Put the metal into the ultrasonic humidifier can play a role in cleaning metal?

The board before the factory generally have to go through the cleaning process, generally with a special washboard water, the board will be cleaned and dried after a new look and then packaged for shipment.　　This wash water after deionization and de-static treatment, will not corrode and breakdown circuit boards.　　In fact, we can do it ourselves to clean the motherboard, a little more sophisticated, then go to buy a special washboard water, or else use a non-conductive secondary distilled water to ensure that the cleaning of the water does not carry static ions.　　Note that it is best not to use the mineral water we often drink (containing too many ionic impurities), and do not use tap water, such water is often weak acid or alkaline, easy to corrode the circuit board.

If you're not sure about complete drying, it's best to unplug the batteries, integrated blocks, etc. from the board before cleaning, in short, unplug everything you can. During the cleaning process, use a softer brush and be careful not to touch the parts and solder joints, capacitors and so on.　　Generally speaking, CPU slots, AGP slots, PCI slots, underneath the Southbridge and Northbridge chips, underneath each integrated circuit IC chip, next to the memory slots next to the metal contacts, and underneath the BIOS chips, are not easy to clean and dry places.　　Scrubbing can also be done with an ultrasonic cleaner (usually available in optical stores) to clean dirt that is hard to scrub or invisible, but at the same time may cause damage to the components.　　Before drying, we can speed up the evaporation of water by brushing alcohol on the motherboard. Drying the motherboard can be done with a home hairdryer, or you can take it to a mechanic's store and blow it dry with a high-pressure air pump.　　It is best to use a dryer with a higher air flow so that the water can be forced out of the places that are not easy to dry. The drying must be thorough, otherwise it will lead to a local short circuit, and then the scrap may not just be the motherboard.　　In addition, the motherboard should be dried for some time after drying, it is best to use a baking lamp (or household lamp) for another 24 hours to ensure that there is no water vapor present when the power is added.　　Following this principle, the circuit boards of the CPU, boards, RAM and even hard disks in the computer's mainframe can be taken out and cleaned. It is important to note that if it is confirmed that the failure is not due to too much dust, or not to the point of no return, it is best not to clean the parts simply for the sake of looking good, after all, the risk of doing so is quite high.
