Before handling the PCBA, they must be
cooled to 35°C or below after they have
gone through the reflow-soldering
process, in order to prevent positional
shift that might occur when the module is
still hot.
1. Can use electric fans
behind the Reflow
machine to cool them
down.
2. Cooling the PCBA can
prevent the module
from shifting due to
fluid effect.
It is very easy to cause
positional offset to the
module and its patch
antenna when handling the
PCBA under high
temperature.

1. When separating the PCBA panel into
individual pieces using the V-Cut process,
special attentions are needed to ensure
there are sufficient gap between patch
antennas so the patch antennas are not
in contact with one another.
2. If V-Cut process is not available and the
pieces must be separated manually,
please make sure the operators are not
using excess force which may cause
rotational offset to the patch antennas.
1. The blade and the
patch antenna must
have a distance gap
greater than 0.6mm.
2. Do not use patch
antenna as the leverage
point when separating
the panels by hand.
1. Test must be performed
first to determine if V-Cut
process is going to be used.
There must be enough space
to ensure the blade and
patch antenna do not touch
one another.
2. An uneven amount of
manual force applied to the
separation will likely to
cause positional shift in
patch antenna and module.

When separating pane
l into individual
pieces during latter half of the production
process, special attentions are needed to
ensure the patch antennas do not come
in contact with one another in order to
prevent chipped corners or positional
shifts.
Use tray to separate
individual pieces.
It is possible to chip corner
and/or cause a shift in
position if patch antennas
come in contact with each
other.

antennas (PA/Gms Module Series), and may not be applicable to all GPS modules.
