Cleaning
When the Copernicus GPS module is attached to the user board, a cleaning process 
voids the warranty. Please use a “no-clean” process to eliminate the cleaning process. 
The silver plated Copernicus GPS module may discolor with cleaning agent or 
chlorinated faucet water. Any other form of cleaning solder residual may cause 
permanent damage and will void the warranty.
Soldering Guidelines
Repeated Reflow Soldering
The Copernicus GPS lead-free silver plated module can withstand two-reflow solder 
processes. If the unit must mount on the first side for surface-mount reflow, add glue 
on the bottom of the module to prevent falling off when processing the second side.
Wave Soldering 
The Copernicus GPS module cannot soak in the solder pot. If the carrier board is 
mixed with through-hole components and surface mount devices, it can be processed 
with one single lead-free wave process. The temperature of the unit will depend on 
the size and the thickness of the board. Measure the temperature on the module to 
ensure that it remains under 180 °C.
Hand Soldering
For the lead-free Copernicus GPS module, use a lead-free solder core, such as Kester 
275 Sn96.5/Ag3/Cu0.5. When soldering the module by hand, keep the soldering iron 
below 260 °C.
Rework 
The Copernicus GPS module can withstand one rework cycle. The module can heat 
up to the reflow temperature to precede the rework. Never remove the metal shield 
and rework on the module itself.
Conformal Coating
Conformal coating on the Copernicus GPS module is not allowed. Conformal coating 
will void the warranty.
