chamber.
5.3.4
Apply
heat
to
the
pressure

until
the
temperature
and
pressure
specified
are
attained
and
held
constant.
5.3.5
Water

All
safety
precautions
must
be
exercised
when
working
with
a
mixture
of
dry
ice
and
alcohol.
6.1.1
Dry
ice
has
a
temperature
of
-1
10°F,
passes
directly
to
the
gaseous
state,
and
is
used
as
a
refrigerant.
Therefore,
it
is
dangerous
if
not
handled
carefully.
6.1.2
Isopropyl
alcohol
is
flammable
and
toxic;
should
not
be
ingested,
and
should
also
be
handled
properly.

1 Scope
This test method describes the procedure for
establishing the service temperature for metal-clad flexible
base material (laminate) as described in IPC-4204 as well as
cover materials and adhesive bonding films (unsupported
adhesive and supported bond plies) as described in IPC-
4203. For purposes of this test method, cover material
consist of coverlay and coverfilm but include cover-
coat materials. Properties evaluated after thermal aging in this
test are: visual, peel strength and dielectric strength.

3.1 Specimen Preparation for Metal-Clad Flexible Base
Material (Laminate)
3.1.1
Prepare twelve specimens according to the procedure
outlined for method A of IPC TM-650, method 2.4.9, using
appropriate photolithographic processes. Etch four conduc-
tors 3.2 mm [0.126 in] wide, 5.7 mm [0.224 in] pitch, 230 -
250 mm [9 - 10 in] long on a nominal 25 mm [1 in] wide strip
of flexible base dielectric (see Figure 1).
Single-clad or double-clad flexible base material
be
tested in the format supplied. If the flexible base material
under test is double-clad, prepare a separate set of speci-
mens for each side. It is permissible to leave the unetched
copper on the non-test side (see Notes 6.1 and 6.2).
3.2 Specimen Preparation for Cover Material
3.2.1
Single-clad base material be produced from
specimens of the cover materials. Cover material
be
bonded to the shiny side of 34.3 µm [1.35 mil] copper foil,
type CU-E1-1S or CU-E7-1S per IPC-4562 (CU-E1-1S
be the referee material). Copper foil cleaning be per the
manufacturer’s normal cleaning procedure. The referee clean-
ing procedure
be per Table 1.
3.2.2
Prepare twelve specimens according to the procedure
outlined for method A of IPC TM-650, method 2.4.9, using
appropriate photolithographic processes. Etch four conduc-
tors 3.2 mm [0.126 in] wide, 5.7 mm [0.224 in] pitch, 230 -
250 mm [9 - 10 in] long on a nominal 25 mm [1 in] wide strip
of flexible base dielectric (see Figure 1).
3.3 Specimen Preparation for Adhesive Bonding Film
3.3.1
Metal-clad flexible base material be produced
from specimens of the adhesive bonding film being evaluated.
Adhesive bonding film
be bonded to the shiny side of
34.3 µm [1350 µin] ED copper foil, type CU-E1-1S or RA
copper foil, CU-E7-1S per IPC-4562 (CU-E1-1S
be the
referee material). Adhesive bonding film
be bonded
between the copper foil and CU-E1-1S as support material as
illustrated in Figure 2. Copper foil cleaning
be per the
manufacturer’s normal cleaning procedure. The referee clean-
ing procedure
be per Table 1, the same as detailed in
IPC-4203.
Prepare specimens according to the procedure outlined for
method A of IPC TM-650, method 2.4.9, using appropriate
