METHODS

Scope
This
test
method
establishes
a
procedure
for
determining
whether
the
adhesion
of
a
polymer
coating
to
an
inorganic
or
ceramic
substrate
is
above
an
adequate
level.
The
substrate
may
or
may
not
have
an
oxide
layer
on
the
sur¬
face.
The
test
can
be
inverted
and
used
for
determining
the
adhesion
of
a
metal
coating
to
a
polymer
film.

Test
Specimen
The
test
specimen
shall
consist
of
the
coated
substrate.
A
control
should
also
be
prepared
using
a
mutually
agreed
upon
material
whose
results
from
this
test
are
known,
preferably
a
material
with
an
adhesion
classification
of
5.
At
least
3
test
specimens
should
be
prepared
for
each
material
of
interest.

coating
onto
the
surface
of
the

5.2
Pattern
Coating
The
coating
should
be
patterned
according
to
the
procedures
outlined
in
section
4.2.5
of
IPC-
DD-135.
The
pattern
consists
of
a

tures,
as
illustrated

At
least
two
complete
grids
must
be
patterned
on
the
specimen,
one
for
the
initial
test
and
one
for
the
3
hour
test.

Test
5.3.1
Remove
two
complete
laps
of
tape
and
discard.
Remove
an
additional
length
at
a
steady
(not
jerked)
rate
and
cut
a
piece
approximately
75
mm
[3.0
in]
long.
5.3.2
Place
the
center
of
the
tape
over
one
of
the
grid
pat¬
terns
and
smooth
into
place
by
a
finger.
Rub
the
tape
firmly
with
the
eraser
on
the
end
of
the
pencil
to
ensure
good
con¬
tact
between
the
tape
and
the
film.
The
color
under
the
tape
is
a
good
indicator
of
contact
between
the
tape
and
the
film.

Within
90
seconds
of
applying
the
tape,
remove
the
tape
with
a
steady
motion
by
pulling
at
a
1
80°

5.3.4
Inspect
the
lattice
pattern
under
illumination
for
removal
of
coating
from
the
substrate.
Rate
the
adhesion
in
accordance
with
the
following
scale
illustrated
in
Figure

The
edges
of
the
line
patterns
are
completely
smooth;
none
of
the
squares
of
the
lattice
are
detached.
•

Small
flakes
of
the
coating
are
detached
at
the
intersection
of
the
lattice;
less
than
5%
of
the
area
is
affected.
•

Small
flakes
of
the
coating
are
detached
along
the
edges
and
at
intersections
of
the
lattice.
The
area
affected
is
5
to
1
5%
of
the
lattice.
•

The
coating
has
flaked
along
the
edges
and
on
parts
of
the
squares.
The
area
affected
is
1
5
to
35%
of
the
lattice.
•

The
coating
has
flaked
along
the
edges
of
the
line
patterns
in
long
ribbons
and
whole
squares
have
detached.
The
area
affected
is
35

65%
of
the
lattice.
•

Greater
than
65%

the
lattice

detached.
5.3.5
Place
the
test
specimens
in
a
boiling
water
bath
and
stress
the
samples
for
3
hours.
The
water
in
the
boiling
water
bath
must
completely
cover
the
test
specimens
for
the
entire
3
hours.
A
closed
system
that
returns
the
steam
as
conden¬
sation
is
preferred.
5.3.6
Remove
the
test
specimens
from
the
boiling
water
bath
or
environmental
chamber
and
allow
to
cool
to
room
temperature.
5.3.7
Wipe
sample
dry.
Repeat
steps
5.3.1
-5.3.4
on
the
second
(unused)
grid
pattern.
5.3.8

for
both
the
initial
and
