2, wireless charging good. Wireless charging charger and charged equipment without direct contact, easy to use, strong environmental adaptability, avoid wireless charging line processing physical interface so there will be no interface wear, sparks, leakage and other problems, in addition to wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
3, wireless charging and wired charging have advantages, choose whichIt depends on the specific use case and requirements. The advantages of wireless charging Wireless charging cable processing : Convenience: Wireless charging does not need to insert or pull out the charging cable, just put the device on the charger to start charging, very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.
4, often use wireless charging has no effect on the phone battery. Wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone. Wireless charging uses electromagnetic inductionPrinciple, through the coil coupling to achieve the transfer of energy. Wireless charging technology of mobile phone is a kind of circuit which is converted into charging circuit through transmitting circuit through power management module.
5, wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, offer wireless charging services where users simply place their phones on the charging mat without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
However, it is a device that uses the principle of electromagnetic induction to charge, does not need a charging line, and can be charged only by relying on electromagnetic waves. Its interior is mainly composed of various types of coils, so the external needs to be coated to play a better protective role.
2, you can package glue, this need to pay attention to TPE must be baked, can not contain water. Just a little bit higher temperature.
3, package to see what you package, power tools generally use TPE package, TPE can package PP, ABS, PA, PC and so on.

The charging pile industry faces the problems of large initial investment, long investment return cycle and high industry barriers, but it still has a huge market potentialForce.
1, Vicos wireless charging line inflation quality is good. According to the query of relevant information, Vicos is a professional wireless charging manufacturers, quality refers to the trust.
For example, for the 6-10 layer memory module PCB design, choose 10/20mil (drill/pad)Holes are better, and for some high-density small-size boards, you can also try to use 8/18Mil holes. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); For the power supply or ground wire hole, you can consider using a larger size to reduce the impedance.
In the range of ravg 0~0.08 m, the output power increases first and then decreases with the increase of coil turns; In the range of ravg 0.08~ 0.4m, the output power decreases with the increase of coil turnsThen it increases and then it decreases. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the material used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.
Wireless charging PCB, different functions, the required components are different. The required components are wireless charging line processing : resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Control chip Wireless charging line processing : Manage the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
Electric field coupling technology transmits energy wirelessly, although it is less energy efficient, but the most convenient to use. The principle of wireless charging is similar to that of transformer, and the system design refers to the structure of transformer. Wireless charging products are mainly composed of a receiving end and a transmitting end, which includes a chip and a vibrationSwappers, power amplifiers, coils, PCB, passive devices, electronic transformers, structural parts, etc., the receiving end is divided into two parts: chip and module.
