Method for Restoring Damaged Electronic Devices by Cleaning and Apparatus Therefor

A method comprising regenerating damaged electronic device by a least one cleaning process and a least one drying process, the cleaning process further comprising the steps of:

• submerging one or more electronic devices into an aqueous cleaning liquid in a cleaning chamber,
• subjecting the aqueous cleaning liquid and the one or more electronic devices to sonication
• the dying process comprises the step of:
• drying the one or more electronic devices
• wherein drying of the one or more electronic devices is done in a drying cycle by periodically heating the cleaning chamber and subjecting the cleaning chamber to reduced pressure and where the cleaning step and the drying step are carried out in the same cleaning chamber, and wherein the drying cycle comprises the steps of:
• a:
• heating air entering into the cleaning chamber to a temperature of at least 60° C. at a first reduced pressure of 0.5-0.9 bar,
• b:
• maintaining a chamber temperature of 35-80° C. and a second reduced pressure level of 0.5-0.9 bar,
• c:
• reducing the pressure to a third pressure level of 0.1-0.5 bar.
