Solder Joint Damage-Prevention Mode for a Computing Device
This document describes techniques and apparatuses including a solder joint damage-prevention mode for a computing device. In general, the computing device may enter the solder joint damage-prevention mode to transfer heat to solder joints and prevent failure mechanisms such as fracture, creep, and/or fatigue. The solder joint damage-prevention mode may rely upon one or more operations, including identifying a state of the computing device in or following which damage to the solder joints has an increased likelihood and, in response, activating a thermal-conditioning system. The thermal-conditioning system may, in general, increase a temperature of the solder joints to improve mechanical robustness of the solder joints.
