5.1.6
Use

on
each
side
of
the
board
and
obtain
tape
results
for
one
tape

5.2
Evaluation
5.2.1
Report
the
tape
peel
strength
in
kg/cm
width.
5.2.2
Report
the
locus
of
failure
of
peeled
tape
(see
Note
1
.).
The
requirement
of
specifying
the
locus
of
mode
of
failure
of
the
tape
is
very
important
and
a
critical
aspect
of
the
test.
In
order
to
be
consistent
with
descriptions
of
failure
modes,
a
common
set
of
criteria
is
used,
as
defined
in
Table
2.
Figure

shows,
in
schematic,
the
various
failure
modes
one
could
obtain
during
performing
this
test.
The
three
layers,
from
bottom
to
top,
are
the
epoxy/glass
substrate,
(2)
the
adhe¬
sive
component
of
the
tape,
and
(3)
the

(see

5.2.3
Report
the
average

the
two
tape
peel

for
the
same
side
of
both
