Soldering Recommendations

The MRF24WN0MA/MB wireless module was assem-
bled using the IPC/JEDEC J-STD-020 Standard lead-
free reflow profile. The MRF24WN0MA/MB module
can be soldered to the host PCB using standard leaded
and lead-free solder reflow profiles.
To avoid damaging the module, adhere to the following
recommendations:
• Solder reflow recommendations are provided in 

the Microchip Application Note, 

AN233 "Solder 

Reflow Recommendation"

 (DS00233)

• Do not exceed a peak temperature (T

P

) of 250°C

• Refer to the solder paste data sheet for specific 

reflow profile recommendations from the vendor

• Use no-clean flux solder paste
• Do not wash as moisture can be trapped under 

the shield

• Use only one flow. If the PCB requires multiple 

flows, apply the module on the final flow.
