Is it safe to solder an MRF24J40MD module using vapor phase soldering?

We do NOT recommend vapor phase soldering unless it is clearly stated in the datasheet with temperature, tolerance and time. The "Soldering Recommendations" section of the MRF24J40MD datasheet reads:

To avoid damaging the module, we recommend doing the following:

  1. Refer to the solder paste datasheet for specific reflow profile recommendations.
  2. Use no-clean flux solder paste.
  3. Do not wash as moisture can be trapped under the shield.
  4. Use only one flow. If the PCB requires multiple flows, apply the module on the last flow.

Board level solder processes, such as IR reflow and vapor phase reflow, are well-known areas where temperatures can reach levels sufficient to cause failure of the package integrity. A plastic semiconductor package forms a rigid system where the various components are locked together. Differences in the physical expansion rate of materials result in internal package stresses because the constituent parts cannot move.
