Tools required for short-circuit detection in mobile phones

Instructions:TS-30A TS-20A Short Circuit Detection Instruments are also often used to explore the short circuit on the line print.On a level,they can quickly identify short circuit issues and provide audio or visual indicators to help the technician find exactly where the short is located.

　　Line testers:A multimeter can be used to check for a short circuit in a circuit.It also has a"buzzer mode"or"resistance mode"that allows it to short circuit in the power line,and measure voltage and current.

　　Thermal imager:This helps find short circuit problematic cases,thermal imagers can see temperature distribution on a board.Most short circuit zone creating abnormal heat,which you see with a thermal imager,can localize the problem.

　　Oscilleoscop:If you are experienced enough,you can use an oscilloscope to analyze the power signal or the output of the battery management system to check whether there is a fluctuating signal or the unstable light,which may indicate a short circuit or circuit failure.

　　Some battery repair tools can detect information such as voltage,and current,and further confirm whether the battery needs to be replaced if a short circuit is found to be caused by a bad battery

　　Microscope:Microscopes are a very handy tool in the repair process,particularly when identifying small solder joints,open circuits,or bad soldering.Small solder joints on a phone's motherboard are capable of causing short circuits,and microscopes can help technicians better inspect and repair those problems.

　　soldering tools:The short circuit is caused by bad soldering,Therefore,soldering tools(Soldering Irons,flux,solder,etc.)will repair the solder joints to see if the circuit connected well.
