1. Screwdriver: When repairing a mobile phone, a screwdriver is required to open the case (some phone cases are snap-on without a screwdriver). Most of the screws use hexagonal screws; different mobile phones have different specifications, generally T5, T6, T7, T8, etc., some models are also equipped with special screws, you need a special screwdriver. In addition, you need to prepare a small screwdriver with a small screwdriver. When choosing this kind of tool, you can choose the A and B sets of approved, it includes almost all mobile phone opening tools. When opening the case, select the appropriate screwdriver according to the types and specifications of the fixing screws on the case. If the selection is not appropriate, the groove of the screw may be flattened, causing slipping. 2. Tweezers: Tweezers are tools often used in mobile phone repairs, and they are often used to hold wires, components, and integrated circuit pins. Different occasions require different tweezers. Generally, one pair of straight, flat and elbow tweezers should be prepared. A common choice is a pair of steel tweezers of good quality. 3. Electric soldering iron: In the maintenance of mobile phones, the components on the circuit board are often replaced, and an electric soldering iron is required, and the requirements on it are also very high. This is because the components of the mobile phone use surface mount technology, the components are small, the integration is very high, the printed circuit is fine, and the pad is small. If the electric soldering iron is not properly selected, it is easy to cause man-made failures during the soldering process, such as virtual soldering, short circuit, or even soldering the circuit board. Therefore, it is necessary to use high-end electric soldering irons as much as possible, such as using a thermostat to prevent static electricity. In addition, some large devices such as shielding shields require high-power soldering irons, so an ordinary thick-headed soldering iron of more than 60W must be prepared. 4. Hot air gun: Hot air gun is one of the most used tools in mobile phone repair, and the process requirements are also very high. Hot air guns are used from removing or installing small components to large integrated circuits. In different occasions, there are special requirements for the temperature and air volume of the hot air gun. If the temperature is too low, it will cause virtual soldering of the component, and if the temperature is too high, the component and the circuit board will be the worst. Excessive air volume will blow away small components, and the selection of hot air guns is also very important. Don't choose low-grade hot air guns because of price issues. 5. Flux: Mobile phone soldering requires the use of flux to avoid virtual soldering or burrs on the solder joint surface. The solder paste that resists is generally corrosive and cannot be used for mobile phone repairs. Rosin is very practical (configured with Tianna water and rosin), and it is cheap, but it needs to be cleaned after welding. 6. Washing water: The use environment of mobile phones is relatively harsh, and it is susceptible to moisture, dust, and even mildew into the water. Especially when using non-no-clean flux during welding, the mobile phone must be cleaned. The printed circuit board should be cleaned with washing water. If there is no washing water, ethane or natural water can also be used for cleaning. Please pay attention to the organic materials such as the display, cabinet, microphone, ringing, etc. when cleaning . Seven, suction tin belt: The tin suction tape is very important in the repair of mobile phones. It has a strong adsorption capacity for solder. There is too much solder on the board or the solder joint is short-circuited. In the repair of mobile phones, 1.5mm-2mm wide soldering tape is generally used. 8. Anti-static equipment: To prevent damage to mobile phone components caused by static electricity, anti-static table mats, anti-static wrist straps, and anti-static soldering stations can be used. These devices must be properly grounded. Nine, multimeter: Multimeter is a kind of multimeter that can measure the parameters of current, voltage, resistance, crystal diode and transistor, and it is also a kind of instrument necessary for manufacturing and repairing various communication products and other electromechanical products. It is one of the most commonly used maintenance instruments in mobile phone repair. It mainly tests the voltage of each key point, the continuity of the circuit and judges the quality of the components. There are many types of multimeters currently on the market, but they can be divided into two types, one is a pointer multimeter and the other is a digital multimeter. These two types of multimeters have different uses in mobile phone repairs, but digital multimeters are widely used for their high accuracy and intuitiveness. Ten, stabilized power supply: In the maintenance of mobile phones, for the convenience of testing, a regulated power supply needs to be prepared, whose output voltage is adjustable, the output voltage is 1-15 volts, the current is 1-2 amps, it should be equipped with a short-circuit protection circuit and current limit adjustment, and has a mechanical type There are two types of meter and digital display, which are used to observe the current changes in the mobile phone.
