SAM-M10Q-Integration manual
The best approach is to use a “no clean” soldering paste to eliminate the cleaning step after the
soldering.
Repeated reflow soldering
Repeated reflow soldering processes or soldering the module upside down are not
recommended.
A board that is populated with components on both sides may require more than one reflow
soldering cycle. In such a case, the process should ensure the module is only placed on the board
submitted for a single final upright reflow cycle. A module placed on the underside of the board may
detach during a reflow soldering cycle due to lack of adhesion.
The module can also tolerate an additional reflow cycle for rework purposes.
Wave soldering
Base boards with combined through-hole technology (THT) components and surface-mount
technology (SMT) devices require wave soldering to solder the THT components. Only a single wave
soldering process is encouraged for boards populated with modules.
Rework
We do not recommend using a hot air gun because it is an uncontrolled process and can damage
the module.
Use of a hot air gun can lead to overheating and severely damage the module. Always avoid
overheating the module.
After the module is removed, clean the pads before reapplying solder paste, placing and reflow
soldering a new module.
Never attempt a rework on the module itself, e.g. by replacing individual components. Such
actions will immediately void the warranty.
Conformal coating
Certain applications employ a conformal coating of the PCB using HumiSeal® or other related
coating products. These materials affect the RF properties of the GNSS patch antenna module.
Conformal coating of the module will void the warranty.
Casting
Casting materials affect the RF properties of the GNSS patch antenna, including resonant
frequency shifts, and are not recommended for antenna modules.
Casting will void the warranty.
Use of ultrasonic processes
Some components on the module are sensitive to ultrasonic waves. Use of any ultrasonic processes
(cleaning, welding etc.) may cause damage to the receiver.
u-blox offers no warranty against damages to the module caused by ultrasonic processes.
Oxidation of patch antenna
The patch antenna is metalized by silver paste and thus tends to oxidize and changes color. This is
normal and is not a case for warranty.
