Apply the trick: if we are surprised to find that the phone fails after using the wind gun to weld IC or blow dry with a hair dryer.However, after the phone has cooled down for a period of time, the failure will occur again, and the failure will disappear again after heating, so that we can use this method to find the tiny points of failure.This method is very good, you might as well try!Specific instructions: heating the local device with a soldering iron, if heating the CPU, the cell phone can signal, the failure may be on the CPU, we can try to change the CPU;If the heating medium frequency IC or audio IC malfunction may be in the audio or medium frequency IC;Heating 13MHz master clock clock crystal, there is a signal that the fault of the phone may be that the clock crystal is not able to vibrate.In particular, many mobile phones have no signal that the frequency of 13MHz occurs when there is no signal. We can use heat to determine whether the phones signal is caused by the 13MHz master clock.In addition, this method is also effective for audio IC and intermediate frequency IC failures.On the surface of the actual maintenance, the method of local heating can identify fault parts, and the method of heating the whole machine can blur the faults of some phones. the theory basis of local heating: now lets analyze the reasons for this phenomenon: the integrated IC inside, all is by the crystal semiconductor into enough, crystal semiconductor and stable work, must have a stable temperature and humidity.If the mobile phone be affected with damp be affected with damp or continuous work under harsh environment, by the nature of the semiconductor, mobile phone cant wor |
