Does water moisture freezing, i.e. expansion cause an issue with packages once they are placed?

  • We have never heard of an instance of a package/device failure caused by freezing after a product has been installed.  The amount of moisture picked up is very small.   There are small voids in the package that could accommodate any expansion from freezing.   But the steam created from entrapped moisture during solder re-flow can create much more pressure and cause a package fracture.
