- Multimeter: Measure the voltage, current, resistance and other parameters of the circuit to help determine whether the circuit is normal.
2. Professional Equipment:
-
Oscilloscope: Used to observe the signal waveform in the circuit, help analyze the frequency, amplitude, phase and other parameters of the signal, and is very helpful for repairing RF circuits and audio circuits.
-
Spectrum analyzer: used to analyze the spectrum of mobile phone signals, help determine the signal strength, frequency, modulation mode and other parameters, which is very helpful for repairing radio frequency circuits.
-
Cell Phone Repair Fixture: used to fix mobile phones for easy disassembly and repair operations.
- DC regulated power supply: used to provide stable power to mobile phones for testing and debugging during repair.
Maintenance Skills
1. Fault diagnosis:
- Observation method: observe the appearance, screen display, indicator light status, etc. of the mobile phone to preliminarily determine the possible cause of the fault.
- Test method: use multimeter, Oscilloscope and other test tools to test the circuit of the mobile phone and find out the fault point.
- Replacement method: replace the suspected faulty parts with normal parts, observe whether the fault of the mobile phone disappears, and thus determine the fault point.
2. Disassembly and assembly:
- Mastering skills: master the disassembly and assembly skills of various mobile phones, and be careful not to damage the parts and cables of the mobile phone during the disassembly process.
- Precautions: When disassembling and assembling mobile phones, pay attention to electrostatic protection to avoid static electricity from damaging the parts of the mobile phone. At the same time, pay attention to the preservation of the disassembled screws and parts to avoid loss.
3. Welding technology:
- Manual welding: Master the basic skills of manual welding, such as how to control welding temperature, welding time, welding angle, etc., to ensure welding quality.
- Hot air gun welding: Master the skills of Hot Air Gun welding, such as how to adjust the temperature and wind speed of the hot air gun, how to choose the appropriate nozzle, etc., to ensure welding quality.
4. Software repair:
- Flashing: Master the methods and skills of mobile phone flashing, and be able to choose the appropriate flashing tools and flashing packages according to different mobile phone models and fault conditions.
- Repair system: Learn to use professional software tools to repair the system files and registry of the mobile phone and solve system faults.
- Data recovery: Master the methods and skills of mobile phone data recovery, and be able to recover lost data without damaging the mobile phone data.
Safety Precautions
1. Static electricity protection
Understand the hazards: Static electricity may cause damage to the electronic components of the mobile phone, so pay attention to static electricity protection when repairing the mobile phone.
Take measures: You can use tools such as anti-static wristbands and Anti-static Mats to avoid repair operations in a dry environment to reduce the generation of static electricity.
2. Operational specifications
Follow the process: When repairing a mobile phone, follow the correct operating procedures to avoid damage to the phone or personal injury due to improper operation.
Pay attention to safety: When using repair tools and equipment, pay attention to safety, such as avoiding electric shock, burns, etc.
