8 Storage, Manufacturing & Packaging
8.1. Storage Conditions
The module is provided with vacuum-sealed packaging. MSL of the module is rated as 3. The storage requirements are shown below.
1. Recommended Storage Condition: the temperature should be 23 ±5 °C and the relative humidity should be 35­60 %.
2. Shelf life (in a vacuum-sealed packaging): 12 months in Recommended Storage Condition.
3. Floor life: 168 hours 24 in a factory where the temperature is 23 ±5 °C and relative humidity is below 60 %. After the vacuum-sealed packaging is removed, the module must be processed in reflow soldering or other high- temperature operations within 168 hours. Otherwise, the module should be stored in an environment where the relative humidity is less than 10 % (e.g., a dry cabinet).
4. The module should be pre-baked to avoid blistering, cracks and inner-layer separation in PCB under the following circumstances:
The module is not stored in Recommended Storage Condition; Violation of the third requirement mentioned above; Vacuum-sealed packaging is broken, or the packaging has been removed for over 24 hours; Before module repairing.
5. If needed, the pre-baking should follow the requirements below:
The module should be baked for 8 hours at 120 ±5 °C; The module must be soldered to PCB within 24 hours after the baking, otherwise it should be put
in a dry environment such as in a dry cabinet.

24 This floor life is only applicable when the environment conforms to IPC/JEDEC J-STD-033. It is recommended to start the solder reflow process within 24 hours after the package is removed if the temperature and moisture do not conform to, or are not sure to conform to IPC/JEDEC J-STD-033. Do not unpack the modules in large quantities until they are ready for soldering.

RG500L_Series_QuecOpen_Hardware_Design

97 / 114

5G Module Series
NOTE 1. To avoid blistering, layer separation and other soldering issues, extended exposure of the module to
the air is forbidden. 2. Take out the module from the package and put it on high-temperature-resistant fixtures before baking.
If shorter baking time is desired, see IPC/JEDEC J-STD-033 for the baking procedure. 3. Pay attention to ESD protection, such as wearing anti-static gloves, when touching the modules.
8.2. Manufacturing and Soldering
Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. Apply proper force on the squeegee to produce a clean stencil surface on a single pass. To guarantee module soldering quality, the thickness of stencil for the module is recommended to be 0.15­0.18 mm. For more details, see document [5].
The recommended peak reflow temperature should be 235­246 ºC, with 246 ºC as the absolute maximum reflow temperature. To avoid damage to the module caused by repeated heating, it is strongly recommended that the module should be mounted only after reflow soldering for the other side of PCB has been completed. The recommended reflow soldering thermal profile (lead-free reflow soldering) and related parameters are shown below.

NOTE
1. The above profile parameter requirements are for the measured temperature of the solder joints. Both the hottest and coldest spots of solder joints on the PCB should meet the above requirements.
2. If a conformal coating is necessary for the module, do NOT use any coating material that may chemically react with the PCB or shielding cover, and prevent the coating material from flowing into the module.
3. Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the module. 4. Due to the complexity of the SMT process, please contact Quectel Technical Supports in advance for
any situation that you are not sure about, or any process (e.g. selective soldering, ultrasonic soldering) that is not mentioned in document [5].
