Because of the mobility of the phone , allowing users to use the process , will inevitably result in water or moisture. And because of highly integrated GSM phone's internal circuitry , the band working in the 900MHz or 1800MHz. So when the phone is water, on the one hand because the water may be accumulating a variety of impurities and electrolytes , causing the circuit board defaced , may cause circuit failure . Especially when the phone is switched on after the water without washing and drying , plus electrode easily lead directly integrated phone lines and power supply circuit board failure. On the other hand , when the influent water evaporation phones , the circuit board may leave many impurities and electrolytes, will directly change the circuit board in the design of the distribution parameters , resulting in performance indicators declined. Therefore , when the mobile water , to go through the proper process to fix the phone .

    Over the water into the cell phone is easy to break , but what line easily broken it? One is easily broken power lines , power lines is because a large current work place , into the water if the phone fails to be processed in a timely manner , when a short-circuit power supply is easy to burn off . Another is the line perforation , because the accumulation of corrosion perforation is easy and difficult to remove , Over time, most perishable disconnected. Third, the IC pin small components such as resistors , capacitors and most corrosive .

    For users sent water machine, first of all, the situation on the ultrasonic cleaning instrument for washing , cleaning fluid can be used ethanol or water that day, using the vibration of the ultrasonic cleaning circuit boards and integrated circuits various impurities bottom of the module and electrolytes clean . Secondly , soaked in water for a long time mobile phone, must be dry cleaned . Because the longer soaking time , water may have entered the inner layer circuit board . At this time , if not necessarily a simple method of cleaning water in the inner circuit board can be completely ruled out . This is when you need to soak the board in anhydrous alcohol , and soaking time should be long enough ( usually 24-36 hours ) , the use of ethanol in water absorption, moisture and anhydrous alcohol completely mixed , and then , the circuit board placed in the oven for drying, the temperature controlled at about 60 ~ C , and dried 24 hours in general , the basic rule of the inner layer circuit board moisture .
