Mobile phones are now widely used, and problems need to be repaired. What are the commonly used tools for repairing mobile phones?
Method / Step
-
The multimeter is indispensable and is used to measure voltage, resistance, capacitance, and other parameters.
-
This is also required for an oscilloscope. It is necessary to measure whether the signal waveform is output normally and whether the voltage fluctuates.
-
A spectrum analyzer, which mainly measures RF signals, can measure wireless signal parameters such as RF signal strength and center frequency error.
-
Hot air guns and electric irons, these are commonly used tools for disassembling electronic devices and soldering devices.
-
Adjustable regulated power supply, this can provide a stable voltage to the circuit for testing.
-
Magnifying glass and screwdrivers, tweezers and other small things are also essential.
