Using heating and drying to deal with water in the U disk can shorten the dehydration time of the U disk, but the damp circuit board inside the U disk dries quickly due to external heat, but the water in the U disk cannot be synchronized. Volatile. At this time, due to the internal stress, the U disk circuit board will rupture and cause circuit damage, so our simple heating and drying method is incorrect.
And many people do not do any pre-processing before drying the U disk. Although the U disk will not be short-circuited after water enters the U disk, when we use a hair dryer to dry it or dry it, as time goes by The evaporation of water, salt and other impurities contained in the water adhere to the circuit board. These things are often electrical conductors. When we insert the U disk into the computer, the U disk may be damaged when the U disk is powered on!
Correct handling method:

If conditions permit, it is recommended to use absolute alcohol to clean the U disk. (It is best to disassemble the U disk and take out the circuit board) The above work is best done immediately after the U disk enters the water. If the U disk is not processed in time and is allowed to dry naturally after the U disk enters the water, it may be damaged when the power is turned on. When the circuit board is short-circuited. Finally, we put the U disk in a ventilated place and let it dry naturally!
