The first item people pick up when they wake up in the morning and the last thing they put down at night before going to bed. We play our phones in the car and even take our phones with us when we go to the toilet. Some people even value their smartphone more than their lovers. It is precisely with the increasing frequency of mobile phone use that the probability of failure is also increasing. Therefore, the maintenance of mobile phones become a common thing in our daily life.
With the continuous upgrading of mobile phones, it has become a highly integrated product, and the difficulty of maintenance is becoming more and more difficult. Now the failure is often can’t be solved by mobile phone repair shops. It is more common to replace a certain component. So what tools are needed for mobile phone maintenance? Common mobile phone repair instruments and tools include mobile phone accessories, maintenance tools, testing instruments, maintenance instruments, etc. Let's take a detailed look at the relevant knowledge.
Tools Needed to Repair Your Phone
1. Screwdriver: When fixing a mobile phone, a screwdriver is required to open the shell (some mobile phone shells are snap-fastened without screws).
2. Tweezers: soldering Tweezers are a tool that is often used in mobile phone maintenance, and it is often used to clamp wires, components and integrated circuit pins.
3. Soldering station:
Because mobile phone maintenance usually has small size, high integration, fine circuit and small pad, the selection of soldering station and the use of soldering iron are also relatively high.
4. Hot air gun: Hot air gun is one of the most commonly used tools in mobile phone maintenance, and the requirements for using skills are also very high.
5. Flux: It is necessary to use flux for mobile phone soldering to avoid false soldering or burrs on the surface of solder joints.
6. PCB cleaner: The use environment of mobile phones is relatively harsh, and it is easy to be affected by moisture, dust, and even mildew due to water immerse. Especially when non-disposable flux is used for soldering, it is necessary to clean the mobile phone.
7. Desoldering wick wire: It is very important in the maintenance of mobile phones. It has a strong adsorption capacity for solder. If there is too much solder on the board or the solder joint is short-circuited, it is easy to use the desoldering wick wire.
8. Maintenance power supply
In mobile phone maintenance, in order to facilitate testing, a regulated power supply needs to be prepared, and its output voltage is required to be adjustable, with an output voltage of 1-15 volts and a current of 1-2 amps. The short circuit protection circuit and current limiting adjustment functions are needed. There are two ways to observe the current changes in the work of the mobile phone, include mechanical meter head and digital display.
9. Software maintenance device
The software in the mobile phone is constantly lost or disordered, resulting in various software failures, and it is necessary to use a special software maintenance device to rewrite the software.
The software maintenance device is divided into two types: disassemble and disassembly-free.
a. With a disassembly-free software maintenance device, we don’t not need to open the shell of the mobile phone, but it requires us to store the required software data in the computer in advance, and rewrite the software in the mobile phone through the data transmission line and the software maintenance device.
b. Disassembly software maintenance device: There is no software data of a certain model in the free disassembly maintenance device, or the mobile phone cannot be connected to the maintenance device, and can only be disassembled and rewritten with a special universal programming device.
10. Large screen industrial microscope:
The circuit board of a mobile phone is delicate and dense. When repairing, an amplifier is needed to help find and repair the small components on the circuit board easily. So a magnifying table lamp is essential.
11. Spectrum analyzer:
Spectrum analyzer is expensive and complicated to operate, and it need to be used with a signal generator. It can easily find the fault of the mobile phone, which can effectively improve the work efficiency.
12. Universal meter
The universal meter is a multi-purpose meter used to measure the current, voltage, resistance, crystal diode and transistor parameters of mobile phones, and it is also an indispensable instrument for maintainers and manufacturers.
The above are the tools we need when repairing mobile phones. The quality of each tool is also very important for repairing mobile phones. Therefore, when buying tools, you must look for brands with quality assurance.
