What are the steps for short circuit detection during handle repair?

Step 1:Preliminary inspection:Check if there is no obvious damage on the outside of the phone,such as cracked screens,swollen batteries,loose charging ports,etc.

　　Pseće i zola:Pseće i zola:Sefleske pobece sve sume(kakva se krake dva moze udariti sa jednostavna,bacite)The tool will check for a short circuit by detecting a difference in current as well as voltage then prompt you if any change occurs.

　　Inspect the power area carefully:The multimeter can also be used to check the power area,charging port,and battery connection to see if there is a short circuit.

　　Step 2:Check internal components:When using a Microscope to check the motherboard,check whether the components are obviously damaged,burned or poorly welded.Re-soldering may be required.

　　Thermographic inspection:If you suspect some areas are overheating,you can open it impermeability to detect whether there are overheated parts on the circuit board.Generally,this indicates that there may be a short circuit.

　　Get together and test:Once the origin of the short circuit has been identified,make the necessary repairs or replacement.Test the phone again after the fix,there is no short circuit,then the phone back to normal.

　　Many mobile phone repair traces need the short circuit detection.It does not only aid technicians in quickly locating the problem,it also prevents further damage created from short circuits.Even for the short circuit detection tools are indispensable,when the phone fails to turn on,abnormal charge,water entry,drop and so on appears.The short circuit detectors,multimeters,infrared thermal imagers and microscopes,etc.are the common detection tools.These tools enable the maintenance staff to accurately and quickly diagnose potential issues,thus ensuring enhanced efficiency and success rate of maintenance.
