3.3.10 Conformal Coating
Certain
applications
employ
a
conformal
coating
of
the
PCB
using
HumiSeal
®
or
other
related
coating
products.
These
materials
affect
the
HF
properties
of
the
GPS
module
and
it
is
important
to
prevent
them
from
flowing
into
the
module.
The
RF
shields
do
not
provide
100%
protection
for
the
module
from
coating
liquids
with
low
viscosity,
therefore
care
is
required
in
applying
the
coating.
Conformal
Coating
of
the
module
will
void
the
warranty.
3.3.11 Casting
If
casting
is
required,
use
viscose
or
another
type
of
silicon
pottant.
The
OEM
is
strongly
advised
to
qualify
such
processes
in
combination
with
the
TIM-5H
module
before
implementing
this
in
the
production.
Casting
will
void
the
warranty.
3.3.12 Grounding Metal Covers
Attempts
to
improve
grounding
by
soldering
ground
cables,
wick
or
other
forms
of
metal
strips
directly
onto
the
EMI
covers
is
done
at
the
customer's
own
risk.
The
numerous
ground
pins
should
be
sufficient
to
provide
optimum
immunity
to
interferences
and
noise.
u-blox
makes
no
warranty
for
damages
to
the
TIM-5H
module
caused
by
soldering
metal
cables
or
any
other
forms
of
metal
strips
directly
onto
the
EMI
covers.
3.3.13 Use of Ultrasonic Processes
Some
components
on
the
TIM-5H
module
are
sensitive
to
Ultrasonic
Waves.
Use
of
any
Ultrasonic
Processes
(cleaning,
welding
etc.)
may
cause
damage
to
the
GPS
Receiver.
u-blox
offers
no
warranty
against
damages
to
the
TIM-5H
module
caused
by
any
Ultrasonic
Processes.
