PROCESSING
Recommended Reflow Profile
Pb-Free Solder Paste
Use of “No Clean” soldering paste is strongly recommended, as it does not require cleaning after the soldering process.
Note:
Specification. See the latest IPC-A-610 Acceptability of Electronic Assemblies, Castellated Terminations section.
Cleaning
In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed
with any cleaning process.
The best approach is to consider using a “no clean” solder paste and eliminate the post-soldering cleaning step.
Optical Inspection
After soldering the Module to the host board, consider optical inspection to check the following:
Repeating Reflow Soldering
Only a single reflow soldering process is encouraged for host boards.
Wave Soldering
If a wave soldering process is required on the host boards due to the presence of leaded components, only a single wave
soldering process is encouraged.
Hand Soldering
Hand soldering is possible. When using a soldering iron, follow IPC recommendations (reference document IPC-7711).

• Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and
• Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the two housings, which
• Ultrasonic cleaning could damage the module permanently.
• Proper alignment and centering of the module over the pads.
• Proper solder joints on all pads.
• Excessive solder or contacts to neighboring pads, or vias.
The quality of solder joints on the castellations (‘half vias’) where they contact the host board should meet the appropriate IPC
the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between
neighboring pads. Water could also damage any stickers or labels.
