Mobile phone and computer repair shops, motherboard factories, etc. will all see them using ultrasonic cleaners to clean motherboards.

  So why use an ultrasonic cleaner to clean the motherboard? The main cause was water ingress, which led to mold and rot on the motherboard, resulting in a short circuit. There are various problems such as no startup and no display. Before the advent of ultrasonic cleaners, many people chose brushes to clean. However, some parts of the motherboard were difficult to clean manually, such as the motherboard being sealed by a metal cover plate. The cleaning was not thorough and the effect was poor, and it was also time-consuming and laborious.

  The first breakthrough in the application of ultrasonic cleaning machines was in the electronics industry, and it is also the most well-known application in the electronics products industry, because the cleaning effect of ultrasonic cleaning machines on motherboards far exceeds that of other cleaning methods.
 
  How are you going to clean after having an ultrasonic cleaner? What kind of cleaning solution should be placed? Can water be added? I'll tell you very professionally that it's best not to use water as the cleaning solution, as water may cause the motherboard to mold and rot again. But if you can only choose water washing, be sure to dry it thoroughly with an air gun or a hair dryer.
 
  It is recommended to use alcohol to clean the mainboard with an ultrasonic cleaner. Banana water (commonly known as board cleaning water) is used as a cleaning solvent. After adding the cleaning agent, place the motherboard and clean it for a few minutes. Relatively speaking, banana water (board cleaning water) has the best cleaning effect. However, banana water (board cleaning water) is highly corrosive, and some plastic parts on the motherboard are not corrosion-resistant (especially computer motherboards). Therefore, considering all factors, alcohol is the best choice! < / span > < / p > < p > < br / > < span style = "font - size: 16 px" > PS: You can use either board cleaning water or alcohol to clean the mainboard of a mobile phone. The mainboard of a mobile phone is different from that of a computer. The plastic on the card slot of a mobile phone mainboard can withstand a temperature of around 200 degrees (except for a few poorly made mobile phones).
