Table 11: Recommended conditions for reflow process
The peak temperature must not exceed 250°C. The time above 245°C must not exceed 30 seconds.
AMY-6M must not be soldered with a damp heat process.
3.3.3 Optical inspection
After soldering the AMY-6M module, consider an optical inspection step to check whether:
The module is properly aligned and centered over the pads
3.3.4 Repeated reflow soldering
Only single reflow soldering processes are recommended for boards populated with AMY-6M modules.
3.3.5 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 AMY-6M.
3.3.6 Rework
Not recommended.
3.3.7 Conformal coating
Certain applications employ a conformal coating of the PCB using HumiSeal
Conformal Coating of the module will void the warranty.
3.3.8 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 u-blox 6 module before implementing this in the production.
Casting will void the warranty.
3.3.9 Use of ultrasonic processes
Some components on the u-blox 6 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 u-blox 6 module caused by any Ultrasonic Processes.
