As the saying goes: If a worker wants to do his job well, he must first sharpen his tools. An excellent mobile phone repair engineer must have a set of useful repair tools. Today we introduce some commonly used mobile phone repair tools.

Repair power

The mobile phone does not have a dedicated interface for the diagnostic card like a computer, so it is impossible to intuitively judge where the mobile phone fault occurs. Therefore, professional maintenance personnel use the power supply to power the mobile phone motherboard and observe the change in the current displayed on the repair power supply to determine the motherboard. The fault and the most common short-circuit fault on the mobile phone motherboard can also be seen very intuitively through the magnitude of the current. The early mobile phone repair power supply is generally a 15v voltage, 2A current pointer type power supply. In recent years, as the performance of mobile phones has become more and more powerful, the working current has also increased. The current 1A or 2A can no longer meet the needs of mobile phones. The new mobile phones need at least a 3A power supply. If it is used to judge the burn-in of the short circuit May need a 5A power supply to meet.

Iron

The soldering iron is an essential tool in maintenance, and any operation of the motherboard repair must be realized through the soldering iron. The soldering iron actually relies on a heating circuit to provide heat to the soldering iron tip, so that the temperature on the soldering iron tip reaches the melting point of tin. However, this process only melts the tin touched by the soldering iron tip, and the heat energy on the soldering iron tip will be conducted away by the tin and PCB board, causing the temperature of the soldering iron tip to drop rapidly. If you want to operate the soldering in a fluent manner, the heating circuit of the soldering iron It is necessary to continuously provide heat energy to the soldering iron, which requires the power of the soldering iron to be large enough. So is it enough to increase the power alone to meet our requirements? The answer is no, there are many reasons for whether a soldering iron is easy to use. Welcome to consult our professional maintenance personnel on ORIWHIZ to get more information about mobile phone repair tools.

Hot air gun

Another indispensable piece of equipment in the repair of mobile phone motherboards is the air gun. Most people’s understanding of the air gun may still be in the era of the white light 850 air gun. The 850 air gun can be said to be a generation of artifacts. Every circuit board repair Basically all of the people have or have owned a white light 850 air gun or other domestic brands of 850 air guns. At present, in the mobile phone repair industry, the more standard configuration is a direct air gun and a cyclone air gun, which can adapt to different maintenance needs.

Multimeter

A multimeter is necessary measurement equipment in maintenance. The commonly used measuring voltage, resistance, and diode value must be measured with a multimeter. In fact, the accuracy of the multimeter is not high for mobile phone repair, and most of the values ​​can be accurate. Two digits after the decimal point will do.

Microscope

The area of ​​the mobile phone motherboard is relatively small and the precision is very high. Some precision operations cannot be done by the human eye at all. Ordinary magnifying glasses are also helpless in mobile phone repair. In this case, a special optical instrument ---- a microscope is required. In recent years, due to the trend of miniaturization of circuit boards, microscopes have also become one of the essential tools for mobile phone repairs.

Disassemble tool

The main point of the disassembly tool is to talk about the screwdriver. When choosing a screwdriver, pay attention to the sliding degree and durability of the screwdriver's bearing. When most people use a screwdriver, the bearing part of the screwdriver is placed on the palm of the hand. Use your index finger and finger. Turning the handle, if the bearing quality of the screwdriver is not good, you will feel very uncomfortable.

Tweezers

Tweezers are frequently used in repairs. Tweezers are required for desoldering, testing, and installation. Generally speaking, tweezers for mobile phone repair require high hardness, a sharp head, corrosion resistance, and non-magnetism.
