Your cell phone can face several issues such as getting overheated (though this problem is common in some of the models), not switching on, battery getting discharged very soon, frequent freezing and hanging of your phone and so on. Sometimes, your phone may automatically restart if it is short. This problem is known as a short-circuit. Before you eliminate the shorting, it is imperative for you to know whether the circuit of your handset is short or not. Here are some of the simple ways for checking shorting in a mobile phone:
Causes for the shorting of a handset’s circuit board
⎫ You handset is overheated
⎫ The most common cause of such a problem is the mobile phone falling in water or getting drenched.
⎫ Using a faulty or an incompatible charger to charge your handset.
⎫ Smoke or sparks coming out of your mobile phone due to any reason.
Process for removal of shorting in mobile phones
1. Your mobile phone has to be dismantled so that the PCB or the printed circuit board can be taken out. You need to be cautious while doing so to prevent any type of damage to it. Your next step would be to remove parts like camera, LCD, and so on as it is just the board that is simply required.
2. A circuit cleaner like IPA, thinner, alcohol or spirit should be used for cleaning the entire printed circuit board thoroughly. You should next ensure that it is dried thoroughly. After the completion of each step, you should check whether the shorting has stopped or not. You should go to the next step only if the issue is not solved.
3. Your next step should be to make sure that the printed circuit board of your handset undergoes deep cleaning. Usually phone repair technicians use a liquid known as Elma. If you cannot get access to this solution, a solution made from a mild soap can be applied for thorough cleaning of the PCB.
The PCB has to be dipped in a mild soap solution or Elma for about 2 to 4 hours. The PCB should be removed from the solution and then cleaned properly with a brush. The PCB should then be dried thoroughly so that there is not a droplet of soap solution or water that remains on it. A dryer can be used for thorough drying of the PCB. Alternatively, direct sunlight or a flame can be used, though a hair dryer is the best option.
If the problem of shorting is resolved after cleaning the PCB, the cause may have been some dust particles that resulted in shorting. Dust is one of the bitter enemies that can hamper the smooth working of the circuit board of your handset. In case the problem persists, it best if you take your device to a Halifax phone repair store or call TDK Mobile.
