Today to share the knowledge of wireless circuit board where the heat, which will also explain the principle of wireless charging circuit board, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, the mobile phone will have some heat when charging, which is normal, because there will be a certain loss of electrical energy in the charging process, this part of the electrical energy into heat will make the mobile phone and the charger to keep warm, such as the use of mobile phone temperature will be higher when charging.
2You want to ask why the back of the Apple mobile phone wireless charger is hot? It's a normal phenomenon. When an iPhone is charged using a wireless charger, it is normal for the back of the phone to get hot. This is because when wireless charging, the phone's built-in battery will accept the electrical energy from the charger and convert it into electrical energy storage. In this process, part of the electrical energy will be converted into heat, causing the back of the phone to burn. 3, in summary, wireless charging mobile phone hot is a normal phenomenon, mainly caused by the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation design and use of the environment and other factors. inUse the Xiaomi phone Assistant to swipe the system to the latest version.
Charging treasure charging burned the motherboard has been hot, should be the motherboard and battery on the line cut as soon as possible to avoid short circuit, the battery burned.
If the laptop cannot be turned on (does not turn on/does not turn on), the problem may be caused by static electricity on the motherboard. In this case, follow the steps below. (1) Please insert and remove the adapter and battery. (If the battery is not removable, just plug and remove the adapter.) (2) Press and hold the power button for about 10 seconds, this will clear the static electricity on the motherboard. The charging hot component is called the power management chip, which is the most important active component of the charging treasure motherboard. Not only charge to use, discharge to charge the mobile phone also need to use, but also manage the power indicator light and lighting. It is normal for the power management chip to get hot during operation,But the surface temperature should not exceed 80 degrees Celsius. Generally, it is very hot when touched by hand, which is normal. Of course, the lower the temperature at work, the better the chip quality and the surrounding circuit. The plug connected to the charging treasure is the charging treasure USB0 output port. There are roughly two reasons for overheating: the booster conversion rate of the charging treasure motherboard is too low - the booster conversion rate of the charging treasure is lower than 0.80, and the hot motherboard is quite serious. The USB0 plug metal shell will concentrate the heat of the mainboard, so the feel temperature is higher than other parts. According to your description, the mobile phone in the working state such as charging, making calls or surfing the Internet for a long time, running the game, if the machine has a slight heat situation, this is because the mobile phone will produce the corresponding power when working, the power will generate part of the heat, which is a normal phenomenon. If the machine heats abnormally, it is recommended to check whether the phone is used for too long, such as calling, surfing the Internet, listening to music or playing games. It is normal for mobile phones to heat up when charging, especially for mobile phones that support fast charging and super fast charging. When charging, the current and voltage are larger, so the temperature will be higher than thatNormal charging is higher. If you use a Huawei mobile phone, to avoid serious heat, you are advised to: Use the standard charger to charge the phone. The mobile phone will be hot when charging, which is a common phenomenon, the mobile phone and the charger will be slightly hot when charging, energy conversion and internal resistance consumption will produce a certain amount of heat, but please rest assured that our mobile phone has passed a strict safety test before the factory, there will be no safety risks. Charging state, in the charging state, the battery will generate heat, which is a normal phenomenon. (2) Playing large mobile games or applications will take up a lot of CPU powerThe source. (3) When using the mobile phone under charging state, it is recommended to use it after full charge. (4) The use of mobile phones in a closed environment, because the mobile phone is in a closed state, the heat does not go out, will lead to serious fever, it is recommended to use in a better ventilated environment. It is normal for coils to heat up. You need to increase the diameter of the copper wire. There's too much current in there. Temperature control circuit. General wireless charging scheme willWith a temperature control circuit and NTC thermistor, this function is mainly to prevent the heat generated by the circuit in the process of working too high, burn components, etc., can also control the power components after generating too much heat, reduce the power, thereby reducing the temperature. Selection of heating components. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work. The mobile phone will have some heat when charging, which is normal, because in the charging process there will be a certain loss of electrical energy, this part of the electrical energy into heat will make the mobile phone and the charger to keep warm, such as the use of hands when chargingThe machine temperature will be higher. About the wireless circuit board where the introduction of heat and wireless charging circuit board principle is over, do not know you find the information you need? If you want to know more about this, remember to follow this site. < / p > What is the mobile phone charging motherboardDoes it heat
