Are there any requirements for the production of magnetic spacers for wireless chargers?

Author:admin   AddTime:2021-08-07

Hello everyone, do all my friends know what are the requirements for the production of magnetic spacers for wireless chargers? Today, the editor will give you a detailed explanation.
 

It is believed that wireless charging has become more and more popular among consumers. Moreover, domestic mobile phone brands Huawei, Xiaomi, OPPP and VIVO have all equipped their flagship mobile phones with wireless charging as standard, so a good wireless charger is It is necessary to have a size magnetic isolation sheet to improve the charging efficiency and the role of safety isolation. Magnetic isolation sheet This material uses the electron scattering and the interaction between electrons and electrons caused by the thermal motion of the functional component lattice electric field to absorb electromagnetic wave energy and convert it into heat energy. So as to achieve the purpose of attenuating electromagnetic waves. In order to achieve different shielding effects under different conditions, we can choose different thickness materials and different performance magnetic sheets.


 
The requirements for the production of magnetic sheets for wireless chargers are as follows:
 
1) Excellent magnetic performance and high permeability;
 
2) The magnetic loss of the magnetic sheet in the AC magnetic field is small;
 
3) The magnetic sheet has good flexibility and will not break when being laminated, otherwise it will cause magnetic flux leakage;
 
As a fashionable and convenient charging method, wireless charging is more and more favored by consumers, and it is developing rapidly in the field of consumer electronic products such as mobile phones and game consoles. However, wireless chargers have disadvantages such as low charging efficiency and large heat generation during charging. In order to improve the charging efficiency and ensure the safety of use, the current mainstream solution is to attach magnetic spacers to the back of the wireless charger transmitter and receiver coils.
