1. An apparatus comprising:

  • a low-pressure chamber defining an interior and having the interior configured for placement of an electronic device in the interior and removal of the electronic device from the interior,at least one evacuation pump connected to the low-pressure chamber;

    a heater connected to the low-pressure chamber;

    at least one control system connected to the at least one evacuation pump and to the heater, the at least one control system controlling removal of moisture from the electronic device by controlling the at least one evacuation pump to decrease pressure within the low-pressure chamber, and controlling operation of the heater to add heat to the electronic device, wherein the at least one control system is further configured for;

    controlling at least one of the at least one evacuation pump or a valve in the low-pressure chamber to increase the pressure within the low-pressure chamber such that the increased pressure is substantially equal to pressure outside the low-pressure chamber, the decreasing the pressure and the increasing the pressure comprising a first cycle,repeating the controlling the at least one evacuation pump to decrease the pressure within the low-pressure chamber and the controlling the at least one of the at least one evacuation pump or the valve to increase the pressure within the low-pressure chamber such that the increased pressure is substantially equal to the pressure outside the low-pressure chamber, the repeating of the decreasing the pressure and of the increasing the pressure comprising a second cycle, anddetermining whether to stop or continue removing the moisture from the electronic device based on data from at least one of the first cycle or the second cycle.
