First of all, why would you ever do this?
Whoever thought of this method is a doody brains, It doesn't do anything.
Go ahead and take your sad hard drive out of the freezer.
Google Wave , Reflow Soldering:
The problem with wave soldering is the amount of heat that can be applied is based on the smallest component.... which means that large components, power connections for example that carry a large amount of current / and or heat up don't get enough heat during the soldering process. The net result is a "cold-solder" joint on large components which greatly increases them developing cracks in the solder joint over time.
Wave soldering vs Reflow soldering- which is much better:
Regardless of what process is used the more the device is turned ON and OFF (Cycled) the more the board/device/joint is stressed. A device which is left on 24/7 will last much longer than a device that gets to temp, then is shut off frequently.
