TEST
METHODS
MANUAL
1
Scope
This
test
method
covers
acceptance
of
incoming
copper
clad
epoxy-glass
laminates
ranging
in
thickness
from
0.8
mm
to
6.5
mm,
clad
on
one
or
both
sides.
It
provides
for
a
standard
method
of
inspection
and
establishes
operations
that
simulate
the
manufacture
of
PWBs.
Specific
values
for
the
acceptability
are
based
on
copper
foil
adhesion
and
visual
surface
condition
of
the
base
laminate.

3.1
Specimen
One
specimen
shall
be
tested
for
each
sample,
except
in
the
case
where
material
is
clad
on
both
sides,
in
which
case
two
specimens
shall
be
processed
for
each
sample
(one
for
each
surface).
Each
specimen
will
have
four
readings.

Sampling
The
sampling
procedure
will
be
to
MIL-STD-
